Question 1

Classification – Ordered pairs (constant fraction rule): in three pairs the mapping is y = (3/4) * x exactly; one pair follows a different ratio. Identify the odd one out.  Options: 96 : 80, 64 : 48, 80 : 60, 104 : 78.

Accepted Answer

Introduction / Context:Ratio-based pair classification checks whether a consistent multiplicative factor maps x to y. Any deviation indicates the outlier.Given Data / Assumptions:Test y = (3/4) * x for each pair.(64,48): 64*(3/4)=48 ✔(80,60): 80*(3/4)=60 ✔(104,78): 104*(3/4)=78 ✔(96,80): 96*(3/4)=72 ≠ 80 ✖Concept / Approach:Use an exact fractional check (no rounding). The three compliant pairs share the same fraction 3/4; the remaining pair does not.Step-by-Step Solution:Compute (3/4)*x for each pair and compare to y.Mark the mismatch as the odd one out.Verification / Alternative check:Reduce y:x to lowest terms: 48:64=3:4, 60:80=3:4, 78:104=3:4, while 80:96=5:6.Why Other Options Are Wrong:64:48, 80:60, 104:78: All obey the same 3/4 ratio.Common Pitfalls:Accepting near-equality; proportional rules require exact equality in these puzzles.Final Answer:96 : 80

Question 2

Classification – Number pairs (square-difference test): in three pairs the difference (first − second) is a perfect square; one pair has a non-square difference. Find the odd one out.  Options: 61 - 12, 34 - 30, 44 - 31, 25 - 21.

Accepted Answer

Introduction / Context:Pair-difference classification often checks whether differences land on special sets (e.g., perfect squares). A single miss identifies the outlier.Given Data / Assumptions:61 − 12 = 49 = 7^2 → square.34 − 30 = 4 = 2^2 → square.25 − 21 = 4 = 2^2 → square.44 − 31 = 13 → not a perfect square.Concept / Approach:Compute the difference of each pair and test for perfect-square status.Step-by-Step Solution:Calculate each difference.Mark square vs non-square results.Identify the pair whose difference is not square.Verification / Alternative check:Nearest squares around 13 are 9 and 16; 13 is not square, confirming the exception.Why Other Options Are Wrong:61−12, 34−30, 25−21: Each yields a perfect square difference and thus belongs together.Common Pitfalls:Miscomputing 61−12 as 51; the correct result is 49.Final Answer:44 - 31

Question 3

Classification – Letter sequences (final step direction): in three sequences all steps move backward through the alphabet; in one sequence the last step reverses direction forward. Find the odd one out.  Options: T P L I, R N J F, S O K L, Y U Q M.

Accepted Answer

Introduction / Context:Multi-letter sequences often use constant backward jumps. Anomalies typically flip direction or alter the step size at the end.Given Data / Assumptions:T→P (−4), P→L (−4), L→I (−3) → all backward.R→N (−4), N→J (−4), J→F (−4) → all backward.Y→U (−4), U→Q (−4), Q→M (−4) → all backward.S→O (−4), O→K (−4), K→L (+1) → final step forward.Concept / Approach:Check the direction of each step. Three sequences maintain backward movement throughout; one reverses to a forward step at the end.Step-by-Step Solution:Compute successive differences for each sequence.Flag the single case with a positive final step.Verification / Alternative check:Even if some sequences change the magnitude (−3 vs −4), only one changes the sign from negative to positive at the end.Why Other Options Are Wrong:T P L I, R N J F, Y U Q M: Each maintains backward-only movement across all steps.Common Pitfalls:Counting inclusively or misreading letter positions near the ends of the alphabet.Final Answer:S O K L

Question 4

Classification – Unscramble each group to a meaningful English word, then find the odd one out based on semantic category (numbers vs operation).  Scrambles: GHIET, VEENS, VIDEID, ORFU.

Accepted Answer

Introduction / Context:Some verbal items combine anagramming with categorization. After unscrambling, three words belong to a single semantic class, and one falls outside it.Given Data / Assumptions:GHIET → EIGHT (number).VEENS → SEVEN (number).ORFU → FOUR (number).VIDEID → DIVIDE (arithmetic operation, not a number name).Concept / Approach:First, correctly unscramble each option. Then, group by semantic category: number names versus arithmetic operations.Step-by-Step Solution:Unscramble all four.Classify EIGHT/SEVEN/FOUR as number names.Classify DIVIDE as an operation.Select the operation as the odd one.Verification / Alternative check:Confirm each anagram via common word lists; only DIVIDE is not a cardinal number word.Why Other Options Are Wrong:GHIET/VEENS/ORFU: Each unscrambles to a cardinal number term and thus forms the majority class.Common Pitfalls:Mis-anagramming “VIDEID” as “DEVISED”; the exact letters yield DIVIDE.Final Answer:VIDEID

Question 5

Classification – Pairs of numbers (perfect squares): three pairs are both perfect squares; one pair contains non-square numbers. Identify the odd one out.  Options: 8 - 15, 25 - 36, 49 - 64, 81 - 100.

