Question 1

Select the odd word from the given alternatives: Chair, Bench, Bed, and Sofa.

Accepted Answer

Introduction / Context: This odd one out question is based on everyday household furniture. It mixes items primarily used for sitting with an item primarily used for lying down or sleeping. Your task is to identify which item serves a distinctly different primary purpose. Such questions test practical knowledge of daily life objects and the ability to group them by function. Given Data / Assumptions: The words given are Chair, Bench, Bed, and Sofa. Chair, Bench, and Sofa are used mainly for sitting. Bed is primarily used for lying down and sleeping. The question expects categorisation by main function rather than material or appearance. Concept / Approach: The concept is to classify furniture based on whether it is designed for sitting or for sleeping. A chair is a seat for one person. A bench is a long seat for several people. A sofa is a padded seat for two or more persons. A bed, however, is specifically designed for lying down, resting, or sleeping. By grouping items according to their primary intended use, we can identify Bed as the one that does not fit with the rest. Step-by-Step Solution: Step 1: Consider Chair. It is a piece of furniture designed for one person to sit on. Step 2: Consider Bench. It is a long seat that allows several people to sit side by side. Step 3: Consider Sofa. It is a padded seat, often with cushions and armrests, used for sitting or lounging. Step 4: Consider Bed. It is a piece of furniture designed primarily for lying down, resting, and sleeping. Step 5: Group Chair, Bench, and Sofa together as seating furniture. Step 6: Observe that Bed does not belong to the seating group because its main function is to provide a sleeping surface. Step 7: Conclude that Bed is the odd word out among the four alternatives. Verification / Alternative check: To verify, imagine arranging furniture in a room. Chairs, benches, and sofas will be chosen when you want to seat guests or family members. Beds will be placed in bedrooms and are not generally used for normal sitting, even though people may occasionally sit on them. Another check is to ask which item is usually associated with sleep. Only Bed is primarily associated with sleeping, while Chair, Bench, and Sofa are associated with sitting. This confirms that Bed is the different item. Why Other Options Are Wrong: Chair is a typical seating furniture item and fits in the same category as Bench and Sofa, so it is not the odd one out. Bench is also designed mainly for sitting and belongs with Chair and Sofa. Sofa is again a seating item, even though it may also be used for lying down informally, its main category is seating furniture, so it is not the odd one. Common Pitfalls: Some students may overthink the problem and note that people sometimes lie on a sofa, which might lead them to confusion. However, the classification in reasoning questions is based on the primary, intended use of the furniture, not occasional behaviour. Another mistake is to focus on the size of the items instead of their function. While beds and sofas may both be large, their main purposes differ. To avoid these errors, always consider what the furniture is designed for in normal usage when grouping items. Final Answer: The odd word is Bed.

Question 2

Select the odd group of letters from the given alternatives: CEG, UXZ, ORT, and ILN.

Accepted Answer

Introduction / Context: This question involves recognising patterns in sequences of letters and identifying the odd group. Each option is a set of three letters, and the goal is to determine which group does not follow the same step pattern between letters as the others. Such letter sequence problems help evaluate your ability to handle alphabetical positions and simple arithmetic differences. Given Data / Assumptions: The letter groups are CEG, UXZ, ORT, and ILN. Each group seems to follow an increasing pattern from left to right. Three of these groups use the same sequence of steps between letters, while one group uses a different sequence. We use standard alphabetical positions: A = 1, B = 2, ..., Z = 26. Concept / Approach: The key concept is to write down the alphabetical position of each letter and compute the difference between consecutive letters in each group. Many such problems are designed so that three groups share one step pattern, for example +3 then +2, while one group has a different pattern, such as +2 then +2. By comparing these patterns, we can find the group that behaves differently and mark it as the odd one out. Step-by-Step Solution: Step 1: For CEG, positions are C = 3, E = 5, G = 7. Differences are 5 - 3 = 2 and 7 - 5 = 2, so the pattern is +2, +2. Step 2: For UXZ, positions are U = 21, X = 24, Z = 26. Differences are 24 - 21 = 3 and 26 - 24 = 2, so the pattern is +3, +2. Step 3: For ORT, positions are O = 15, R = 18, T = 20. Differences are 18 - 15 = 3 and 20 - 18 = 2, again +3, +2. Step 4: For ILN, positions are I = 9, L = 12, N = 14. Differences are 12 - 9 = 3 and 14 - 12 = 2, once more +3, +2. Step 5: Compare the patterns: UXZ, ORT, and ILN all share a +3, +2 progression. Step 6: CEG has a different progression of +2, +2 between its letters. Step 7: Therefore, CEG is the odd group of letters among the four options. Verification / Alternative check: You can use a mental check by counting the letters skipped between consecutive letters. In UXZ, there are two letters (V, W) between U and X, and one letter (Y) between X and Z. The same pattern holds for ORT, with two letters (P, Q) between O and R and one letter (S) between R and T, and for ILN, with two letters (J, K) between I and L and one (M) between L and N. In CEG, however, there is only one letter skipped between C and E (D) and one letter skipped between E and G (F). So CEG clearly uses equal jumps, unlike the others, confirming it as the odd group. Why Other Options Are Wrong: UXZ follows a +3, +2 letter movement pattern and matches ORT and ILN, so it is not the odd group. ORT also follows the same +3, +2 pattern and fits the main group. ILN again shows +3, +2 steps and belongs with UXZ and ORT, so it cannot be the different option. Common Pitfalls: A common mistake is to focus only on the exact letters used and not on the gaps between them. Since all groups appear to be increasing, you might overlook the difference in step size. Another error is miscounting positions near the end of the alphabet, especially for letters like X, Y, and Z. To avoid these issues, always convert letters into numbers and carefully compute the differences between each pair. Consistent practice with such problems will improve both speed and accuracy in letter sequence reasoning questions. Final Answer: The odd group of letters is CEG.

