Question 1

Choose the pair of words in which the relationship between the two words is different from the relationship in the other pairs.

Accepted Answer

Introduction / Context: This question tests your ability to classify word pairs based on the type of relationship they represent. Four of the pairs show one type of logical connection, while one pair represents a different kind of link. Your job is to find the pair whose relationship does not match the others. Given Data / Assumptions: Farmer : Plough. Butcher : Chopper. Author : Book. Jockey : Tack. Carpenter : Hammer. All of these pairs involve a person and an object or product related to that person role. Concept / Approach: A useful approach is to decide whether the second word in each pair is primarily a tool used by the person, or something produced by the person. If four pairs show a \"user : tool\" or \"worker : instrument\" relationship and one pair shows a \"creator : product\" relationship, then the latter will be the odd one out. Classification questions often hinge on this sort of subtle difference. Step-by-Step Solution: Step 1: Look at \"Farmer : Plough\". A plough is a tool used by a farmer for tilling the soil. This pair clearly shows a worker and a work tool.Step 2: Consider \"Butcher : Chopper\". A chopper is a large knife or cleaver used by a butcher to cut meat. Again, this is a worker and the tool or instrument used in the job.Step 3: Analyse \"Jockey : Tack\". Tack refers to the riding equipment such as saddles and bridles used in horse riding. A jockey uses this tack while riding horses. This is again a professional and equipment relationship.Step 4: Examine \"Carpenter : Hammer\". A hammer is one of the most common tools used by a carpenter in woodworking. This fits perfectly into the worker and tool category.Step 5: Now look at \"Author : Book\". An author does not use a book as a tool in the same sense. Instead, the book is the product or creation of the author efforts. The relationship here is creator and creation, not user and instrument.Step 6: Compare the type of relationship: in four pairs the second word is a piece of equipment essential for performing the work; in one pair, the second word is the outcome of the work.Step 7: Therefore, \"Author : Book\" is the pair that is differently related. Verification / Alternative check: Ask yourself, \"Can the first person carry out their typical work without the second item?\" A farmer cannot properly plough fields without a plough, a butcher needs cutting tools like a chopper, a jockey needs tack to ride professionally, and a carpenter heavily relies on a hammer and similar tools. An author, however, does not use a finished book as a tool to write; they may use a pen, keyboard or computer. The book is the result after the writing is complete, which confirms the different relationship. Why Other Options Are Wrong: Farmer : Plough, Butcher : Chopper, Jockey : Tack and Carpenter : Hammer all show the same clear pattern: a worker and an instrument used in that work. Since they share the same type of link, they are not the odd pair. Only Author : Book breaks this pattern by showing a creator and a finished product. Common Pitfalls: Candidates sometimes think too literally and focus only on whether the words are related at all. All these pairs are related, but that is not enough. You must look at how they are related. Another common mistake is to confuse tools with products. Remember, a tool is used to perform work, while a product is the outcome of that work. Final Answer: The pair in which the words are differently related is Author : Book.

Question 2

Three of the following four letter groups are alike in a certain pattern. Choose the one letter group that does not belong to this pattern.

Accepted Answer

Introduction / Context: This is a classification question involving groups of letters. You are given several three letter sequences and asked to choose the one that does not follow the same pattern as the others. Such problems are common in logical reasoning sections and they test your ability to recognise patterns based on alphabetical positions. Given Data / Assumptions: The letter groups are GCU, ECO, DBJ, FDX and RNI. All groups contain three English uppercase letters. We assume the standard alphabetical positions: A=1, B=2, C=3, ..., Z=26. Typically, there is a fixed numeric pattern in the differences between letters inside each group. Concept / Approach: With letter group questions, a reliable approach is to convert each letter to its numerical position in the alphabet and then examine the differences between consecutive letters. If three or four groups show the same difference pattern and one group does not, that group is the odd one out. Here, we expect to find a simple, repeated difference pattern such as \"minus 3, minus 1\" or similar. Step-by-Step Solution: Step 1: Convert each letter to its numerical position.For GCU: G=7, C=3, U=21.For ECO: E=5, C=3, O=15.For DBJ: D=4, B=2, J=10.For FDX: F=6, D=4, X=24.For RNI: R=18, N=14, I=9.Step 2: Compute the differences between the first and second letters, and between the second and third letters, in each group.ECO: 5 to 3 is -2, and 3 to 15 is +12. Instead of mixing positive and negative, we usually look at absolute steps: 5 - 3 = 2 and 15 - 3 = 12.DBJ: 4 to 2 is a difference of 2, and 10 to 2 is a difference of 8.FDX: 6 to 4 is a difference of 2, and 24 to 4 is a difference of 20.RNI: 18 to 14 is a difference of 4, and 14 to 9 is a difference of 5. This forms a different pattern and is placed as a filler option.Step 3: Focus on the first three options, which are part of the original question: GCU, ECO and DBJ, plus FDX.DBJ and FDX both have the first two letters separated by exactly 2 positions (D to B, F to D). ECO also has E to C as a difference of 2. So ECO, DBJ and FDX share a common pattern of a 2 letter step between the first two letters.Step 4: For GCU, the first two letters G (7) and C (3) differ by 4 positions, not 2.Step 5: This means GCU does not follow the same \"first letter to second letter\" distance pattern as ECO, DBJ and FDX.Step 6: Therefore, GCU is the group that does not fit the common pattern and is the odd one out. Verification / Alternative check: Another way to see this is to focus only on the first two letters of each original option: G-C, E-C, D-B and F-D. From E to C is a move of 2 letters backward. From D to B is also 2 letters backward. From F to D is 2 letters backward again. Only from G to C is a move of 4 letters backward. When three items follow an identical jump of 2 positions and one does not, the one that breaks the rule is clearly the odd group. Why Other Options Are Wrong: ECO, DBJ and FDX follow the same structure with a consistent difference of 2 between the first and second letters. They form the majority pattern and therefore cannot be the odd one out. RNI is an extra distractor in the enhanced option set and is not part of the original four way comparison. Within the original four, only GCU breaks the dominant pattern. Common Pitfalls: Many test takers try to look for complicated patterns involving all three letters at once and may miss the simple 2 letter difference pattern between the first and second letters. Another mistake is to focus only on the last two letters, where the differences vary more. For classification problems, always try simple and consistent rules first: differences of 1, 2 or 3 steps between consecutive letters often reveal the hidden pattern. Final Answer: The letter group that does not belong to the pattern is GCU.

Question 3

In the code PROBLEM : 2948375, three of the following four word–number pairs follow the same letter–digit relationship. Choose the pair that does not follow this relationship.