Accepted Answer

Introduction / Context:Square-number recognition is a common classification basis. When pairs are given, the test may require both members to be perfect squares.Given Data / Assumptions:25 and 36 are 5^2 and 6^2.49 and 64 are 7^2 and 8^2.81 and 100 are 9^2 and 10^2.8 and 15 are not perfect squares.Concept / Approach:Check square status of each number in every pair. The pair that fails the “both squares” rule is the outlier.Step-by-Step Solution:Verify 25–36 → both squares.Verify 49–64 → both squares.Verify 81–100 → both squares.Check 8–15 → neither is a square.Verification / Alternative check:Locate each value between consecutive squares: 8 is between 2^2 and 3^2; 15 is between 3^2 and 4^2.Why Other Options Are Wrong:25–36, 49–64, 81–100: Each pair consists entirely of perfect squares.Common Pitfalls:Confusing 16 (a square) with 15; careful reading avoids this slip.Final Answer:8 - 15

Question 6

Classification – Four-digit numbers (first equals last): in three numbers the first and last digits are equal; one number breaks this symmetry. Find the odd one out.  Options: 3463, 5725, 6514, 8948.

Accepted Answer

Introduction / Context:Digit-pattern classifications frequently check positional symmetry. A simple equality between first and last digits can define the majority pattern.Given Data / Assumptions:3463 → first digit 3, last digit 3 → equal.5725 → 5 and 5 → equal.8948 → 8 and 8 → equal.6514 → 6 and 4 → not equal.Concept / Approach:Test first–last digit equality for each number and select the one that fails.Step-by-Step Solution:Mark 3463, 5725, 8948 as symmetric at ends.Mark 6514 as asymmetric at ends.Therefore, 6514 is the odd one out.Verification / Alternative check:Read digits carefully; the center digits are irrelevant in this rule.Why Other Options Are Wrong:3463/5725/8948: Each satisfies the first=last rule.Common Pitfalls:Accidentally checking first=second or other non-specified comparisons; the rule concerns the extreme positions only.Final Answer:6514

Question 7

Classification – Political designations: three are executive/government office titles; one is a designation for a member of a legislature. Identify the odd one out.  Options: M.L.A., Prime Minister, President, Minister.

Accepted Answer

Introduction / Context:Civics classifications often separate executive offices from legislative roles. Identifying which label refers to a legislator distinguishes the outlier.Given Data / Assumptions:M.L.A. → Member of Legislative Assembly (legislator).Prime Minister → head of government (executive).President → head of state (executive/constitutional office).Minister → member of the executive (cabinet/portfolio holder).Concept / Approach:Group by branch: legislative role versus executive offices.Step-by-Step Solution:Tag Prime Minister/President/Minister as executive titles.Tag M.L.A. as a legislator.Hence, M.L.A. is the odd one out.Verification / Alternative check:Basic government-structure references confirm the separation of powers/roles.Why Other Options Are Wrong:Prime Minister/President/Minister: All are executive branch positions.Common Pitfalls:Assuming “Minister” could be religious; in this civic context it denotes a governmental executive office.Final Answer:M.L.A.

Question 8

Classification – Perfect squares: three numbers are exact squares; one is not a perfect square. Which is the odd one out?  Options: 49, 36, 65, 100.

Accepted Answer

Introduction / Context:Square recognition is foundational in numerical classification. A single non-square among well-known squares is the intended outlier.Given Data / Assumptions:49 = 7^2.36 = 6^2.100 = 10^2.65 is between 8^2=64 and 9^2=81 → not a square.Concept / Approach:Check each value against nearby integer squares or factorization to confirm square status.Step-by-Step Solution:Verify 49, 36, 100 as squares.Recognize 65 is not an exact square.Verification / Alternative check:Prime factorization: 65 = 5 * 13 contains no repeated prime factors, hence not a square.Why Other Options Are Wrong:49/36/100: Each is a perfect square and forms the majority class.Common Pitfalls:Confusing 64 (square) with 65 due to adjacency.Final Answer:65

Question 9

Classification – Animal classes/habitats: three are mammals; one is an insect. Identify the odd one out.  Options: Langur, Whale, Scarab, Donkey.

Accepted Answer

Introduction / Context:Biological classification can separate options by class. Mammals share key traits distinct from insects, making the outlier easy to spot.Given Data / Assumptions:Langur: primate (mammal).Whale: marine mammal.Donkey: equid (mammal).Scarab: beetle (insect).Concept / Approach:Group by biological class: Mammalia versus Insecta.Step-by-Step Solution:Identify Langur/Whale/Donkey as mammals.Identify Scarab as an insect.Therefore, Scarab is the odd one out.Verification / Alternative check:Taxonomic references confirm whales, langurs, and donkeys are mammals; scarabs are coleopteran insects.Why Other Options Are Wrong:Langur/Whale/Donkey: All belong to class Mammalia.Common Pitfalls:Assuming “whale” is a fish due to habitat; it is a mammal.Final Answer:Scarab

Question 10

Classification – Perfect squares vs non-square: three numbers are perfect squares; one is not. Which is the odd one out?  Options: 210, 529, 289, 196.