Question 3

In this aptitude classification question on textile materials, select the odd word from the given alternatives based on whether the fibre is natural or synthetic.

Accepted Answer

Introduction / Context: This verbal reasoning question tests your ability to classify everyday materials based on a common scientific property. The options are names of fibres or fabrics, and you must select the one that does not belong with the others. Such odd one out questions are common in aptitude exams because they quickly check basic general knowledge and logical grouping skills. Given Data / Assumptions: - The given words are Nylon, Wool, Silk, and Cotton.- All of them are widely used in clothing and textiles.- We assume a basic science classification of fibres into natural and synthetic types. Concept / Approach: The most natural way to classify these items is by origin. Textile fibres are broadly divided into natural fibres and synthetic or man made fibres. Natural fibres come from plants and animals. Synthetic fibres are produced chemically in factories. If three of the given options are natural and one is synthetic, then the synthetic one will be the odd word out. We will therefore identify which fibre is man made. Step-by-Step Solution: Step 1: Wool is a natural animal fibre obtained mainly from sheep.Step 2: Silk is another natural animal fibre produced by silkworms.Step 3: Cotton is a natural plant fibre obtained from cotton plants.Step 4: Nylon is a fully synthetic fibre created through chemical processes in factories.Step 5: Thus, three fibres are natural, and only one fibre is synthetic. Verification / Alternative check: You can also group the fibres as plant based or animal based plus man made. Cotton is plant based, wool and silk are animal based, and nylon clearly stands out as artificial. This confirms that nylon does not share the natural origin property. Why Other Options Are Wrong: Wool: Natural animal fibre, so it belongs with silk and cotton.Silk: Natural animal fibre, similar in category to wool.Cotton: Natural plant fibre widely used in textiles. Common Pitfalls: Some learners focus on how commonly each fabric is used or whether it is warm or cool to wear. The question, however, is about which word does not fit logically into the same category of fibre origin. Always think in terms of classification rule, not personal preference. Final Answer: The odd word is Nylon because it is a synthetic fibre while the others are natural fibres.

Question 4

In this alphabet pattern reasoning question, select the odd group of letters from the given alternatives based on the pattern of decreasing positions in the English alphabet.

Accepted Answer

Introduction / Context: This logical reasoning question involves letter group patterns from the English alphabet. Each option consists of three letters that appear to follow a sequence. Your task is to identify which letter group does not follow the same pattern as the others. Such problems strengthen observation of alphabetical order, direction, and constant steps between letters, which are frequently tested in competitive exams. Given Data / Assumptions: - The letter groups are ZXV, GDA, NKH, and URO.- All letters are uppercase English letters.- The pattern is likely related to the numerical positions of letters in the alphabet. Concept / Approach: The standard method for solving letter pattern questions is to convert letters to their alphabetical positions and then examine the differences between consecutive letters. When three groups show one consistent pattern and a single group shows a different pattern, that differing group is the odd one out. Here we will check whether the letters move backward by a fixed number of positions in the alphabet. Step-by-Step Solution: Step 1: For ZXV, positions are Z = 26, X = 24, V = 22. Differences are minus 2 and minus 2.Step 2: For GDA, positions are G = 7, D = 4, A = 1. Differences are minus 3 and minus 3.Step 3: For NKH, positions are N = 14, K = 11, H = 8. Differences are minus 3 and minus 3.Step 4: For URO, positions are U = 21, R = 18, O = 15. Differences are minus 3 and minus 3.Step 5: Three groups move back by 3 positions between each pair of letters, while one group moves back by only 2 positions. Verification / Alternative check: Say the groups aloud backward: G, D, A and N, K, H and U, R, O each step back three places. In contrast, Z, X, V step back only two places each. This confirms that the pattern in ZXV differs from the pattern in the other groups. Why Other Options Are Wrong: GDA: Follows a constant minus 3 sequence.NKH: Also follows a consistent minus 3 step.URO: Again decreases by 3 positions each time. Common Pitfalls: Sometimes students only check whether letters are in general descending order and miss the fact that the size of the step must be the same. Always compute the exact difference between positions to avoid such errors. Final Answer: The odd letter group is ZXV because it decreases by 2 positions between letters, while the other groups decrease by 3 positions.

Question 5

In this divisibility based number classification question, select the odd number from the given alternatives.

Accepted Answer

Introduction / Context: This quantitative aptitude question asks you to select the odd number from a group based on divisibility properties. These types of questions are very common in exams because they can be solved quickly using basic arithmetic and knowledge of multiples. The key is to identify a shared property among most numbers and then find the one that does not share that property. Given Data / Assumptions: - The options are 15, 20, 40, and 60.- All are positive integers of small size, which allows mental calculations.- We are looking for a number that does not fit a simple multiplicative pattern that the others share. Concept / Approach: A natural approach is to look for a common factor that divides three of the numbers. The numbers 20, 40, and 60 immediately suggest a pattern with 20 because 20 multiplied by 1, 2, and 3 gives 20, 40, and 60. If three numbers are multiples of 20 and one is not, that non multiple is the odd one out. We will confirm this pattern step by step. Step-by-Step Solution: Step 1: Check 20. It is clearly 1 * 20, so a multiple of 20.Step 2: Check 40. It is 2 * 20, again a multiple of 20.Step 3: Check 60. It is 3 * 20, so it also fits the multiples of 20 pattern, even though it has other factors as well.Step 4: Check 15. When you divide 15 by 20, you do not get a whole number, so 15 is not a multiple of 20.Step 5: Thus, three numbers can be expressed as k * 20 for integer k, and one cannot. Verification / Alternative check: You can list the first few multiples of 20: 20, 40, 60, 80, and so on. On that list you will see 20, 40, and 60 but never 15. This confirms that 15 is the only number that does not belong to the multiples of 20 group. Why Other Options Are Wrong: 20: Exactly equal to 1 * 20.40: Exactly equal to 2 * 20.60: Exactly equal to 3 * 20. Common Pitfalls: Many learners first check whether numbers are odd or even. Here, however, both 15 and 45 style numbers could be odd, but that is not the intended pattern. The cleaner rule is to look at a shared multiple, which naturally highlights 15 as different. Final Answer: The odd number is 15 because it is not a multiple of 20, whereas 20, 40, and 60 are multiples of 20.