Accepted Answer

Introduction / Context: This question is about letter to digit coding. You are given a reference code, PROBLEM : 2948375, and several other word–number pairs. Three of those pairs follow exactly the same coding rule as the reference, and one pair breaks the rule. You must identify the incorrect or differently related pair. Given Data / Assumptions: Reference code: PROBLEM is coded as 2948375. Option A: BORE : 8497. Option B: MOEP : 5972. Option C: LBOR : 3849. Option D: OMEP : 4572. Option E: ROLE : 9477 (extra plausible pair added as a distractor in the enhanced options; the original test comparison focuses on A to D). The task is to deduce the mapping between letters in PROBLEM and digits in 2948375, then verify each option against that mapping. Concept / Approach: The first step is to map each distinct letter in the word PROBLEM to the digit above or below it in the code 2948375. Once we have a complete mapping for P, R, O, B, L, E and M, we apply the same mapping to the letters in BORE, MOEP, LBOR and OMEP. A correct pair will match the mapping exactly; any mismatch marks the odd pair out. Step-by-Step Solution: Step 1: Align PROBLEM with 2948375.P R O B L E M2 9 4 8 3 7 5Step 2: From this alignment, deduce the letter–digit mapping.P → 2, R → 9, O → 4, B → 8, L → 3, E → 7, M → 5.Step 3: Apply this mapping to each option.For BORE: B → 8, O → 4, R → 9, E → 7, so the correct code is 8497. Option A gives 8497, which is correct.For LBOR: L → 3, B → 8, O → 4, R → 9, so the correct code is 3849. Option C gives 3849, which is correct.For OMEP: O → 4, M → 5, E → 7, P → 2, so the correct code is 4572. Option D gives 4572, which is correct.Step 4: Now check MOEP.For MOEP: M → 5, O → 4, E → 7, P → 2, so the correct code should be 5472.Step 5: Option B gives MOEP : 5972, which uses 9 instead of 4 for the letter O. This does not match the established mapping.Step 6: Therefore, MOEP : 5972 does not follow the same coding rule as PROBLEM : 2948375 and is the differently related pair. Verification / Alternative check: You can also verify by checking just the letter O, which is easy to track. In the reference, O is mapped to 4. Any correctly coded word containing O must therefore show the digit 4 in the position of O. In BORE, the second letter O maps to 4, which is present. In LBOR, the third letter O maps to 4, which appears correctly as the third digit. In OMEP, the first letter O maps to 4, and the code begins with 4. But in MOEP, the second letter is O, yet the second digit is 9, not 4. This quick check alone is enough to reveal the mismatch. Why Other Options Are Wrong: Options A, C and D all respect the original mapping without any conflict. They simply rearrange the same letters PROBLEM and map each letter to its correct digit. Since they are consistent with the code pattern, they are not the odd ones. Option E is an additional distractor for extended practice. Within the original set of four comparison pairs, only MOEP : 5972 violates the coding rule. Common Pitfalls: Some candidates attempt to infer a complicated rule based on letter positions in the alphabet, which is not necessary here. The mapping is direct and positional from the reference word and its code. Another mistake is to misalign letters and digits when reading the reference, which leads to a wrong mapping. Always write the letters and digits in one clear row before mapping. Final Answer: The pair that does not follow the given letter–digit coding relationship is MOEP : 5972.

Question 4

Four of the following five words are units of length and so form a group. Choose the one word that does not belong to this group.

Accepted Answer

Introduction / Context: This is a simple classification question dealing with measurement units. You are asked to identify which word among the given options does not represent the same kind of physical quantity as the others. Such questions test your basic knowledge of everyday and scientific units. Given Data / Assumptions: The words given are Metre, Furlong, Yard, Mile and Acre. All of them are commonly used in measurement contexts. Metre is the SI unit of length. Furlong, yard and mile are traditional units of distance or length. Acre is a commonly used unit in land measurement. Concept / Approach: The core idea is to classify each word according to what it measures: length, area, volume or something else. If four items measure the same quantity and one measures a different quantity, then that one is the odd one out. Here the majority of terms are units of length or distance, and we need to check whether Acre follows the same category or not. Step-by-Step Solution: Step 1: Metre is a standard unit of length used in the metric system. It measures one dimensional distance.Step 2: Yard is an imperial or customary unit of length, often used in countries that use the imperial system.Step 3: Mile is another traditional unit of length, used especially for longer distances such as road travel.Step 4: Furlong is an older unit of length, traditionally used in agriculture and horse racing, equivalent to one eighth of a mile.Step 5: All four of these units (Metre, Yard, Mile, Furlong) measure one dimensional distance or length.Step 6: Acre, by contrast, is a unit of area, not length. It is used to measure the size of land, and represents a two dimensional measurement (length multiplied by width).Step 7: Therefore, four options are units of length, and Acre is a unit of area.Step 8: The word that does not belong to the group of length units is Acre. Verification / Alternative check: To confirm, imagine what question each unit answers. Metre answers \"how long\" is something. Yard and Mile also answer \"how long\" or \"how far\". Furlong answers \"what distance\" for old racing tracks. Acre, however, answers \"how large is this piece of land\" in terms of surface area. You cannot use Acre to measure the length of a road or the height of a building, which again shows the category difference. Why Other Options Are Wrong: Metre, Furlong, Yard and Mile are all clearly units of length. Their numerical values or systems (metric vs imperial) may differ, but they belong to the same category of one dimensional measurement. Because they share the same type of quantity, they form the majority group and cannot be the odd one out. Only Acre measures a two dimensional quantity. Common Pitfalls: Sometimes candidates remember that Acre is strongly associated with land and fields but forget precisely that it measures area. Others may confuse Yard with a backyard or Mile with a milestone and get distracted by everyday meanings. To answer correctly, focus on the technical role as a unit and ask, \"Is this used to measure distance or something else?\" Final Answer: The word which does not belong with the others is Acre.

Question 5

Which of the following computer-related words does not belong with the others in the group?

Accepted Answer

Introduction / Context: This question is from the \"classification\" area of logical reasoning, focused on computer hardware. You are given several device names and asked to identify which one does not belong with the others. These questions test whether you can distinguish between different types of input and output devices commonly used with computers. Given Data / Assumptions: VDU (Visual Display Unit), usually meaning a computer monitor. Speakers, which produce sound output from the computer. Plotter, a special output device that produces large, precise drawings. Joystick, a pointing or control device used for input, especially in games. Printer, an output device that produces hard copy on paper. We assume basic familiarity with the concept of input devices and output devices. Concept / Approach: In computer terminology, devices are often classified as input devices, which send data into the computer, and output devices, which present processed data to the user. A natural approach to this question is to group the options into input and output devices. If most of the devices are output devices and only one is an input device, that input device becomes the odd one out. Step-by-Step Solution: Step 1: VDU or monitor is a visual output device. It displays text, images and video on a screen, so it is clearly an output device.Step 2: Speakers take digital audio signals from the computer and convert them to sound, which users can hear. This is also a form of output.Step 3: A plotter is a specialised output device used for high precision drawings, such as architectural plans or engineering diagrams. It produces physical output on paper or similar media.Step 4: A printer, like a plotter, is a standard output device that prints text and images on paper. It is also clearly an output device.Step 5: A joystick is used by a user to control movement or direction in games and simulations. When the user moves the joystick, signals are sent into the computer, making it an input device.Step 6: Hence, VDU, Speakers, Plotter and Printer are all output devices, whereas Joystick is an input device.Step 7: Since the question asks for the word that does not belong with the others, the only input device, Joystick, is the odd one out. Verification / Alternative check: Another quick way to verify is to think about direction of information flow. Ask, \"Does this device mainly take information from the computer and present it to the user, or does it take user actions and send them to the computer?\" Monitors, speakers, plotters and printers present information from the computer to the user, so the flow is computer to device. A joystick works in the opposite direction: user to computer. This confirms that joystick belongs to a different category. Why Other Options Are Wrong: VDU, speakers, plotter and printer all share the role of output devices. Although they handle different kinds of output (visual, audio or printed), their common function is to show or produce the results of computer processing. Since they fit together in the same functional category, none of them can be the odd one out. Only joystick does not fit this group. Common Pitfalls: A typical mistake is to focus on size or cost of devices, which is irrelevant here. Another is to think that plotter is unusual or outdated and therefore must be the odd one out. However, the test is about function, not popularity. Always classify devices by whether they are input, output, or storage devices when solving such questions. Final Answer: The word that does not belong with the others is Joystick.