Accepted Answer

Introduction / Context:One common numeric contrast is square versus non-square. Recognizing classic square values isolates the outlier quickly.Given Data / Assumptions:529 = 23^2.289 = 17^2.196 = 14^2.210 is not a perfect square; it lies between 14^2=196 and 15^2=225.Concept / Approach:Confirm square status via known squares or factorization.Step-by-Step Solution:Mark 529, 289, 196 as squares.Mark 210 as non-square.Select 210 as the odd one out.Verification / Alternative check:Prime factorization of 210 = 2 * 3 * 5 * 7 includes no repeated prime factors, so it cannot be a square.Why Other Options Are Wrong:529/289/196: Each is exactly n^2 for integer n.Common Pitfalls:Mistaking 225 (15^2) for 210; the latter is not square.Final Answer:210

Question 11

Four of the following five words are alike in a certain way and form a group. Tooth, Chin, Nose, Ear and Eye are given. In this classification question, which one does not belong to that group?

Accepted Answer

Introduction / Context:This is a classic classification or odd one out question. You are given five body parts: tooth, chin, nose, ear and eye. Four of them are similar to each other in a particular way, and one is different. Your task is to identify the item that does not fit into the same category as the other four. Such questions check your ability to see patterns and group related items based on common characteristics. Given Data / Assumptions:• The given options are Tooth, Chin, Nose, Ear and Eye.• Only one of these should be selected as the odd one out.• We look for a natural, logical grouping based on anatomy.• All terms are common English names for parts of the human body. Concept / Approach:A simple way to tackle such problems is to check what each item is a part of and how it is located on the body. The chin, nose, ear and eye are all external features located on the face. They are clearly visible facial features. A tooth, however, is located inside the mouth. While it is part of the head, it is not considered a direct external facial feature like the others. Therefore the natural grouping is facial features (chin, nose, ear, eye), and tooth is the odd one out. Step-by-Step Solution:Step 1: List each item with its primary body location.Step 2: Chin: this is the lower part of the face below the mouth.Step 3: Nose: a prominent feature on the middle of the face used for breathing and smell.Step 4: Ear: an organ on the side of the head, externally visible, used for hearing and balance.Step 5: Eye: a visible organ on the face used for seeing.Step 6: Tooth: located inside the mouth, attached to the gums, not part of the outer facial surface.Step 7: Identify the common group as visible external facial features (chin, nose, ear, eye), leaving tooth as the odd one. Verification / Alternative check:You can also test other possible groupings, such as sensory organs. Nose, ear and eye are sense organs, but chin and tooth are not, so that pattern leaves two odd ones instead of one. Another attempt might use hardness (tooth is hard tissue), but chin is also bone covered with skin, so this is less clear. The most straightforward and unique pattern is that four are obvious face parts seen from the outside, while tooth is internal to the mouth. That gives a single odd element, tooth, which is what we need. Why Other Options Are Wrong:Chin: It is clearly an external facial feature, similar to nose, ear and eye.Nose: It is a prominent part of the face, visible externally.Ear: Another external part of the face/head, visible on the outside.Eye: Again, a visible part of the face. Common Pitfalls:Some students may initially think of sensory organs and discard chin instead, but then are left with tooth also not fitting the sensory organ pattern. When checking for odd one out, the correct pattern should group four items cleanly and leave only one item out. Here, the external face feature classification works perfectly if we choose tooth as the odd one. That is why tooth is the correct answer. Final Answer:The word that does not belong to the group is Tooth.

Question 12

In this classification (odd one out) question, the words crusade, campaign, expedition and cruise are given. All but one are similar in meaning or usage. Which word does not belong to this group?