Question 6

In this alphabetical series reasoning question, select the odd group of letters from the given alternatives based on whether the letters form a strictly decreasing sequence.

Accepted Answer

Introduction / Context: This question tests your ability to recognize patterns in letter sequences. Each option is a group of three letters, and you must decide which group does not follow the same alphabetical pattern as the others. Identifying increasing or decreasing sequences of consecutive letters is an important skill in verbal and non verbal reasoning sections of aptitude exams. Given Data / Assumptions: - The groups are MLN, FED, JIH, and RQP.- All letters are uppercase and belong to the English alphabet.- We assume that the pattern is based on the order and spacing of letters in the alphabet. Concept / Approach: The usual approach is to convert each letter into its numeric position and then check how the sequence moves from left to right. If three groups are strictly decreasing sequences with equal steps, and one group breaks that rule, the group that breaks it is the odd one out. Decreasing sequences are particularly common in such questions, so we focus on that possibility first. Step-by-Step Solution: Step 1: For FED, positions are F = 6, E = 5, D = 4. This is a consecutive decreasing sequence with step minus 1 between letters.Step 2: For JIH, positions are J = 10, I = 9, H = 8. Again, a consecutive decreasing pattern with step minus 1.Step 3: For RQP, positions are R = 18, Q = 17, P = 16. This is also a strictly decreasing consecutive sequence with step minus 1.Step 4: For MLN, positions are M = 13, L = 12, N = 14. The sequence goes down from M to L but then jumps up from L to N, so it is not strictly decreasing.Step 5: Therefore, three groups form neat backward sequences, while MLN does not. Verification / Alternative check: Recite the groups aloud backward. FED, JIH, and RQP sound like small segments of the alphabet spoken in reverse order. MLN does not match this pattern because the letters are not in a continuous reverse run. Why Other Options Are Wrong: FED: Correct backward sequence, so it fits the pattern.JIH: Also a correct backward three letter run.RQP: Another backward consecutive sequence. Common Pitfalls: Some students focus only on whether the letters look like they belong together and overlook the exact ordering. Always check if the movement between letters is consistent, especially when dealing with sequences. Final Answer: The odd letter group is MLN because it is not a strictly decreasing consecutive sequence, unlike the other three groups.

Question 7

In this number classification question on perfect squares, select the odd number from the given alternatives.

Accepted Answer

Introduction / Context: This quantitative aptitude question focuses on perfect squares and requires you to identify the odd number in the list. Perfect power recognition, especially for square numbers, is a common theme in competitive exams. Here, you must decide which number does not belong to the group when the others share the property of being perfect squares of integers. Given Data / Assumptions: - The given numbers are 1600, 2500, 3600, and 4000.- All are four digit positive integers.- The likely pattern is whether each number can be written as n^2 for some integer n. Concept / Approach: A perfect square is any number that can be expressed as n^2 where n is an integer. Many exam questions use round figures like 40^2, 50^2, and 60^2 because they are easy to recognize. The strategy is to test each number to see whether its square root is an integer. The number that fails this test is the odd one out. Step-by-Step Solution: Step 1: 1600 can be written as 40^2, so it is a perfect square.Step 2: 2500 can be written as 50^2, so it is also a perfect square.Step 3: 3600 can be written as 60^2, again a perfect square.Step 4: 4000 has a square root between 63 and 64 but not equal to any integer, so it is not a perfect square.Step 5: Therefore, three numbers are perfect squares of whole numbers, and one is not. Verification / Alternative check: You can factor 4000 as 4000 = 400 * 10 = 20^2 * 10. Because there is an extra factor of 10 that does not form a complete square, 4000 cannot be expressed as n^2 for an integer n. This confirms that it is not a perfect square. Why Other Options Are Wrong: 1600: Equal to 40^2 and so it fits the pattern.2500: Equal to 50^2 and belongs with the others.3600: Equal to 60^2 and also a perfect square. Common Pitfalls: Students sometimes guess based on the visual size of the number rather than checking square roots or factorization. Always confirm whether the square root is an integer before deciding if a number is a perfect square. Final Answer: The odd number is 4000 because it is not a perfect square, while 1600, 2500, and 3600 are perfect squares.

Question 8

In this classification question on food items, select the odd word from the given alternatives based on whether it is a nut or a fruit.