Question 6

Three of the following four numbers share a similar property and form a group. Which number does not belong to this group?

Accepted Answer

Introduction / Context: This is a numerical classification question. You are given several numbers and must select the one that does not share a common property possessed by the others. Such questions check your ability to recognise patterns in divisibility and factorisation. Given Data / Assumptions: The numbers given are 20, 35, 45, 80 and 50. All of them are positive integers. Each number is a multiple of 5. We are looking for a more specific property that separates one number from the other three among the original options. Concept / Approach: Because all the numbers are divisible by 5, that alone cannot be the basis for classification. A deeper look at the prime factorisation is helpful. We can check whether the numbers are also divisible by 2 or 3, because those are small primes that often appear in reasoning patterns. If most of the numbers share an additional factor (like 2 or 3) along with 5, and one number does not, that number will be the odd one out. Step-by-Step Solution: Step 1: Factorise 20. We have 20 = 2 * 2 * 5 = 4 * 5. So 20 is a multiple of 5 and also a multiple of 2.Step 2: Factorise 45. We have 45 = 3 * 3 * 5 = 9 * 5. So 45 is a multiple of 5 and also a multiple of 3.Step 3: Factorise 80. We have 80 = 2 * 2 * 2 * 2 * 5 = 16 * 5. So 80 is a multiple of 5 and also a multiple of 2.Step 4: Factorise 35. We have 35 = 5 * 7. So 35 is a multiple of 5 and 7, but it is not divisible by 2 or 3.Step 5: Observe that in the original set 20, 35, 45 and 80, three numbers (20, 45, 80) are multiples of 5 and at least one of the small primes 2 or 3.Step 6: Specifically, 20 and 80 are multiples of 2, and 45 is a multiple of 3. All three therefore share the structure \"5 times 2 or 3\".Step 7: The number 35 is the only one that is a product of 5 and 7 and does not involve 2 or 3 in its prime factorisation.Step 8: Therefore, 35 is arithmetically different from the others and is the odd one out. Verification / Alternative check: A quick alternative check is to test divisibility. Check each number for divisibility by 2 or 3. 20 is even, so it is divisible by 2. 45 is divisible by 3 because 4 + 5 = 9, which is divisible by 3. 80 is even and therefore divisible by 2. 35 is neither even nor divisible by 3 because 3 + 5 = 8, which is not divisible by 3. Thus, three of the numbers (20, 45, 80) share the property \"divisible by 5 and also by 2 or 3\", while 35 does not. Why Other Options Are Wrong: 20 is not the odd one out because it fits the pattern of being a multiple of 5 and a multiple of 2. 45 fits as a multiple of 5 and 3. 80 fits as a multiple of 5 and 2. Any added practice number like 50 also remains a multiple of 5 and 2, so it is not special. Only 35, with its prime factorisation 5 * 7, fails to have 2 or 3 as an additional factor and therefore breaks the dominant pattern. Common Pitfalls: Some learners initially focus on superficial details such as whether the number is two digit or not, or whether it ends in 0 or 5. However, all are multiples of 5, so the real pattern is a bit subtler. Another error is to pick the largest or smallest number without doing any factor analysis. In any classification question, always check divisibility by small prime numbers to see hidden similarities and differences. Final Answer: The number which does not belong to the group is 35.

Question 7

Choose the pair in which the relationship between the two words is different from that in the other pairs.

Accepted Answer

Introduction / Context: This question checks your understanding of functional relationships between objects and the things they depend on. You are to pick the pair whose relationship is of a different type from the others. The words relate to ideas like fuel, energy and essential requirements. Given Data / Assumptions: Oil : Lamp. Water : Tap. Oxygen : Life. Power : Machine. Fuel : Engine. We assume usual everyday meanings: a lamp burning oil, water flowing from a tap, life depending on oxygen, a machine running on power, and an engine requiring fuel. Concept / Approach: Look for a common pattern among most pairs. In four of the pairs, the first word is something that is required for the proper functioning or existence of the second. In other words, the first word can be thought of as a \"fuel\", \"energy source\" or \"vital requirement\" for the second. The odd pair will be the one where this simple requirement relationship does not hold in the same way. Step-by-Step Solution: Step 1: Consider \"Oil : Lamp\". A traditional oil lamp needs oil as a fuel to burn and produce light. Without oil, the lamp cannot function as a lamp.Step 2: Look at \"Oxygen : Life\". Most forms of life, especially human life, require oxygen for breathing and cellular processes. Oxygen is essential for life to exist and continue.Step 3: Examine \"Power : Machine\". Machines generally require electrical power, mechanical power or some form of energy to run. Without power, the machine will not operate. So power is the essential energy source for the machine.Step 4: Check \"Fuel : Engine\". An engine needs fuel such as petrol or diesel to operate. Without fuel, the engine cannot run. This is clearly another requirement relationship.Step 5: Now turn to \"Water : Tap\". A tap is a device or fitting used to control the flow of water. It supplies water rather than requiring water to exist as an object. The tap is the mechanism, and water is the fluid that passes through it.Step 6: In this case, it is more natural to say that the tap provides water or controls water, rather than saying that water is an essential requirement for a tap to exist. The relationship direction is reversed compared to the other pairs.Step 7: Oil, oxygen, power and fuel are all needed by the second item (lamp, life, machine, engine) to function, but water is the product that a tap gives, not a required input in the same conceptual sense.Step 8: Therefore, Water : Tap is the pair that is differently related. Verification / Alternative check: Rephrase each pair as a sentence: \"A lamp needs oil\", \"Life needs oxygen\", \"A machine needs power\", \"An engine needs fuel\". All of these sentences sound natural and correct. Now try \"A tap needs water\". While a tap is used to supply water, the statement does not feel like the same kind of requirement relationship as the others. Instead, you would normally say \"A tap supplies water\". This confirms that the direction of dependence is different. Why Other Options Are Wrong: Oil : Lamp, Oxygen : Life, Power : Machine and Fuel : Engine all show the same basic pattern: the first item is a vital fuel, resource or energy source that the second item requires to perform its function. Because they share this pattern, none of them can be considered differently related. Water : Tap is the only pair where the first item is more clearly an output or content controlled by the second. Common Pitfalls: Candidates sometimes focus on whether the second item is living or non living, which is not relevant here. Others try to see whether the first item is liquid or gas, again not the key. The correct approach is to look at the direction of necessity: who needs what to function? Once you do that, the odd one out becomes clear. Final Answer: The pair which is differently related from the others is Water : Tap.

Question 8

Among the following metals, choose the one which is least like the others in the group.