Accepted Answer

Introduction / Context:This is a vocabulary-based classification question. You are given four main options: crusade, campaign, expedition and cruise (plus one extra synonym-like distractor), and asked to choose the odd one out. To solve this, you need to consider the meanings, typical usage and tone of each word and see which one does not fit with the others as a mission or serious undertaking. Given Data / Assumptions:• The main words to compare are crusade, campaign, expedition and cruise.• All are English nouns that can describe activities or journeys.• The question wants one word that does not match the sense or seriousness of the others.• We assume standard modern English meanings. Concept / Approach:Crusade, campaign and expedition typically imply purposeful, often serious missions. A crusade can be a long and passionate movement for a cause. A campaign can be a planned series of actions, often for political, social or military objectives. An expedition is a planned journey, often for exploration, research or war. By contrast, a cruise is generally a leisurely pleasure trip by ship, associated with relaxation and tourism rather than a serious mission. Therefore, cruise is the odd one out because it lacks the sense of serious, goal-oriented undertaking that the other words share. Step-by-Step Solution:Step 1: Consider crusade. It suggests a serious, long-term effort or movement for some cause, sometimes religious or moral in nature.Step 2: Consider campaign. This word often refers to a coordinated set of activities toward a specific goal, such as an election campaign or a marketing campaign.Step 3: Consider expedition. It means a planned journey, typically organised for exploration, research or sometimes a military objective. It is purposeful and structured.Step 4: Consider cruise. This primarily means a journey by ship or boat taken for pleasure, relaxation or tourism, often without any deeper mission beyond recreation.Step 5: Group the words: crusade, campaign and expedition all share a sense of serious purpose and mission; cruise is mainly leisure travel.Step 6: Therefore cruise does not belong with the other three. Verification / Alternative check:Try grouping the words by whether they can naturally take a target or cause. You can say a crusade against corruption, a campaign for better health, or an expedition to the Arctic, each with a clear objective. Saying a cruise against corruption or a cruise for better health sounds odd; cruise does not normally take a serious target. Another test is emotional tone: crusade, campaign and expedition often involve effort and risk, while cruise implies comfort and enjoyment. This confirms cruise as the odd one out. Why Other Options Are Wrong:Crusade: Fits with campaign and expedition as a purposeful mission or movement.Campaign: Also fits as a planned series of activities towards a goal.Expedition: A carefully organised journey, very much in line with the mission-like flavour of crusade and campaign.Operation (if considered): Again, can indicate a planned action or series of actions; still closer to the mission theme than cruise. Common Pitfalls:Some learners focus only on the fact that all four words can involve travel and therefore hesitate. The trick is to examine typical usage: three words are strongly associated with organised, goal-oriented actions, while cruise is predominantly associated with relaxed pleasure travel. That subtle but important difference in purpose and tone identifies cruise as the odd one out. Final Answer:The odd word in the group is cruise.

Question 13

In the following question, four letter groups are given: DEB, RTP, HIF and NOL. Three of these follow a similar alphabetical pattern, and one is different. Which letter group is different from the other three responses?

Accepted Answer

Introduction / Context:This is a letter classification question involving patterns based on alphabetical positions. You are given four three-letter combinations: DEB, RTP, HIF and NOL. Three follow the same positional pattern in the alphabet, but one breaks the rule. Such questions test your ability to convert letters into numerical positions (A = 1, B = 2, ..., Z = 26) and observe consistent differences between the letters in each group. Given Data / Assumptions:• The letter groups given are: DEB, RTP, HIF and NOL.• We use standard English alphabetical positions.• We are looking for a consistent pattern in three groups and one group that does not obey that pattern. Concept / Approach:A systematic approach is to translate each letter into its alphabetical position and then examine the differences between the first, second and third letters. For three of the groups, the pattern is that the second letter is one position after the first, and the third letter is three positions before the second. In notation, second = first + 1 and third = second − 3. The group that does not follow this pattern will be the odd one out. Step-by-Step Solution:Step 1: Convert DEB into positions: D = 4, E = 5, B = 2.Step 2: Check the differences: from D to E is +1 (4 to 5), from E to B is −3 (5 to 2). So DEB follows the +1, −3 pattern.Step 3: Convert HIF: H = 8, I = 9, F = 6.Step 4: Differences: from H to I is +1 (8 to 9), from I to F is −3 (9 to 6). So HIF also follows +1, −3.Step 5: Convert NOL: N = 14, O = 15, L = 12.Step 6: Differences: from N to O is +1 (14 to 15), from O to L is −3 (15 to 12). So NOL again follows +1, −3.Step 7: Convert RTP: R = 18, T = 20, P = 16.Step 8: Differences: from R to T is +2 (18 to 20), from T to P is −4 (20 to 16). This is not +1, −3 like the others.Step 9: Therefore, RTP does not follow the same pattern and is the odd one out. Verification / Alternative check:Re-check the pattern across the three consistent groups: DEB, HIF and NOL. In each, letters are close in the alphabet with a gentle rise then a small drop. RTP, however, jumps further, skipping one additional letter in both steps. If we tried to impose a different pattern, it would group only two items at a time; the only pattern that neatly groups three items is the +1, −3 rule, leaving RTP as the unique exception. Why Other Options Are Wrong:DEB: Fits the pattern with +1 then −3 differences.HIF: Also fits the same sequence of differences.NOL: Again follows +1 then −3, matching DEB and HIF.None of these: Incorrect because we have clearly found one group, RTP, that does not match the others. Common Pitfalls:A common error is to look only at visual similarity or at the first letters and ignore the precise numeric differences. Another mistake is to stop after testing just one or two groups and miss the consistent pattern among three of them. Always check each group carefully and write out the position numbers to reveal hidden arithmetic patterns. Here, this simple discipline reveals that RTP is the only group with +2 and −4 rather than +1 and −3, so it must be the odd one out. Final Answer:The letter group that is different from the other three is RTP.