Accepted Answer

Introduction / Context: This general knowledge based reasoning question asks you to select the odd word from a list of food items. All the options look like dry fruits or snacks, but one of them belongs to a different botanical category from the others. Being able to classify common foods such as nuts and fruits is a simple but effective test of reasoning and awareness. Given Data / Assumptions: - The options are Almond, Dates, Walnut, and Cashew.- These are all commonly eaten as snacks or used in sweets and desserts.- We classify items based on whether they are tree nuts or fruits. Concept / Approach: Most aptitude questions of this form group together items which are of the same type and include one item that is different by origin or botanical nature. Almond, walnut, and cashew are typically treated as nuts, while dates are actually fruits that grow on date palm trees. Therefore, we check which option is not a nut like the others. Step-by-Step Solution: Step 1: Almond is considered a tree nut, widely used in dry fruit mixes.Step 2: Walnut is another tree nut, known for its shell and brain shaped kernel.Step 3: Cashew is also a nut, used in cooking and snacks.Step 4: Dates are sweet fleshy fruits that grow in clusters on date palm trees. They are not nuts.Step 5: Thus, three options belong to the nut group, while one option is a fruit. Verification / Alternative check: You can imagine a mixed dry fruit packet. Almonds, walnuts, and cashews are standard nut ingredients. Dates are often added separately as a fruit component and are clearly different in texture and structure. Why Other Options Are Wrong: Almond: A nut, so it fits with walnut and cashew.Walnut: Also a nut and member of the same category.Cashew: Again a nut used similarly to almonds and walnuts. Common Pitfalls: Many learners get confused because in daily speech all of these are loosely called dry fruits. However, for reasoning questions the classification is often based on the exact type, so you must remember that dates are fruits, not nuts. Final Answer: The odd word is Dates because it is a fruit, whereas almond, walnut, and cashew are nuts.

Question 9

In this number theory reasoning question, select the odd number from the given alternatives based on whether it is prime or composite.

Accepted Answer

Introduction / Context: This quantitative aptitude question is based on the concept of prime and composite numbers. You are asked to identify which number in the list does not share the same primality property as the others. Recognizing prime numbers is a core skill in number theory and is frequently checked in reasoning and aptitude tests. Given Data / Assumptions: - The four numbers given are 23, 29, 37, and 33.- All are two digit positive integers.- The test is to see which numbers are prime and which are composite. Concept / Approach: A prime number has exactly two distinct positive divisors, 1 and the number itself. A composite number has more than two divisors. The strategy is to check each option for divisibility by small primes such as 2, 3, 5, and 7. If three numbers are prime and one is composite, the composite number will be the odd one out. Step-by-Step Solution: Step 1: Check 23. It is not divisible by 2, 3, or 5. It has factors only 1 and 23, so 23 is prime.Step 2: Check 29. It is not divisible by 2, 3, or 5. It has factors only 1 and 29, so 29 is prime.Step 3: Check 37. It is not divisible by 2, 3, or 5. It has only 1 and 37 as factors, so 37 is prime.Step 4: Check 33. It is divisible by 3 because 3 * 11 = 33. Therefore, 33 has more than two factors and is composite.Step 5: Hence, three options are prime numbers, while one option is composite. Verification / Alternative check: You can use the digit sum method to quickly test divisibility by 3. The digit sum of 33 is 3 + 3 = 6, which is a multiple of 3, so 33 is divisible by 3 and is composite. The digit sums of 23, 29, and 37 are 5, 11, and 10, none of which are multiples of 3, so they remain candidates for primes. Why Other Options Are Wrong: 23: Prime number, so it belongs with 29 and 37.29: Also a prime number.37: Again, a prime number. Common Pitfalls: Some students may think any number ending with 3 is prime, but this is not always true. For example, 33 and 63 are composite. Always confirm with divisibility tests instead of relying only on the last digit. Final Answer: The odd number is 33 because it is composite, while 23, 29, and 37 are prime numbers.

Question 10

In this letter series question, select the odd group of letters from the given alternatives based on the pattern formed by pairs of letters.

Accepted Answer

Introduction / Context: This is a letter pattern reasoning question where each option is a group of four letters. The task is to identify the group that does not follow the same alphabetic rule as the others. Such problems are common in non verbal reasoning sections and strengthen a candidate's ability to observe structured patterns in sequences. Given Data / Assumptions: - The letter groups are IMOR, ORIL, UXCF, and ADWZ.- Letters are taken from the English alphabet and appear in pairs inside each group.- The pattern is likely based on fixed jumps between specific pairs of letters. Concept / Approach: A helpful approach is to look at each four letter group as two distinct pairs: first two letters and last two letters. Then we can check the difference in alphabetical positions within each pair. If three groups show the same constant difference in both pairs and one does not, the non matching group is the odd one out. Step-by-Step Solution: Step 1: For ORIL, consider pairs (O, R) and (I, L). O is the 15th letter, R is 18th, so the difference is plus 3. I is the 9th letter, L is 12th, again a difference of plus 3.Step 2: For UXCF, consider pairs (U, X) and (C, F). U is 21st and X is 24th, difference plus 3. C is 3rd and F is 6th, also difference plus 3.Step 3: For ADWZ, consider pairs (A, D) and (W, Z). A is 1st and D is 4th, difference plus 3. W is 23rd and Z is 26th, again plus 3.Step 4: For IMOR, consider pairs (I, M) and (O, R). I is 9th and M is 13th, difference plus 4. O is 15th and R is 18th, difference plus 3. The two pairs do not share the same step size.Step 5: Therefore, three groups maintain a consistent gap of plus 3 in both pairs, while one group has mismatched gaps. Verification / Alternative check: You can quickly note that ORIL, UXCF, and ADWZ are formed by taking one letter and then jumping exactly three places ahead to get the next in each pair. IMOR breaks this rule with a jump of four followed by a jump of three. Why Other Options Are Wrong: ORIL: Both pairs increase by three positions.UXCF: Again increases by three in each pair.ADWZ: Follows the same plus three rule for both pairs. Common Pitfalls: Some candidates try to see a single continuous pattern across all four letters instead of separating them into pairs. For this question, treating each pair independently makes the hidden structure much clearer. Final Answer: The odd letter group is IMOR because it does not maintain the same alphabetical step size in both of its pairs, unlike the other groups.