Accepted Answer

Introduction / Context: This is a science based classification question that tests basic knowledge about metals and their physical states. You are asked to pick the metal which is least like the others in the group, given common metals such as zinc, aluminium, mercury, copper and iron. Given Data / Assumptions: The metals in the options are Zinc, Aluminium, Mercury, Copper and Iron. All are well known elements and conduct heat and electricity. Under normal conditions, most metals are solid at room temperature. We assume standard room temperature conditions as used in basic science (around 25 degrees Celsius). Concept / Approach: The usual way to approach this kind of question is to check for one metal that has a unique physical property compared with the others. A well known fact from basic chemistry is that almost all metals are solids at room temperature, with one famous exception. If four metals are solid and one is liquid at room temperature, the liquid metal will be the odd one out. Step-by-Step Solution: Step 1: Zinc is a bluish white metal that is solid at room temperature.Step 2: Aluminium is a light, silvery metal that is also solid at room temperature. It is widely used in utensils and engineering structures.Step 3: Copper is a reddish brown metal, solid at room temperature, often used in electrical wiring.Step 4: Iron is a hard, strong metal and is also solid at room temperature. It is used in construction, machinery and tools.Step 5: Mercury, however, is very different. It is a silvery metal that is liquid at room temperature. It has historically been used in thermometers and some electrical switches because of this liquid property.Step 6: Thus, zinc, aluminium, copper and iron are all solid metals at room temperature, whereas mercury is a liquid metal under the same conditions.Step 7: Therefore, mercury is the metal which is least like the others in the group. Verification / Alternative check: If you imagine holding a piece of each metal at room temperature, zinc, aluminium, copper and iron would all be solid pieces that you can pick up. Mercury cannot be picked up in the same way; it forms a shiny liquid that flows and takes the shape of its container. This simple mental picture confirms that mercury behaves differently from the others at everyday temperatures. Why Other Options Are Wrong: Zinc, aluminium, copper and iron share the common property of being solid metals at room temperature, even though they differ in colour, density and usage. Because they share similar state of matter under normal conditions, they form a natural group. They cannot be the odd one out since none of them stands apart in such a striking way as mercury does. Common Pitfalls: Some learners may be tempted to pick aluminium because it is lighter than the others, or copper because of its reddish colour. However, the question asks which metal is least like the others in a fundamental sense. The state of matter (solid versus liquid) at room temperature is a much stronger distinguishing feature than colour or density. Remembering that mercury is the only common metal that is liquid at room temperature will help in many similar questions. Final Answer: The metal which is least like the others is Mercury.

Question 9

Choose the number which is different from the others in the group based on a simple numerical property.

Accepted Answer

Introduction / Context: This numerical reasoning question asks you to identify which number is different from the others in the group. All the numbers appear fairly ordinary, so the difference lies in a hidden arithmetic property such as divisibility by a particular number. Given Data / Assumptions: The numbers are 380, 120, 290, 168 and 240. All the numbers are positive integers. Many classification questions are based on divisibility by 2, 3, 4 or other small integers. We are looking for a simple property shared by three of the four original numbers but not by the remaining one. Concept / Approach: A straightforward way to solve this type of question is to test each number for divisibility by a small integer such as 4, 6, 8 or 10. In many reasoning tests, differences based on being divisible or not divisible by 4 are common, because they can be checked quickly by looking at the last two digits of the number. Step-by-Step Solution: Step 1: Check divisibility by 4. A number is divisible by 4 if the number formed by its last two digits is divisible by 4.Step 2: For 380, the last two digits are 80. Since 80 ÷ 4 = 20, 380 is divisible by 4.Step 3: For 120, the last two digits are 20. Since 20 ÷ 4 = 5, 120 is divisible by 4.Step 4: For 168, the last two digits are 68. Since 68 ÷ 4 = 17, 168 is divisible by 4.Step 5: For 290, the last two digits are 90. Since 90 ÷ 4 does not give an integer (90 ÷ 4 = 22.5), 290 is not divisible by 4.Step 6: For comparison, 240 has last two digits 40, and 40 ÷ 4 = 10, so 240 is also divisible by 4.Step 7: Among the original four numbers (380, 120, 290, 168), three numbers (380, 120, 168) are divisible by 4, while 290 alone is not.Step 8: Therefore, 290 is the number that is different from the others based on divisibility by 4. Verification / Alternative check: You can verify this result by actually performing division. 380 ÷ 4 = 95, 120 ÷ 4 = 30, and 168 ÷ 4 = 42, all integers. But 290 ÷ 4 = 72.5, which is not an integer. For extended checking, notice that 290 is 29 × 10 and 29 is an odd prime that does not combine with 10 to produce a multiple of 4. Why Other Options Are Wrong: 380, 120 and 168 all share the property of being multiples of 4 in addition to other divisibility features. They therefore belong naturally in one group. Any extra practice number like 240 also fits that group as it is divisible by 4. Only 290 fails this simple divisibility test, so it cannot be grouped with the others on this property. Common Pitfalls: Some candidates may try to use more complicated properties, such as sum of digits or prime factorisation, which are unnecessary here. Others choose the largest or smallest number without justification. The safest strategy is to look for a simple and common divisibility rule, such as divisibility by 4, which can be tested quickly from the last two digits of the number. Final Answer: The number which is different from the others in the group is 290.

Question 10

Three of the following four letter groups follow a similar alphabetical pattern. Choose the group that does not follow this pattern.

Introduction / Context: This is another letter sequence classification question. You are given several three letter groups and asked to find which one does not follow the same pattern as the others. Recognising patterns based on alphabetical positions and consistent differences is the key to solving such problems. Given Data / Assumptions: The letter groups are EBA, XUT, TQP, JFE and RPN. Each group consists of three letters written in uppercase. We use the standard alphabetical positions: A=1, B=2, C=3, ..., Z=26. We expect a consistent pattern in the differences between consecutive letters in the group. Concept / Approach: A common structure in such puzzles is that the letters move backwards or forwards by a fixed number of positions. By converting each letter to its numeric position and calculating the differences between the first and second letters, and between the second and third letters, we can see whether the pattern is consistent across groups. The group that breaks the numeric pattern will be the odd one out. Step-by-Step Solution: Step 1: Write the alphabet positions of the letters.EBA: E=5, B=2, A=1.XUT: X=24, U=21, T=20.TQP: T=20, Q=17, P=16.JFE: J=10, F=6, E=5.RPN: R=18, P=16, N=14 (extra distractor).Step 2: Compute the differences between the first and second letters, and between the second and third letters.For EBA: 5 → 2 is a difference of 3; 2 → 1 is a difference of 1.For XUT: 24 → 21 is a difference of 3; 21 → 20 is a difference of 1.For TQP: 20 → 17 is a difference of 3; 17 → 16 is a difference of 1.For JFE: 10 → 6 is a difference of 4; 6 → 5 is a difference of 1.For RPN: 18 → 16 is a difference of 2; 16 → 14 is a difference of 2 (this is a filler for extended practice).Step 3: Observe the pattern. In EBA, XUT and TQP, the first letter goes back by 3 positions to the second, and then the second goes back by 1 position to the third.Step 4: In JFE, the first letter J (10) goes back by 4 positions to F (6), not 3. Then F goes back by 1 position to E, which matches the second part but not the first.Step 5: Within the original four options, EBA, XUT and TQP share the consistent \"−3, −1\" pattern, while JFE follows \"−4, −1\".Step 6: Therefore, JFE does not follow the same alphabetical difference pattern and is the odd one out. Verification / Alternative check: You can verify quickly by just checking the difference between the first and second letters. E to B is 3 steps backward (E, D, C, B). X to U is also 3 steps backward (X, W, V, U). T to Q is again 3 steps backward. But J to F is 4 steps backward (J, I, H, G, F). This fast check already shows that JFE does not follow the same step size as the other groups. Why Other Options Are Wrong: EBA, XUT and TQP form a clear group based on the same consistent pattern of letter spacing. They all follow the \"minus 3 then minus 1\" structure inside the three letter group. RPN is an extra practice option and not part of the original comparison. Within the original four options, only JFE breaks the pattern, so the other three are not the odd one out. Common Pitfalls: Some candidates mistakenly focus on the third letters alone or look for patterns involving the sum of positions rather than the simpler step differences. Another error is to consider the filler option and get confused. In exam questions, the main goal is to compare the original answer choices and look for the simplest consistent rule. Always convert letters to numbers and compute step differences to reveal hidden patterns efficiently. Final Answer: The letter group that does not belong to the pattern is JFE.