Question 14

In this classification question, each option shows a pair of related words: Flower : Petal, Circle : Arc, Cover : Page, Chair : Leg. Three of the pairs show the same kind of relationship between whole and part. Which pair is different from the other…

Accepted Answer

Introduction / Context:This is an analogy-based classification question. Each option gives a pair of related words. Your task is to identify which pair does not share the same type of relationship as the others. These items test whether you can see that three pairs present a clear whole–part relationship, while one pair is different because both words in that pair represent parts of another whole rather than a whole and its part. Given Data / Assumptions:• The given pairs are: Flower : Petal, Circle : Arc, Cover : Page, Chair : Leg (and an extra illustrative pair Book : Chapter).• Three pairs must show a consistent relation.• One pair must break that pattern.• We use standard meanings of the words in English. Concept / Approach:Look at each pair in terms of whole versus part. A petal is part of a flower. An arc is part of a circle. A leg is part of a chair. In each of these, the first term is the whole object and the second term is a physical portion of that whole. But in the pair Cover : Page, neither word is the whole object. Both cover and page are parts of a larger whole, namely a book or a notebook. Therefore, this pair does not follow the same whole–part pattern and must be the odd one out. Step-by-Step Solution:Step 1: Analyse Flower : Petal. A petal is one of the units that form a flower; it is clearly a part of the whole flower.Step 2: Analyse Circle : Arc. An arc is a segment or a portion of a circle; again, it is a part of the whole geometric figure.Step 3: Analyse Chair : Leg. A leg is one of the parts that supports a chair; a typical chair has multiple legs, each being part of the whole structure.Step 4: In all three, the pattern is Whole : Part.Step 5: Now analyse Cover : Page. A cover is part of a book (or notebook), and a page is also part of a book.Step 6: Here, both words represent parts of some third object (a book); neither is a whole that contains the other as a part.Step 7: Therefore Cover : Page does not share the same whole–part pattern as the other three pairs. Verification / Alternative check:Another way to check is to ask: can the second item exist as a natural component of the first? A petal is literally part of a flower, an arc is an identified piece of a circle, and a leg is a structural component of a chair. However, a page is not a component of a cover; both are placed together in a book, but one is not part of the other. This contrast confirms that Cover : Page is different from the rest. Why Other Options Are Wrong:Flower : Petal: Correctly shows a whole–part relation.Circle : Arc: Again, a clear whole–part relationship.Chair : Leg: The leg is a part of the chair structure.Book : Chapter (if considered): The chapter is part of the book, aligning with the whole–part pattern. Common Pitfalls:Some candidates get distracted by the idea that cover and page belong to the same domain (both parts of a book) and mistakenly treat them as having a meaningful relationship. While they are associated, the relationship is not the same whole–part type that appears in the other pairs. To find the odd one out, always look for which pair breaks the shared underlying relation, not just which words seem less related at first glance. Final Answer:The pair that is different from the others is Cover : Page.

Question 15

In this number classification question, the pairs 7 : 22, 12 : 37, 8 : 33 and 15 : 46 are given. Three of these pairs follow a similar numerical pattern. Which number pair is different from the others?

Accepted Answer

Introduction / Context:This is a number pair classification problem, where each option consists of two numbers related by a certain arithmetic rule. You are given the pairs 7 : 22, 12 : 37, 8 : 33 and 15 : 46. Three of these follow an identical arithmetic pattern, while one does not. The goal is to find the odd pair by identifying the underlying rule that connects the numbers in the majority of the pairs. Given Data / Assumptions:• The number pairs are: (7, 22), (12, 37), (8, 33) and (15, 46).• We suspect a linear relation of the form second = 3 * first + constant.• The correct pattern should apply to three pairs and fail for exactly one pair. Concept / Approach:Check whether multiplying the first number by 3 and then adding a constant yields the second number. For 7 : 22, 3 * 7 + 1 = 21 + 1 = 22. For 12 : 37, 3 * 12 + 1 = 36 + 1 = 37. For 15 : 46, 3 * 15 + 1 = 45 + 1 = 46. So in three pairs the second number equals 3 times the first number plus 1. Now test this rule on 8 : 33. We get 3 * 8 + 1 = 25, which is not 33. Hence 8 : 33 does not conform to the same pattern and is the odd one out. Step-by-Step Solution:Step 1: For the pair 7 : 22, compute 3 * 7 + 1 = 21 + 1 = 22. The rule second = 3 * first + 1 works here.Step 2: For 12 : 37, compute 3 * 12 + 1 = 36 + 1 = 37. Again, the rule holds.Step 3: For 15 : 46, compute 3 * 15 + 1 = 45 + 1 = 46. The rule still holds.Step 4: For 8 : 33, compute 3 * 8 + 1 = 24 + 1 = 25, which does not equal 33.Step 5: Therefore, 8 : 33 fails to follow the pattern that works for the other three pairs.Step 6: Hence 8 : 33 is the different, or odd, number pair. Verification / Alternative check:If we look for other patterns, such as adding a fixed number or squaring, we do not find a simple rule that fits as neatly as second = 3 * first + 1 for three of the pairs. Only 7 : 22, 12 : 37 and 15 : 46 can be described with the same linear formula. The pair 8 : 33 fits neither this rule nor any obvious variant that only excludes one pair. Thus selecting 8 : 33 as the odd one is the most consistent choice. Why Other Options Are Wrong:7 : 22: Follows the second = 3 * first + 1 rule.12 : 37: Also fits the same pattern.15 : 46: Again matches the rule exactly.None of these: Incorrect because we clearly have three pairs that follow a pattern and one that does not. Common Pitfalls:Without testing each pair, some students guess randomly, or they try a more complicated formula and get lost. The key strategy is to look for a simple arithmetic relation like multiplication plus a constant and then verify it systematically across all options. Doing so reveals that 8 : 33 is the only pair that does not satisfy the simple linear rule satisfied by the others. Final Answer:The number pair that is different from the others is 8 : 33.