Question 11

In this geometry based classification question, select the odd word from the given alternatives related to sides and measures in plane figures.

Accepted Answer

Introduction / Context: This reasoning question is rooted in basic geometry and asks you to select the odd word from the given list. Three of the options are strongly related to the sides of a right angled triangle, while one is a term used in the context of circles. Such classification questions check conceptual clarity about geometric terms rather than calculations. Given Data / Assumptions: - The options are Perpendicular, Base, Hypotenuse, and Radius.- All four terms are used in school level geometry.- We assume standard definitions for triangle and circle related terminology. Concept / Approach: In a right angled triangle, the three sides are commonly described as base, perpendicular, and hypotenuse. The term radius, however, refers to the distance from the centre of a circle to a point on its circumference. A simple classification is therefore possible: three options belong to the right triangle family, and one belongs to the circle family. The circle related term is the odd one out. Step-by-Step Solution: Step 1: Base is the side of a triangle that is usually taken as the reference side for height.Step 2: Perpendicular is the side that forms a right angle with the base in a right angled triangle.Step 3: Hypotenuse is the side opposite the right angle and is the longest side of a right angled triangle.Step 4: Radius is a line segment drawn from the centre of a circle to any point on the circle. It is not a side of a triangle.Step 5: Three of the terms are names for sides of a right angled triangle, while one is not. Verification / Alternative check: You can picture a right angled triangle and label its sides. You will easily find base, perpendicular, and hypotenuse, but there is no side called radius. Conversely, drawing a circle immediately suggests the radius but not base or hypotenuse. This visual check confirms the classification. Why Other Options Are Wrong: Perpendicular: One of the legs of a right angled triangle.Base: Another side of the triangle used along with the perpendicular.Hypotenuse: The third side of the right angled triangle. Common Pitfalls: Students sometimes overcomplicate by thinking about formulae like area or Pythagoras theorem. The question only needs identification of which term belongs to a circle instead of a triangle. Keeping focus on the basic definitions makes the problem easy. Final Answer: The odd word is Radius because it is a circle related term, whereas the other three describe sides of a right angled triangle.

Question 12

In this alphabet pattern question on letter pairs, select the odd pair from the given alternatives based on constant jumps in the alphabet.

Accepted Answer

Introduction / Context: This reasoning question deals with pairs of letters from the English alphabet. You are asked to identify the odd pair that does not follow the same jump pattern between the two letters. Recognizing fixed differences between alphabet positions is a very standard skill tested in series and coding decoding questions in competitive exams. Given Data / Assumptions: - The letter pairs are FJ, KO, RV, and WZ.- All letters are uppercase.- We assume that the rule is based on numerical positions of letters in the alphabet. Concept / Approach: The usual approach is to convert each letter into its alphabet position and then calculate the difference between the first and second letters in each pair. If three pairs have the same difference and one pair has a different difference, the distinct pair is the odd one out. This method eliminates guesswork and provides a clear numeric pattern. Step-by-Step Solution: Step 1: In FJ, F is the 6th letter and J is the 10th letter. The difference is 10 minus 6 which equals 4.Step 2: In KO, K is the 11th letter and O is the 15th letter. The difference is 4 again.Step 3: In RV, R is the 18th letter and V is the 22nd letter. The difference is also 4.Step 4: In WZ, W is the 23rd letter and Z is the 26th letter. The difference here is 3, not 4.Step 5: Thus, three pairs share a constant jump of plus 4, while one pair has a jump of plus 3. Verification / Alternative check: Say the alphabet sequence aloud: F, G, H, I, J spans four steps; K, L, M, N, O spans four steps; R, S, T, U, V spans four steps. However, W, X, Y, Z has only three steps from W to Z. This oral check confirms the numeric observation. Why Other Options Are Wrong: FJ: F to J represents a forward jump of four letters.KO: K to O is also a forward jump of four letters.RV: R to V maintains the same forward jump of four letters. Common Pitfalls: Some candidates only notice that all pairs are ascending and stop there. The crucial point is not just the direction, but also that the exact step size should match, so you must calculate the numerical difference. Final Answer: The odd letter pair is WZ because it has a jump of three letters, while the other pairs have a jump of four letters between their letters.

Question 13

In this three digit number reasoning question, select the odd number from the given alternatives based on the relationship between its digits.