Question 11

Four of the following names are of great religious or spiritual teachers and reformers. Choose the one name that does not belong with the others.

Accepted Answer

Introduction / Context: This is a general knowledge based classification question. It involves famous historical figures and asks you to pick the one whose primary role is different from that of the others. The focus here is on religious and spiritual founders as compared to a mainly political leader. Given Data / Assumptions: Nanak (Guru Nanak), the founder of Sikhism. Christ (Jesus Christ), central figure of Christianity. Buddha (Gautama Buddha), founder of Buddhism. Gandhi (Mahatma Gandhi), leader of the Indian freedom movement. Mahavira, the key teacher associated with Jainism (added as an additional similar figure). We focus on their primary and most recognised roles in history. Concept / Approach: The question can be solved by categorising these figures based on whether they are primarily remembered as founders or central spiritual leaders of major religions, or as political and social reformers without founding a new religion. If four of the names clearly belong to the first category and one belongs mainly to the second category, that one is the odd one out. Step-by-Step Solution: Step 1: Guru Nanak is widely known as the founder and first Guru of Sikhism, a major world religion.Step 2: Jesus Christ is the central figure and saviour in Christianity, which developed around his life and teachings.Step 3: Gautama Buddha is recognised as the founder of Buddhism, another major world religion focused on his teachings about suffering and enlightenment.Step 4: Mahavira is the most prominent teacher in Jainism and is commonly associated with shaping the religion in its present form. He is revered as a Tirthankara.Step 5: Mahatma Gandhi, on the other hand, is primarily known as the political and moral leader of the Indian independence movement against colonial rule. His philosophy of non violence and truth had a strong spiritual dimension, but he did not found a new religion.Step 6: Therefore, four names (Nanak, Christ, Buddha, Mahavira) are directly linked to religious founding or central spiritual roles, while Gandhi is mainly a political and national leader.Step 7: Thus, Gandhi is the one who does not belong to the group of religious founders and is the odd one out. Verification / Alternative check: Ask which of these names is associated with a formal religion named after or directly built around their teachings. Sikhism is associated with Guru Nanak, Christianity with Christ, Buddhism with Buddha and Jainism with Mahavira. There is no separate organised religion named after Gandhi in the same way; instead, he inspired political movements and moral thought. This simple test clearly distinguishes Gandhi from the others. Why Other Options Are Wrong: Nanak, Christ, Buddha and Mahavira all hold central positions in major religious traditions. They are venerated as spiritual guides, prophets or enlightened beings. Their primary legacy is religious and spiritual. Because they share this common role, they form a natural group and cannot be considered the odd ones out in this context. Common Pitfalls: Some learners may be confused by the fact that Gandhi was also deeply spiritual and used religious ideas in his political work. However, the question is asking about the main category of contribution, not whether someone was personally religious. The key difference is that Gandhi did not establish a distinct religion or become its central divine or enlightened figure. Focusing on that distinction leads to the correct answer. Final Answer: The name that does not belong with the others is Gandhi.

Question 12

Three of the following four are spices, and hence form a group. Which one does not belong to this group?

Accepted Answer

Introduction / Context: This is a classification question based on everyday knowledge of food items. You are given names of items commonly found in a kitchen or market and must identify which one is not like the others. Specifically, the focus is on spices versus fruits. Given Data / Assumptions: Clove, a dried flower bud used as a spice. Cinnamon, a bark used as a spice. Pepper, usually black peppercorn, used as a spice. Apricot, an edible fruit. Cardamom, an aromatic seed spice (added as an extra spice example). We assume common culinary usage of these items. Concept / Approach: The straightforward way to solve this is to classify each item according to its primary culinary category. If several items are spices used in small quantities to flavour food, and one item is mainly a fruit eaten as a food item in itself, the fruit will be the odd one out. Spices are aromatic and used for seasoning, while fruits are eaten for their flesh and sweetness or tanginess. Step-by-Step Solution: Step 1: Clove is a well known spice. It is the dried flower bud of a tree and is used to flavour dishes, teas and sweets.Step 2: Cinnamon is another common spice obtained from the inner bark of certain trees. It is widely used for its distinct aroma and flavour in both sweet and savoury recipes.Step 3: Pepper, especially black pepper, is the dried fruit of the pepper plant and is used as a spice to add heat and flavour to food.Step 4: Cardamom, included as an extra example, is a seed spice used for its strong aroma in many cuisines.Step 5: Apricot, in contrast, is a soft, fleshy fruit. It is eaten fresh or dried as a fruit, used in jams or desserts, and is not classified as a spice.Step 6: The main culinary distinction is that clove, cinnamon, pepper and cardamom are primarily used as flavouring agents in small quantities, while apricot is eaten as a fruit in larger portions.Step 7: Therefore, three of the original four items are spices, and apricot is the one that does not belong to this group. Verification / Alternative check: Imagine how each item is sold in a market. Clove, cinnamon, pepper and cardamom appear in the spice section, usually in small packets or jars. Apricot appears in the fruits and dry fruits section as a whole food. When preparing a dish, you usually sprinkle or add a pinch of cloves, cinnamon or pepper, but you may eat an entire apricot as a snack. This difference in usage confirms the classification. Why Other Options Are Wrong: Clove, cinnamon and pepper clearly belong to the spice category, and cardamom would fit there as well. They share common properties of being aromatic, concentrated in flavour and used mainly for seasoning. Because they all belong to the same culinary category, none of them can be the odd one out in this question. Apricot is the only fruit among them. Common Pitfalls: Sometimes learners may overthink and consider botanical details, such as whether pepper is technically a fruit. However, in everyday culinary classification, pepper is treated as a spice. The question is testing simple everyday knowledge, not advanced botany. Stick to how these items are used in cooking, and the pattern becomes clear. Final Answer: The item which does not belong with the others is Apricot.

Question 13

Choose the number which is different from the others in the group based on a basic numerical property.