Question 16

In this odd one out question, you are given four animals: Lion, Bear, Cheetah and Leopard. Three of these belong to the same general group of big cats. Which animal does not belong to that group?

Accepted Answer

Introduction / Context:This classification question uses animal names to test whether you can recognise similarities and differences in biological grouping. You are given four animals: lion, bear, cheetah and leopard. Three of them are large wild cats (big cats), while one belongs to a different family altogether. The task is to identify which animal is different from the others in terms of its zoological group. Given Data / Assumptions:• The animals listed are Lion, Bear, Cheetah and Leopard.• We consider standard biological classification at a general level, not very technical taxonomy.• Three animals are big cats; one is not a cat at all. Concept / Approach:Lion, cheetah and leopard are all large felines. They belong to the family Felidae and are commonly known as big cats. They share cat-like features such as retractable claws (with minor exceptions), feline body shape, and predatory behaviour typical of cats. Bear, however, is not a cat; it belongs to the family Ursidae. Bears have a different body structure, different type of claws, and a different evolutionary line. Therefore, bear clearly stands out as the odd one that does not belong to the big cat group. Step-by-Step Solution:Step 1: Identify lion. It is a large wild cat, often called the king of the jungle, and is a member of the cat family.Step 2: Identify cheetah. It is also a large cat, famous for its speed and spotted coat, belonging to the cat family.Step 3: Identify leopard. Another big cat, known for its rosette-patterned spots and climbing ability, again in the cat family.Step 4: Identify bear. Bears are large mammals, but not cats; they form their own family and have very different body shapes and lifestyles.Step 5: Group the animals: lion, cheetah and leopard can be grouped under big cats, whereas bear cannot.Step 6: Therefore, bear is the odd one out. Verification / Alternative check:Consider other features like body structure and predatory style. Lions, cheetahs and leopards all have feline features such as flexible bodies, long tails for balance and hunting techniques typical of cats. Bears, on the other hand, have heavier, more robust frames and a different gait. Also, if we added another option such as tiger, it would sit naturally with lion, cheetah and leopard, confirming that the big cat group is the intended pattern. Bear remains the only animal that clearly does not fit that group. Why Other Options Are Wrong:Lion: A classic big cat and fits well with cheetah and leopard.Cheetah: Another big cat, matching lion and leopard.Leopard: Again, a big cat with similar ecological and physical traits.Tiger (if considered): Also a big cat, so it would fit the group, not break it. Common Pitfalls:Because all four animals are large, wild mammals, some students might momentarily think they are equally similar. The key is to look at more specific grouping, like cat family versus non-cat. Once you classify lion, cheetah and leopard as big cats, it becomes obvious that bear, as a non-feline, is the odd one out. Final Answer:The animal that does not belong to the big cat group is the Bear.

Question 17

Three of the following four options are items that people wear, while one is a person who provides a service. Shirt, Shoe, Ring and Cobbler are given. Which one does not belong to that group?

Accepted Answer

Introduction / Context:This classification question contrasts objects with a person. The options given are shirt, shoe, ring and cobbler. Three of these are wearable items, while one is the name of a person who works with one of those items. The goal is to select the word that is different in type from the others. This tests your ability to see category differences between nouns referring to objects and nouns referring to people. Given Data / Assumptions:• The listed words are Shirt, Shoe, Ring and Cobbler.• Shirt, shoe and ring are all items that a person can wear.• Cobbler is a person who repairs or makes shoes.• We are asked to choose the one that does not fit with the others. Concept / Approach:The straightforward approach is to separate items that are wearable from roles or occupations. Shirt is an article of clothing worn on the upper body. Shoe is an item worn on the feet. Ring is a piece of jewellery worn on the finger. All three are physical objects that people put on. Cobbler, however, is not an object but a person—specifically, a craftsman who makes or repairs shoes. Thus, Cobbler is the odd one out because it represents an occupation rather than a wearable item. Step-by-Step Solution:Step 1: Examine Shirt. It is worn on the torso as an item of clothing.Step 2: Examine Shoe. It is worn on the feet as footwear.Step 3: Examine Ring. It is worn on a finger as jewellery.Step 4: Note that all three are concrete items that a person can put on and wear.Step 5: Examine Cobbler. A cobbler is a person who repairs or makes shoes.Step 6: Cobbler is not an item that can be worn; it is a profession or role.Step 7: Therefore Cobbler is different from the other three, which are wearable objects. Verification / Alternative check:Another way to verify is to think: If you go shopping for clothes and accessories, you might buy a shirt, a pair of shoes or a ring. You would not buy a cobbler in the same sense; instead, you might pay a cobbler for services. This clearly separates cobbler into the category of service provider, leaving the other three as products you wear. No other option fits the role-of-a-person category, so Cobbler is the unique odd one out. Why Other Options Are Wrong:Shirt: A wearable garment; naturally groups with shoe and ring.Shoe: Footwear, again a wearable item.Ring: A wearable piece of jewellery for fingers.Hat (if considered): Also a wearable item, not different in the same way as Cobbler. Common Pitfalls:Because cobbler is strongly associated with shoes, some students may initially see all four words as related to clothing or footwear and be unsure. The trick is to note the grammatical type: the first three are things you wear, while the last is a person who works with one of those things. Once you distinguish object from profession, Cobbler clearly emerges as the odd one out. Final Answer:The item that does not belong to the group is Cobbler.