Accepted Answer

Introduction / Context: This question tests your ability to detect internal digit relationships in three digit numbers. Each option is a three digit number, and you must pick the number that does not follow the same internal rule as the others. Such digit based patterns are frequently tested in aptitude exams because they encourage careful observation rather than direct calculation of large expressions. Given Data / Assumptions: - The options are 325, 437, 246, and 564.- Each number has three digits that may be related through simple arithmetic operations.- A common pattern is that the third digit is obtained from the first two digits. Concept / Approach: One classic pattern with three digit numbers is that the third digit equals the sum of the first two digits. If three numbers satisfy this rule and one does not, that non matching number is the odd one out. We will therefore check each number to see whether the sum of the first two digits equals the third digit. Step-by-Step Solution: Step 1: For 325, add the first two digits: 3 + 2 = 5. This matches the third digit, so 325 follows the rule.Step 2: For 437, add 4 + 3 = 7. This equals the third digit, so 437 also follows the rule.Step 3: For 246, add 2 + 4 = 6. This matches the third digit, so 246 follows the same pattern.Step 4: For 564, add 5 + 6 = 11, which does not equal the third digit 4. So 564 does not follow the sum pattern.Step 5: Therefore, three numbers satisfy the rule third digit = sum of first two digits, while one number does not. Verification / Alternative check: You can quickly verify by checking whether subtracting the second digit from the third gives the first digit. For 325, 5 minus 2 equals 3; for 437, 7 minus 3 equals 4; for 246, 6 minus 4 equals 2. For 564, 4 minus 6 equals minus 2, which does not match the first digit 5. This confirms that 564 is the odd one. Why Other Options Are Wrong: 325: Correctly follows third digit = sum of first two digits.437: Also follows the same relationship.246: Again matches the sum relationship. Common Pitfalls: Many candidates look only at even or odd digits and miss the more meaningful sum rule. Always check simple arithmetic relations between digits when you see patterns in three digit numbers. Final Answer: The odd number is 564 because its third digit is not equal to the sum of its first two digits, unlike the other three numbers.

Question 14

In this number classification question, select the odd number from the given alternatives based on divisibility by 3.

Accepted Answer

Introduction / Context: This quantitative aptitude question asks you to choose the odd number from four given options using basic divisibility rules. The key idea is to recognize a property that three numbers share and one does not. Here, divisibility by 3 is a very natural property to test because the numbers are small and their digit sums are easy to compute mentally. Given Data / Assumptions: - The numbers are 192, 240, 141, and 173.- All four numbers are positive integers.- We will focus on simple divisibility rules, especially divisibility by 3. Concept / Approach: The divisibility rule for 3 states that a number is divisible by 3 if the sum of its digits is a multiple of 3. This rule is quick to apply and avoids direct division. If three numbers pass this test and one fails, the failing number is the odd one out. We will apply this rule to each option in turn. Step-by-Step Solution: Step 1: For 192, the digit sum is 1 + 9 + 2 = 12. Twelve is a multiple of 3, so 192 is divisible by 3.Step 2: For 240, the digit sum is 2 + 4 + 0 = 6. Six is a multiple of 3, so 240 is divisible by 3.Step 3: For 141, the digit sum is 1 + 4 + 1 = 6. This is also a multiple of 3, so 141 is divisible by 3.Step 4: For 173, the digit sum is 1 + 7 + 3 = 11, which is not a multiple of 3. Therefore, 173 is not divisible by 3.Step 5: Three numbers are divisible by 3, while one is not. Verification / Alternative check: You can check directly by dividing each number by 3. 192 divided by 3 gives 64, 240 divided by 3 gives 80, and 141 divided by 3 gives 47, all whole numbers. However, 173 divided by 3 gives a non integer result. This direct calculation supports the digit sum test. Why Other Options Are Wrong: 192: Multiple of 3, so it fits the main pattern.240: Also a multiple of 3 and belongs with 192 and 141.141: Again, divisible by 3 and not odd in this sense. Common Pitfalls: Candidates sometimes rely only on whether numbers are even or odd, but that is not the focus of this question. Here, both even and odd numbers can be divisible by 3, so you must apply the digit sum rule carefully. Final Answer: The odd number is 173 because it is not divisible by 3, unlike 192, 240, and 141 which are all multiples of 3.

Question 15

In this number pattern reasoning question, select the odd four digit number from the given alternatives based on divisibility by 8.

Accepted Answer

Introduction / Context: This question is designed to test your understanding of divisibility rules for larger numbers, especially divisibility by 8. You are given four four digit numbers and asked to identify the odd one out. Three of the numbers share a common divisibility property, while one does not. Such problems appear in quantitative aptitude tests to check speed and number sense. Given Data / Assumptions: - The options are 4416, 8432, 4520, and 4260.- All numbers are positive and four digit.- We will use the rule for divisibility by 8 as the main test. Concept / Approach: A number is divisible by 8 if its last three digits form a number that is divisible by 8. This rule works because 1000 is divisible by 8, so only the last three digits affect divisibility by 8. To solve this question efficiently, we examine the last three digits of each option and check whether those three digit numbers are multiples of 8. Step-by-Step Solution: Step 1: For 4416, the last three digits are 416. Because 416 divided by 8 equals 52, 4416 is divisible by 8.Step 2: For 8432, the last three digits are 432. Because 432 divided by 8 equals 54, 8432 is divisible by 8.Step 3: For 4520, the last three digits are 520. Because 520 divided by 8 equals 65, 4520 is divisible by 8.Step 4: For 4260, the last three digits are 260. Because 260 divided by 8 equals 32 remainder 4, 260 is not divisible by 8, so 4260 is not divisible by 8.Step 5: Therefore, three numbers are multiples of 8, while one number is not. Verification / Alternative check: You may also check using direct division. 4416 divided by 8, 8432 divided by 8, and 4520 divided by 8 all give whole numbers. However, 4260 divided by 8 produces a fraction, confirming that 4260 is not a multiple of 8. Why Other Options Are Wrong: 4416: Multiple of 8, so it fits the pattern.8432: Also divisible by 8 and belongs with 4416 and 4520.4520: Again, divisible by 8 and not the odd one. Common Pitfalls: Candidates sometimes test only divisibility by 2 or 4 and notice that all numbers are even, which does not help in distinguishing them. The key here is the stricter rule of divisibility by 8, which needs checking based on the last three digits. Final Answer: The odd number is 4260 because it is not divisible by 8, while 4416, 8432, and 4520 are all multiples of 8.