Accepted Answer

Introduction / Context: This question asks you to identify which number is different from the others in a simple numerical sense. Many such classification questions are built around well known properties like being a prime number, being divisible by 3, or being a perfect square. Given Data / Assumptions: The given numbers are 183, 137, 121, 231 and 169. We assume basic knowledge of prime numbers and perfect squares. We are looking for a property shared by three of the original four numbers but not the remaining one. Concept / Approach: A quick way to spot differences is to check whether any of the numbers is a perfect square, since perfect squares are visually distinctive. Alternatively, we can test divisibility by small prime numbers like 2, 3, 5, 7 or 11, and check for prime numbers. The number that has a unique status, such as being a perfect square while others are not, will be the odd one out. Step-by-Step Solution: Step 1: Check 121. 11 * 11 = 121, so 121 is a perfect square.Step 2: Check 169 (the extra practice option). 13 * 13 = 169, so 169 is also a perfect square, but it is not part of the original four way comparison.Step 3: Now look at 137. Try small divisors. 137 is not divisible by 2, 3, 5, 7 or 11. In fact, 137 is a prime number.Step 4: Check 183. 183 ÷ 3 = 61, so 183 is composite and not a perfect square.Step 5: Check 231. 231 ÷ 3 = 77, and 77 ÷ 7 = 11, so 231 = 3 * 7 * 11. It is also composite and not a perfect square.Step 6: Among the original four numbers (183, 137, 121, 231), only 121 is a perfect square, whereas the others are not.Step 7: Being a perfect square is a strong distinguishing property, so 121 is numerically different from the others. Verification / Alternative check: To verify, write down nearby squares. 10^2 = 100 and 11^2 = 121, 12^2 = 144. So 121 clearly fits exactly as 11^2. Now check if 183 or 231 come close to any perfect squares. 13^2 = 169 and 14^2 = 196; 183 is between these two and not equal to either. 15^2 = 225 and 16^2 = 256; 231 is between these and again not a square. 137 lies between 11^2 (121) and 12^2 (144), but is not equal to a perfect square. Thus 121 stands out. Why Other Options Are Wrong: 183 and 231 are composite numbers and share no special simple property like being a perfect square. 137 is prime, which is a notable property, but in this particular set, the question clearly targets the perfect square property of 121 because it is much more obvious and typical in such classification questions. Therefore, 183, 137 and 231 are all non square numbers, while 121 alone is a perfect square. Common Pitfalls: Some learners may be tempted to pick the prime number 137 as the odd one out. However, exam oriented classification questions often prefer the more visibly recognisable property, such as being a perfect square, rather than the more hidden property of primality. Always consider what property is simplest and most likely intended by question setters. Final Answer: The number which is different from the others in the group is 121.

Question 14

Choose the pair in which the relationship between the two words is different from that in the other pairs.

Accepted Answer

Introduction / Context: This question examines your understanding of the typical relationships between animals (or beings) and the places where they are kept or housed. You must identify which pair does not match the pattern followed by the others. Given Data / Assumptions: Man : Garage. Cow : Shed. Pig : Sty. Horse : Stable. Dog : Kennel. We assume normal meanings: a cow lives in a shed, a pig in a sty, a horse in a stable and a dog in a kennel. Concept / Approach: The majority of pairs clearly connect an animal with the name of its shelter or living place. To find the odd one out, we look for a pair where the second word is not naturally used as the shelter of the first. If four pairs form correct \"animal and its dwelling\" combinations and one pair does not, that incorrect or unusual pair is the differently related one. Step-by-Step Solution: Step 1: Cow : Shed is a standard pairing. Cows and other cattle are usually kept in a cowshed or cattle shed.Step 2: Pig : Sty is also a standard pairing. A sty is the enclosure or pen where pigs are housed.Step 3: Horse : Stable is another correct pairing. Horses are typically kept in stables.Step 4: Dog : Kennel is also correct. A kennel is a small shelter or cage where a dog is kept.Step 5: Now consider Man : Garage. A garage is primarily a place to keep vehicles such as cars or motorcycles, not a place where a person lives.Step 6: The natural dwelling of a person is a house, flat or home, not a garage. While a person can enter a garage, the relationship is not of \"being housed\" in the same sense.Step 7: Therefore, Cow : Shed, Pig : Sty, Horse : Stable and Dog : Kennel are all correct animal–shelter pairs, whereas Man : Garage does not fit this pattern.Step 8: Man : Garage is therefore the pair in which the relationship between the two words is different from the others. Verification / Alternative check: To verify, ask: \"If someone says this animal is in its [second word], does it sound normal?\" Saying \"the cow is in the shed\", \"the pig is in the sty\", \"the horse is in the stable\" and \"the dog is in the kennel\" all sound correct. Saying \"the man is in the garage\" is grammatically fine, but it does not express a dwelling relationship; it simply refers to a person being present in a storage place, not their home. Why Other Options Are Wrong: The other options all correctly pair animals with their usual dwellings. These pairings are standard and commonly used in both everyday language and exam questions. Because they share the same type of relationship, they form the majority pattern and cannot be considered the odd one out. Common Pitfalls: Some learners may overthink and consider that a garage is also a building, just like a shed or stable, and therefore treat it as similar. However, the key distinction is whether the building is meant as the principal dwelling of the creature in question. In typical usage, a garage is for vehicles, not for human residence, so the pairing is logically different. Final Answer: The pair that is differently related is Man : Garage.

Question 15

Among the following birds, choose the one which is least like the others in the group.

Accepted Answer

Introduction / Context: This general knowledge and classification question deals with common birds. Although all the options are birds, one of them belongs to a different ecological or behavioural category compared to the others. The task is to pick the bird which is least like the others. Given Data / Assumptions: Sparrow, a small seed eating bird often found in human surroundings. Parrot, a colourful bird, often herbivorous and sometimes kept as a pet. Swan, a large graceful water bird, mainly herbivorous, living around lakes and rivers. Vulture, a large bird of prey that feeds mostly on carrion (dead animals). Pigeon, a medium sized bird that eats grains and is common in cities. We assume basic knowledge of diet and behaviour of these birds. Concept / Approach: A natural way to classify birds is by their feeding habits and their roles in the ecosystem. Sparrows, parrots, swans and pigeons are generally not scavenging birds of prey. They mainly feed on seeds, grains, fruits or aquatic vegetation. Vultures, in contrast, are scavengers and birds of prey that primarily feed on dead animals. This ecological difference makes vultures stand out in the group. Step-by-Step Solution: Step 1: Sparrow is a small bird that usually eats seeds and small insects. It is not a predatory or scavenging bird of prey.Step 2: Parrot is generally herbivorous or omnivorous, feeding on fruits, seeds and nuts. It is not known as a bird of prey.Step 3: Swan feeds mainly on aquatic plants and small organisms in water bodies. It is not a scavenger; it is considered a waterfowl species.Step 4: Pigeon usually eats grains, seeds and food scraps. It may scavenge food in cities, but it is not a raptor or specialised scavenger.Step 5: Vulture, however, is a scavenging bird of prey. It feeds primarily on carrion and plays an important role in cleaning up carcasses in the environment.Step 6: Therefore, four of the birds (sparrow, parrot, swan, pigeon) are mostly seed eating or plant eating and are not classified as birds of prey, while vulture is a true scavenging raptor.Step 7: Because of its unique ecological role as a scavenger and bird of prey, vulture is least like the others. Verification / Alternative check: Another perspective is to look at beak shape and general appearance. Sparrows, parrots, swans and pigeons have beaks suited for pecking seeds, fruits or plants, whereas vultures have hooked beaks adapted for tearing flesh. This morphological difference reflects their different diets and further confirms that vultures belong to a different category. Why Other Options Are Wrong: Sparrow, parrot, swan and pigeon all belong to non raptorial bird groups and are mainly herbivorous or grain eating. They do not specialise in feeding on dead animals. Because they share similar non predatory feeding habits, they naturally form a group. None of them has the distinct scavenger role that vultures have in the ecosystem. Common Pitfalls: Some students might think that swan is different because it is a water bird, while the others are more land based. However, classification questions usually focus on more fundamental ecological roles rather than habitat alone. The clear distinction in diet and predatory behaviour between vulture and the other birds is a stronger and more standard exam pattern. Final Answer: The bird which is least like the others in the group is Vulture.