Question 18

In this number classification question, the numbers 64, 162, 27 and 144 are given. Three of these numbers are perfect powers (either perfect squares or perfect cubes of integers). Which number is different from the others in this group?

Accepted Answer

Introduction / Context:This classification question involves recognising special properties of numbers, particularly perfect squares and perfect cubes. You are given the numbers 64, 162, 27 and 144. Three of them can be expressed as an exact integer power (square or cube) of a positive integer, while one cannot. The task is to determine which number does not fit the pattern of being a perfect square or cube. Given Data / Assumptions:• The numbers to compare are 64, 162, 27 and 144.• A perfect square is a number of the form n^2 for some integer n.• A perfect cube is a number of the form n^3 for some integer n.• We check which numbers can be written exactly as such powers. Concept / Approach:We test each number to see if it is a perfect square or a perfect cube. 64 is a well known perfect power: 64 = 4^3 and also 64 = 8^2. The number 27 is 3^3, a perfect cube. The number 144 is 12^2, a perfect square. Now we examine 162. It can be factorised as 2 * 81 = 2 * 3^4, but there is no integer n such that n^2 = 162 or n^3 = 162. That means 162 is not a perfect square or perfect cube, while the other three numbers are. Therefore, 162 is the odd one out. Step-by-Step Solution:Step 1: Test 64. We know 8 * 8 = 64, so 64 is 8^2, a perfect square. Also, 4 * 4 * 4 = 64, so 64 is also 4^3, a perfect cube. It is clearly a perfect power.Step 2: Test 27. We know 3 * 3 * 3 = 27, so 27 is 3^3, a perfect cube.Step 3: Test 144. We know 12 * 12 = 144, so 144 is 12^2, a perfect square.Step 4: Test 162. Factor 162: 162 = 2 * 81 = 2 * 3^4. The square root of 162 is not an integer (it lies between 12 and 13), and the cube root is also not an integer (it lies between 5 and 6).Step 5: Therefore 162 is not a perfect square or perfect cube.Step 6: Since three numbers (64, 27 and 144) are perfect powers, and 162 is not, 162 is the odd one out. Verification / Alternative check:We can further verify by checking nearby squares and cubes. For squares, 12^2 = 144 and 13^2 = 169, so 162 is in between and cannot be a perfect square. For cubes, 5^3 = 125 and 6^3 = 216, so 162 lies between them and cannot be a perfect cube. No other simple integer power equals 162. This confirms that 162 does not share the perfect square or cube property that the other three numbers have. Why Other Options Are Wrong:64: A perfect square (8^2) and also a perfect cube (4^3), so it definitely fits the pattern.27: A perfect cube (3^3), also fitting the pattern.144: A perfect square (12^2), again fitting the pattern.None of these: Incorrect, because we clearly identified 162 as not being a perfect square or cube. Common Pitfalls:Some students may be distracted by the fact that 162 is not as commonly memorised as a standard square or cube and might suspect another number instead. The safe method is to check each number carefully with nearby squares and cubes. Once you verify that 64, 27 and 144 are exact powers and 162 is not, the classification becomes clear: 162 is the odd one out. Final Answer:The number that is different from the others is 162.

Question 19

Among the given time-related words, choose the one which is least like the others in the group.