Question 16

In this sports based general knowledge classification question, select the odd name from the given alternatives.

Accepted Answer

Introduction / Context: This general knowledge reasoning question deals with famous Indian sportspersons. All four names belong to well known players, but three of them are associated with the same sport, while one is associated with a different sport. You must identify the odd name that does not fit with the others. Such questions test both sports awareness and classification skills. Given Data / Assumptions: - The names given are Dhanraj Pillay, Pankaj Advani, Dhyan Chand, and Sardara Singh.- All four are male Indian sportspersons.- We classify them by the main sport for which each is famous. Concept / Approach: The key idea is to recall the main sport connected with each person. Dhanraj Pillay, Dhyan Chand, and Sardara Singh are legendary or prominent players in Indian field hockey. Pankaj Advani, on the other hand, is a champion in cue sports such as billiards and snooker. Thus, three options come from hockey, and one from cue sports. The non hockey player is the odd one out. Step-by-Step Solution: Step 1: Dhanraj Pillay is a famous Indian hockey player who captained the national team.Step 2: Dhyan Chand is widely regarded as one of the greatest hockey players in history and is often called the hockey wizard.Step 3: Sardara Singh is also a well known Indian field hockey player and former captain.Step 4: Pankaj Advani is a world champion in billiards and snooker, which are indoor cue sports, not field hockey.Step 5: Three names are linked with field hockey, while one is associated with an entirely different sport. Verification / Alternative check: If you group the names by sport, you will place Dhanraj Pillay, Dhyan Chand, and Sardara Singh together under hockey. Pankaj Advani will naturally fall into a separate group of cue sports athletes. This separation confirms that Pankaj Advani is the odd one out. Why Other Options Are Wrong: Dhanraj Pillay: International Indian hockey player, so fits with Dhyan Chand and Sardara Singh.Dhyan Chand: Legendary Indian hockey player, part of the hockey group.Sardara Singh: Another famous Indian hockey player. Common Pitfalls: A common mistake is to focus on era or popularity instead of the sport itself. Even if players are from different generations, what matters here is that three names belong to the same game and one does not. Final Answer: The odd name is Pankaj Advani because he is associated with billiards and snooker, while the other three are hockey players.

Question 17

In this alphabet pattern question, find the odd group of letters from the given alternatives based on the constant step between consecutive letters.

Accepted Answer

Introduction / Context: This non verbal reasoning question involves groups of three letters. The aim is to identify which group of letters does not follow the same alphabetic stepping pattern as the others. These types of problems train your ability to recognize consistent increases or decreases in letter positions, which is a vital part of coding decoding and series questions. Given Data / Assumptions: - The letter groups are LJH, XUS, VTR, and FDB.- All letters belong to the English alphabet.- The order and spacing of letters in each group is the key to the pattern. Concept / Approach: A systematic way to attack these questions is to convert each letter into its numeric position and then find the difference between consecutive letters in the group. If three groups show the same constant step size and one group does not, that group is the odd one out. Here, we will examine whether the letters are moving backward in the alphabet by a fixed number of positions. Step-by-Step Solution: Step 1: In LJH, the letters are L, J, H. Their positions are 12, 10, and 8. Differences are minus 2 and minus 2.Step 2: In VTR, positions are V = 22, T = 20, R = 18. Differences are minus 2 and minus 2 again.Step 3: In FDB, positions are F = 6, D = 4, B = 2. Differences are minus 2 and minus 2.Step 4: In XUS, positions are X = 24, U = 21, S = 19. Differences are minus 3 and minus 2, so the steps are not equal.Step 5: Therefore, three groups show a constant backward step of minus 2 between letters, while XUS has an uneven pattern. Verification / Alternative check: You can also recite the letters. LJH goes backward skipping one letter each time, as does VTR and FDB. However, XUS does not follow a simple skip one backward pattern, which confirms that it is different from the rest. Why Other Options Are Wrong: LJH: Forms a regular backward sequence with a minus 2 step.VTR: Follows the same minus 2 backward pattern.FDB: Also a backward sequence with constant minus 2 steps. Common Pitfalls: Some candidates only check whether letters are decreasing and ignore whether the gap is constant. However, the key is that the size of the step must match across the groups, not just the general direction. Final Answer: The odd letter group is XUS because it does not follow the constant minus 2 backward step pattern that the other groups follow.

Question 18

In this number classification question based on divisibility by 9, select the odd number from the given alternatives.

Accepted Answer

Introduction / Context: This quantitative aptitude question checks your understanding of the divisibility rule for 9. Each option is a three digit number, and you have to select the one that does not share the same divisibility property as the others. Using digit sum rules is a fast and effective strategy for solving such questions, which often appear in competitive exams to test number sense. Given Data / Assumptions: - The numbers are 153, 261, 104, and 108.- All are positive integers with three digits.- We will apply the divisibility rule for 9. Concept / Approach: The divisibility rule for 9 states that a number is divisible by 9 if the sum of its digits is a multiple of 9. This rule is simple to apply, especially for medium sized numbers, and it avoids long division. If three numbers satisfy this rule and one does not, then that one is the odd number. Let us apply the rule systematically. Step-by-Step Solution: Step 1: For 153, the digit sum is 1 + 5 + 3 = 9, which is a multiple of 9. So 153 is divisible by 9.Step 2: For 261, the digit sum is 2 + 6 + 1 = 9, again a multiple of 9. So 261 is divisible by 9.Step 3: For 108, the digit sum is 1 + 0 + 8 = 9, also a multiple of 9. So 108 is divisible by 9.Step 4: For 104, the digit sum is 1 + 0 + 4 = 5, which is not a multiple of 9. Therefore, 104 is not divisible by 9.Step 5: Thus, three numbers are multiples of 9 and one is not. Verification / Alternative check: You may also check by direct division. 153 divided by 9 equals 17, 261 divided by 9 equals 29, and 108 divided by 9 equals 12. All results are whole numbers. However, 104 divided by 9 gives a non integer result, confirming that 104 is not a multiple of 9. Why Other Options Are Wrong: 153: Clearly divisible by 9 and fits the group.261: Also a multiple of 9 and belongs with 153 and 108.108: Again, divisible by 9 and not the odd one. Common Pitfalls: Students sometimes mix the rules for 3 and 9. Remember that the digit sum must be a multiple of 9, not just of 3, to guarantee divisibility by 9. Final Answer: The odd number is 104 because it is not divisible by 9, whereas 153, 261, and 108 are all multiples of 9.