Question 16

Choose the pair in which the relationship between the two words is different from that in the other pairs.

Accepted Answer

Introduction / Context: This question tests your understanding of collective nouns and classification. You are given several pairs linking a living being to a word that describes a group of that being. One pair, however, uses a different or less standard type of collective expression. Your task is to identify that differently related pair. Given Data / Assumptions: Sheep : Flock. Bee : Swarm. Man : Mob. Cow : Herd. Wolf : Pack. We assume usual English usage of standard collective nouns for animals. Concept / Approach: Most of the pairs link an animal to the correct, neutral collective noun for a group of that animal, such as a flock of sheep or a herd of cows. The odd pair will be the one where the collective noun either is not the standard neutral term, or is used in a different, more emotional or negative sense rather than as a simple classification word. Step-by-Step Solution: Step 1: Sheep : Flock is a standard correct combination. A group of sheep is called a flock of sheep.Step 2: Bee : Swarm is correct. A group of bees is typically called a swarm, especially when they move together in the air.Step 3: Cow : Herd is also standard. Many cows together form a herd of cattle.Step 4: Wolf : Pack is a correct animal–collective noun pairing. A group of wolves is known as a pack.Step 5: Now consider Man : Mob. While the word mob can refer to a large, disorderly crowd of people, it is not the neutral or standard collective noun for humans as a species.Step 6: The neutral collective words for groups of humans are crowd, group, community or population. Mob has a negative connotation, suggesting rowdiness or violence.Step 7: Sheep : Flock, Bee : Swarm, Cow : Herd and Wolf : Pack are standard neutral animal collective pairings, whereas Man : Mob is not a standard neutral \"species : collective\" combination.Step 8: Therefore, Man : Mob is the pair that is differently related from the others. Verification / Alternative check: Try substituting the word \"group\" into each pair. \"A flock of sheep\" is correct; \"a swarm of bees\" is correct; \"a herd of cows\" is correct; \"a pack of wolves\" is correct. For humans, you would normally say \"a group of men\" or \"a crowd of people\". \"A mob of men\" is possible but carries a specific negative meaning instead of being the neutral standard, confirming that Man : Mob is not parallel to the other pairings. Why Other Options Are Wrong: Sheep : Flock, Bee : Swarm, Cow : Herd and Wolf : Pack all align a particular animal with its recognised collective noun. They are standard phrases in English and are often taught in school. Because they share the same type of relationship, they form a consistent group and cannot be considered differently related in this question. Common Pitfalls: Some learners may think that because a mob is still a group of humans, the pair must be acceptable. However, logical reasoning questions usually aim for the most typical and neutral relationships. The negative emotional tone of mob signals that Man : Mob is not parallel to the neutral collective nouns used for animals in the other options. Final Answer: The pair in which the words are differently related is Man : Mob.

Question 17

Among the following names of body parts, choose the one which is least like the others in the group.

Accepted Answer

Introduction / Context: This question is from the classification subsection of logical reasoning. All the options are parts of the human body, but one of them belongs to a different functional category compared to the others. Recognising how each part functions in relation to movement and support helps identify the odd one out. Given Data / Assumptions: Arm, a limb extending from the shoulder to the hand. Finger, one of the smaller movable parts at the end of the hand. Shoulder, the joint that connects the arm to the trunk. Foot, the lower extremity used for standing and walking. Hand, the terminal part of the arm used for grasping. We assume standard anatomical meanings of these terms. Concept / Approach: One useful way to classify these terms is to separate actual limbs or extremities from joints. Limbs and extremities such as arms, hands, fingers and feet are primarily used to perform actions like grasping or walking. A joint like the shoulder mainly functions as a connection and pivot point between the limb and the body. If most of the given words are limbs or parts of limbs and one is primarily a joint, that joint will be the odd one out. Step-by-Step Solution: Step 1: Arm is an upper limb. It is used for reaching, lifting, holding and many other actions, and it consists of bones, muscles and joints.Step 2: Finger is part of the hand, which itself is part of the upper limb. Fingers are used for grasping, touching and fine movements.Step 3: Foot is the terminal part of the lower limb. It supports the body weight and is used for standing, walking and running.Step 4: Hand is a distinct extremity at the end of the arm, used for grasping and manipulating objects.Step 5: Shoulder, in contrast, is a joint that connects the arm to the trunk of the body. It acts mainly as a pivot or attachment point rather than an extremity used directly for contact with the environment.Step 6: Thus, Arm, Finger, Foot and Hand are either limbs or terminal parts of limbs involved directly in performing actions, while Shoulder is primarily the joint where one of these limbs attaches to the body.Step 7: Therefore, Shoulder is functionally different and is the odd one out in the group. Verification / Alternative check: Another way to confirm the answer is to think of which parts actually touch and interact with external objects. You can touch and hold things with your hand and fingers, and you stand or walk using your feet. Your arm extends out and can itself come into contact with objects. The shoulder normally serves as an internal pivot and does not directly interact with objects in the same way. This supports the conclusion that Shoulder has a different functional role. Why Other Options Are Wrong: Arm, Finger, Foot and Hand are all actively used extremities or parts of extremities. They are not primarily joints; instead, they contain joints but also include bones, muscles and skin that directly interact with the outside world. Because of their similar role as active, external parts, they form a natural group and are not the odd one out. Common Pitfalls: Some learners may mistakenly think that Finger is the odd one out because it is smaller than the others or not an entire limb. However, size does not determine the classification here. The important distinction is between a joint (shoulder) and limb segments or extremities (arm, finger, foot, hand). Focusing on function and anatomical role instead of size leads to the correct answer. Final Answer: The body part which is least like the others is Shoulder.

Question 18

Choose the pair in which the relationship between the two words is different from that in the other pairs.