Accepted Answer

Introduction / Context:This logical reasoning question belongs to the \"classification\" or \"odd one out\" type. You are given several closely related words and asked to select the one which does not belong with the others in the same way. These questions test your ability to see subtle category differences and group concepts based on their underlying meaning rather than just their spelling or sound. Given Data / Assumptions:The words given are Day, Calendar, Date, Month and Year.All of these are connected to the idea of time.Day, Date, Month and Year are units or labels used to measure or mark time.A Calendar is a physical or conceptual tool used to organise, display and track these time units.We are looking for the single word whose nature or function is different from the remaining words. Concept / Approach:In classification problems, a good first step is to decide what category three or four of the items naturally form. Once that dominant category is clear, the remaining item which does not fit becomes the odd one out. Here, Day, Date, Month and Year are all specific measures or labels of time. A Day is a basic time unit of 24 hours. A Date is a specific labelled day in the calendar, such as 10 March. A Month is a larger time unit composed of many days. A Year is an even larger time unit made up of months. In contrast, a Calendar is not itself a time unit; it is an organisational system or device that arranges these units. Step-by-Step Solution:Step 1: List the items and ask what each one represents in relation to time: Day, Calendar, Date, Month, Year.Step 2: Recognise that Day, Date, Month and Year are measures of time or specific positions in the flow of time.Step 3: Understand that a Day is a 24 hour period, a Month is a group of days, and a Year is a group of months.Step 4: A Date is a labelled day within this system, for example, 15 August or 1 January.Step 5: A Calendar, on the other hand, is the system, chart or device that displays and arranges days, months and years. It is a time-organising tool, not a unit itself.Step 6: Therefore, four items are time units or time labels, and one item is the organiser of those units.Step 7: The single item whose role is different is Calendar. Verification / Alternative check:Imagine using each item in a sentence about duration. You can say, \"I will stay for three days\", \"She will arrive next month\", \"The event is on that date\", or \"It took a full year\". In each sentence, you are talking about a duration or a specific point in time. But you do not normally say, \"I will stay for one calendar\" to mean a period; instead, you say, \"I will mark it on the calendar\". This shows that Calendar is an object or system, while the others are measures or labels of time. Why Other Options Are Wrong:Day is a basic time unit and fits well with Month and Year. Date is a labelled day and is directly part of what a Calendar displays. Month and Year are standard higher-level units of time. Year, like Day and Month, is still a clear time unit, so it is not the odd one out. Only Calendar functions as a tool or system rather than as a time unit. Common Pitfalls:Some learners are distracted by the fact that all the words are linked to time and may mistakenly think that there is no odd one out at all. Others may focus on spelling or word length rather than meaning. In odd one out questions, always prioritise meaning and function over superficial features like number of letters. Group the majority by a clear concept first and then see which item does not fit that concept. Final Answer:The word which is least like the others is Calendar.

Question 20

Choose the pair of words which is related in a different way from the other three pairs.

Accepted Answer

Introduction / Context:This logical reasoning question asks you to pick the pair of words which is differently related from the others. All the options are verb pairs describing actions, often where one action is weaker or milder and the other is a stronger or more intense version. The task is to spot the one pair that does not follow the same intensity pattern. Given Data / Assumptions:Option A: Flurry : Blizzard.Option B: Moisten : Drench.Option C: Prick : Stab.Option D: Scrub : Polish.Option E: Drizzle : Downpour.In classification questions, three or four options will usually share the same type of relationship, while one option will differ in a clear logical way. Concept / Approach:The first three given pairs and the last added pair all strongly suggest a \"degree\" or \"intensity\" relationship. In each of those, the first word describes a mild, light or less intense version of an action or event, and the second word describes a much stronger, more intense or severe form of the same basic thing. The odd pair would be the one where the two words are related in some other way, for example, as two different actions rather than as mild and strong versions of the same action. Step-by-Step Solution:Step 1: Consider \"Flurry : Blizzard\". A flurry is a light or brief snowfall, while a blizzard is a very heavy, severe snowstorm. Thus, a blizzard can be seen as an intense form of a flurry.Step 2: Look at \"Moisten : Drench\". To moisten something is to make it slightly wet, while to drench something is to soak it completely. Again, the second word expresses a stronger degree of the same general action.Step 3: Examine \"Prick : Stab\". A prick is a very small, shallow piercing, while a stab is a deep or forceful thrust with something sharp. Stab is a much more severe version of the basic action described by prick.Step 4: Check \"Drizzle : Downpour\". A drizzle is very light rain, while a downpour is very heavy rain. The intensity clearly increases from the first word to the second.Step 5: Now analyse \"Scrub : Polish\". Scrub means to rub hard, usually with a brush or cloth, in order to remove dirt. Polish means to rub in order to make something smooth and shiny.Step 6: Scrubbing and polishing are both cleaning or surface treatments, but polishing is not simply a more intense version of scrubbing. They are related but different actions, often performed at different stages (scrub first to clean, polish later to shine).Step 7: Therefore, Scrub : Polish is the only pair which does not show a clear mild-to-intense relationship of the same phenomenon. It is differently related from the others. Verification / Alternative check:One way to verify is to rewrite the pairs as \"small X\" versus \"large X\". Flurry is a small snowstorm and blizzard is a large snowstorm. Moisten is to make a little wet and drench is to make very wet. Prick is a small wound, stab is a serious wound. Drizzle is light rain, downpour is heavy rain. For Scrub and Polish, you cannot naturally say that polish is just a stronger scrub; instead, it is a separate action used for a different purpose, which confirms that the pairing is of a different type. Why Other Options Are Wrong:All other options show a clear minor-major or light-heavy relationship within the same domain. In each case, the second word is essentially the same phenomenon but intensified. Because they follow the same pattern, they cannot be the odd pair. Only the pair Scrub : Polish represents two related but distinct processes rather than degrees of the same one. Common Pitfalls:Sometimes learners focus only on whether the words are connected at all and overlook the special type of connection. It is not enough that the two words be vaguely related; you must look for a consistent pattern across all the options. Paying attention to whether the second word could be described as a stronger form of the first is the key to this question. Final Answer:The pair which is differently related from the others is Scrub : Polish.