Question 19

In this number pattern classification question, select the odd number from the given alternatives based on divisibility by 9.

Accepted Answer

Introduction / Context: This reasoning question involves medium sized numbers and tests your ability to detect a hidden divisibility pattern. All four numbers are divisible by 3, but a closer look shows that only one of them is also divisible by 9 in a particular way. You must identify which number behaves differently from the others based on this divisibility pattern. Given Data / Assumptions: - The numbers are 243, 687, 978, and 456.- All are positive three digit integers.- We use digit sum rules to test divisibility by 9. Concept / Approach: The divisibility rule for 9 says that a number is divisible by 9 if the sum of its digits is a multiple of 9. Another observation here is that 243 is a power of 3 (3^5), which makes it more strongly tied to the number 9 than the others. The main approach is to first test divisibility by 9 for each number and see which one stands out compared to the rest. Step-by-Step Solution: Step 1: For 243, the digit sum is 2 + 4 + 3 = 9. Since 9 is a multiple of 9, 243 is divisible by 9. In fact, 243 is equal to 3^5.Step 2: For 687, the digit sum is 6 + 8 + 7 = 21. Twenty one is not a multiple of 9, so 687 is not divisible exactly by 9.Step 3: For 978, the digit sum is 9 + 7 + 8 = 24, which is not a multiple of 9, so 978 is not divisible by 9.Step 4: For 456, the digit sum is 4 + 5 + 6 = 15. Fifteen is not a multiple of 9, so 456 is not divisible by 9.Step 5: Thus, only 243 is divisible by 9, and it is also a perfect power of 3, while the others are not. Verification / Alternative check: A quick calculation confirms that 243 divided by 9 equals 27, which is an integer. Dividing 687, 978, or 456 by 9 does not give a whole number. This confirms that 243 has a stronger connection to 9 and is different from the rest. Why Other Options Are Wrong: 687: Not divisible by 9, so it behaves like 978 and 456.978: Also not divisible by 9.456: Again, not divisible by 9 and therefore similar to 687 and 978. Common Pitfalls: Learners may notice that all numbers are divisible by 3 and think there is no difference. The correct approach is to look at divisibility by 9, which separates 243 from the rest. Always consider a stronger test if a weaker test does not distinguish the options. Final Answer: The odd number is 243 because it is divisible by 9 and is a perfect power of 3, whereas the other numbers are not divisible by 9.

Question 20

In this physics based reasoning question on physical quantities and units, select the odd word pair from the given alternatives.

Accepted Answer

Introduction / Context: This question belongs to the physical quantities and units category in general science reasoning. Each option is a pair of words that relates a quantity to a unit. Your job is to find the pair that does not follow the same relationship pattern as the others. Understanding which term is the physical quantity and which term is the unit is crucial in school level physics and in many aptitude examinations. Given Data / Assumptions: - The pairs are Length – Metre, Temperature – Degree, Ampere – Current, and Work – Joule.- We assume standard physics usage where a quantity has a specific unit.- The order of words in each pair is important for identifying the pattern. Concept / Approach: Generally, such questions present pairs where the first word is a physical quantity and the second word is its unit. To find the odd pair, we check whether this structure holds. If three pairs follow the pattern quantity – unit and one pair is reversed as unit – quantity, the reversed pair will be the odd one out. We will analyse each pair using this idea. Step-by-Step Solution: Step 1: Length – Metre. Length is a physical quantity. Metre is the standard unit of length. So this pair is quantity – unit.Step 2: Temperature – Degree. Temperature is a physical quantity and degree is used as a unit scale such as degree Celsius or degree Fahrenheit. So this pair also follows quantity – unit.Step 3: Work – Joule. Work is a physical quantity in mechanics, and joule is its SI unit. So this pair again is quantity – unit.Step 4: Ampere – Current. Current is the physical quantity and ampere is the SI unit of electric current. Here, the order is reversed and the unit comes first, followed by the quantity.Step 5: Hence, three pairs are in the format physical quantity – unit, and one pair is in the format unit – quantity. Verification / Alternative check: You can list the physical quantities separately: length, temperature, and work form one group, while current is the quantity hidden inside the pair ampere – current. For units, metre, degree, joule, and ampere form another group. Only in the third pair is the unit written first. Why Other Options Are Wrong: Length – Metre: Correctly ordered as quantity followed by unit.Temperature – Degree: Again correctly ordered as quantity followed by unit.Work – Joule: Also a proper quantity – unit relationship. Common Pitfalls: Some candidates simply look for less familiar words or for the only electrical term and pick it without checking the order. The real logic depends on whether the first term is the quantity and the second term is the unit. Final Answer: The odd pair is Ampere – Current because it is written in the order unit – quantity, whereas the other pairs are written as quantity – unit.