Accepted Answer

Introduction / Context: This is a classification question involving word pairs. In most options, you will notice a clear antonym (opposite meaning) relationship between the two words. One pair, however, does not show this kind of opposite relationship. Your task is to identify that differently related pair. Given Data / Assumptions: Lizard : Pad. Short : Long. Poor : Rich. Light : Heavy. Hot : Cold. We assume usual dictionary meanings of these words. Concept / Approach: The first step is to decide what type of relationship exists between the two words in each pair. For four of the pairs, the relationship is that of antonyms, where one word expresses the opposite quality of the other. The odd pair will be the one that does not show an opposite meaning, but some other type of vague or unclear connection instead. Step-by-Step Solution: Step 1: Consider \"Short : Long\". These are clearly opposite in meaning with respect to length or duration. If something is not short, it can be long, so they form an antonym pair.Step 2: Look at \"Poor : Rich\". These words are opposites in terms of wealth. Poor describes a lack of money or resources, while rich describes abundance of them.Step 3: Examine \"Light : Heavy\". These are opposite in relation to weight. An object that is light is easy to lift, while a heavy object is difficult to lift.Step 4: Check \"Hot : Cold\". These are opposites on the temperature scale. Hot implies high temperature, while cold implies low temperature.Step 5: Now examine \"Lizard : Pad\". Lizard is an animal, and pad could refer to a cushion, a writing pad or the pads on an animal foot, but the pair does not express a clear opposite or standard binary relationship.Step 6: Unlike the other four pairs, which present clear and direct opposites, Lizard and Pad cannot naturally be described as antonyms. They stand in no obvious opposite relation.Step 7: Therefore, \"Lizard : Pad\" is the only pair that does not follow the antonym pattern. Verification / Alternative check: To verify, try to insert the phrase \"is the opposite of\" between the two words in each pair. \"Short is the opposite of long\", \"Poor is the opposite of rich\", \"Light is the opposite of heavy\" and \"Hot is the opposite of cold\" all form perfectly correct sentences. But \"Lizard is the opposite of pad\" is meaningless and grammatically strange, confirming that this pair is not an antonym pair. Why Other Options Are Wrong: Short : Long, Poor : Rich, Light : Heavy and Hot : Cold are all standard pairs of opposite adjectives used in everyday language. They fit the same category of relationship. Because of that, they form the consistent group in this classification question and cannot be the odd one out. Common Pitfalls: Some learners may overthink the word pad and imagine special meanings, such as the adhesive pads on a lizard feet, but this is not a standard lexical relation used in reasoning tests. The exam expects recognition of clear antonym pairs, not obscure associations. If one pair obviously does not fit the pattern of opposites, that is almost always your answer. Final Answer: The pair in which the words are differently related is Lizard : Pad.

Question 19

In the following group of bedding-related items – sheet, pillow, cot and quilt – choose the one item that is different from the others, that is, the odd one out.

Accepted Answer

Introduction / Context: This verbal reasoning question tests your ability to classify everyday objects based on a common functional property and to identify the odd one out. Such questions are common in bank exams, SSC exams and other aptitude tests because they check whether you can quickly see patterns and group similar items together while isolating the item that does not fit the main category. Given Data / Assumptions: The four given items are: sheet, pillow, cot and quilt. All the items are associated with sleeping or resting arrangements in a household context. You must pick the item that is different in terms of broad category or functional type, not just a minor difference such as size or color. Treat everyday meanings of these words as used in normal English vocabulary questions. Concept / Approach: The core idea is to identify which items belong to the same functional group and which one belongs to a different group. In this question, three of the objects are soft bedding materials used on a bed, while one object is a piece of furniture that supports those bedding materials. Once you notice this distinction, the odd item becomes clear. Step-by-Step Solution: Step 1: List the items and recall what each one is used for in daily life. Step 2: A sheet is a large piece of cloth spread on a bed or used to cover a person. Step 3: A pillow is a soft cushion used to support the head while sleeping. Step 4: A quilt is a thick, padded covering used to keep the body warm while sleeping. Step 5: A cot is a light bed or bed frame used to lie on, often made of wood or metal, and other bedding items are placed on it. Step 6: Notice that sheet, pillow and quilt are all soft bedding articles, whereas a cot is the underlying piece of furniture. Step 7: Therefore, cot is the only item that belongs to the category “bed furniture” while the others are “bedding accessories”. Verification / Alternative check: Another way to verify is to ask: which of these items would usually be purchased from a furniture shop as a bed structure and which are bought as soft furnishings or bedding? Typically, cot is sold as furniture, while sheets, pillows and quilts are bought as bed linen or bedding. This confirms that cot stands apart from the rest. Why Other Options Are Wrong: Sheet: This is a soft bedding item, used on top of a mattress or to cover the body, so it belongs with pillow and quilt. Pillow: This is also a soft bedding accessory and not a piece of furniture, so it is similar to sheet and quilt, not the odd one out. Quilt: This is another soft bedding accessory used for warmth. It is not furniture, so it is part of the main bedding group. Common Pitfalls: A common mistake is to overthink subtle differences, such as which item covers the body or which is used seasonally. The exam expects you to focus on broad functional categories, not minor usage differences. Remember that classification questions rarely require very technical distinctions; they rely on everyday understanding of categories like furniture versus bedding accessories. Final Answer: The only furniture item among the given options, and therefore the odd one out, is Cot.

Question 20

The numbers 75, 85, 95 and 115 follow a particular numeric pattern. Three of these numbers are alike in a specific way and form a group. Which one of the four numbers does not belong to that group?

Accepted Answer

Introduction / Context: This logical reasoning question involves classification of numbers based on a hidden pattern. Such questions often appear in aptitude tests to check your comfort with number sequences and your ability to spot relationships among numbers quickly. Your task is to find which number among 75, 85, 95 and 115 does not fit a simple, consistent rule that connects the other three numbers. Given Data / Assumptions: The numbers provided are 75, 85, 95 and 115. All four numbers are positive, two-digit or three-digit integers and multiples of 5. Exactly three of these numbers should form a group based on a single clear numeric relation, and one number must be the odd one out. We assume that the intended pattern is simple and exam friendly, such as an arithmetic progression or another basic relationship. Concept / Approach: When dealing with number-classification questions, you should first check for basic patterns such as divisibility, arithmetic progression, geometric progression, or special properties like perfect squares or cubes. Since all four numbers are multiples of 5, divisibility alone will not separate them. A quick and powerful check is to see whether three of the four numbers lie in a regular sequence, leaving one that breaks the pattern. Step-by-Step Solution: Step 1: Arrange the numbers in ascending order: 75, 85, 95, 115. Step 2: Check the differences between consecutive numbers: 85 - 75 = 10, 95 - 85 = 10, 115 - 95 = 20. Step 3: Try forming an arithmetic progression from three numbers. Consider 75, 95 and 115. Step 4: Compute the differences in this subset: 95 - 75 = 20 and 115 - 95 = 20, so 75, 95 and 115 form an arithmetic progression with common difference 20. Step 5: Check whether 85 fits into this arithmetic progression. If we extend the sequence backwards or forwards using the same difference 20, we get 55, 75, 95, 115, 135 and so on. There is no place where 85 appears in this sequence. Step 6: Therefore, 75, 95 and 115 follow one simple rule – they are equally spaced by 20 – while 85 breaks this pattern. Verification / Alternative check: Another way to verify is to examine positions in the sequence starting at 75 with step 20. We can write the sequence as 75, 95, 115, 135 and so on. Each term is 75 plus a multiple of 20. Substituting 85 into the expression 75 + 20k, we would get 85 minus 75 equal to 10, which is not a multiple of 20. Hence 85 cannot be part of this particular arithmetic progression, confirming that it is the odd number out. Why Other Options Are Wrong: 75: It is the first term of the arithmetic progression 75, 95, 115, so it is part of the main group. 95: This is the second term in the same progression and fits the pattern perfectly. 115: This is the third term of the progression with common difference 20, so it clearly belongs to the group. Common Pitfalls: Many candidates get distracted by the fact that all numbers are multiples of 5 or look at divisibility by 3, 4 or 9. While these checks are sometimes useful, here they do not give a clean split where exactly three numbers share the property. Always check for simple sequences like equal differences or equal ratios, because exam setters frequently use arithmetic progressions in such questions. Final Answer: The only number that does not lie on the arithmetic progression with common difference 20 is 85.
