Question 1

Choose the word that is least like the other words in the group from the following: Shoulder, Foot, Finger and Elbow. Three of these refer to parts of the arm or hand, while one is a part of the leg.

Accepted Answer

Introduction / Context: This is a simple classification question based on basic human anatomy. You are given four words that name different body parts: Shoulder, Foot, Finger and Elbow. Three of these are located on the upper limb (arm and hand region), while one is found on the lower limb (leg region). The question asks you to identify the body part that does not belong with the others and mark it as the odd word out. Given Data / Assumptions: Shoulder: joint connecting the upper arm to the torso. Foot: lower extremity attached to the leg. Finger: one of the digits of the hand. Elbow: joint between upper arm and forearm. We group parts according to whether they belong to the arm and hand or to the leg and foot region. Concept / Approach: The upper limb of the human body includes the shoulder, arm, elbow, forearm, wrist and hand (including fingers). The lower limb includes the thigh, knee, leg, ankle and foot. In the given list, Shoulder, Finger and Elbow are all located on the upper limb, whereas Foot is a part of the lower limb. In odd one out questions, the item belonging to a different category or region is considered the least like the others and should be selected as the answer. Step-by-Step Solution: Step 1: Consider Shoulder.The Shoulder is the joint that connects the upper arm to the trunk of the body. It clearly belongs to the upper limb region.Step 2: Consider Finger.A Finger is one of the digits of the hand, which is the terminal part of the upper limb. So Finger also belongs to the upper limb.Step 3: Consider Elbow.The Elbow is the joint between the upper arm and the forearm. It is part of the arm region and again clearly linked to the upper limb.Step 4: Consider Foot.The Foot is the lower extremity of the leg, used for standing and walking. It belongs to the lower limb, not the upper limb.Step 5: Identify the odd word.Three items (Shoulder, Finger and Elbow) belong to the arm and hand region, while Foot belongs to the leg region. Therefore Foot is the odd one out. Verification / Alternative check: A quick mental diagram of the human body helps confirm the answer. If you imagine the skeleton or a basic body outline, you can place the Shoulder at the top of the arm, the Elbow in the middle of the arm, and the Fingers at the end of the arm. The Foot, however, clearly appears at the end of the leg near the ground. Since the question groups words by their location on the body, it is very clear that Foot belongs to a different limb than the others. Why Other Options Are Wrong: Shoulder: Located at the upper limb attachment and grouped with Elbow and Finger. Finger: Part of the hand on the upper limb; it is consistent with the Shoulder and Elbow grouping. Elbow: A joint in the arm region, again belonging to the upper limb category. Common Pitfalls: Because all four options are body parts, some candidates may initially feel that none stands out. However, the usual trick in such questions is to separate items by region or function. Whenever you see a mix of body parts, ask yourself whether they all belong to the same limb or the same system (for example, digestive, respiratory, skeletal). This simple check quickly reveals that Foot is from the leg region, while the others are from the arm and hand region. Final Answer: The odd word is Foot, because Shoulder, Finger and Elbow are parts of the upper limb, whereas Foot is part of the lower limb.

Question 2

Choose the word that is least like the other words in the group from the following: Canoe, Dingy, Yatch and Igloo. Three of these are small watercraft used for travelling on water, while one is a type of shelter built on land.

Accepted Answer

Introduction / Context: This is a straightforward classification question involving common nouns. You are given four words: Canoe, Dingy, Yatch and Igloo. Three of these words name watercraft or boats used for travelling on lakes, rivers or seas, while one names a type of house or shelter made of compacted snow. You must identify the word that does not belong to the group of water vehicles and mark it as the odd one out. Given Data / Assumptions: Canoe: a small, narrow boat typically paddled with a paddle. Dingy (dinghy): a small boat, often used as a tender or for short trips. Yatch (yacht): a relatively large and often luxurious boat used for pleasure cruising or racing. Igloo: a dome shaped shelter built from blocks of snow, traditionally used in Arctic regions. We group words according to whether they refer to watercraft or to stationary shelters on land. Concept / Approach: The concept tested is categorisation by function and environment. Canoe, dinghy and yacht are all vehicles that float on water and are designed for transport or recreation on seas, rivers or lakes. Igloo, by contrast, is a shelter built on land, specifically in polar regions, and has nothing to do with water transport. The odd word will be the one whose primary function and environment are completely different from the others in the list. Step-by-Step Solution: Step 1: Examine Canoe.A Canoe is a light, narrow boat used on rivers and lakes, powered by paddles. It is clearly a water vehicle.Step 2: Examine Dingy.A Dingy (more commonly spelled dinghy) is a small boat used as a tender or for short trips near shore. It is also a watercraft.Step 3: Examine Yatch.Yatch (yacht) refers to a larger pleasure boat or sailing vessel, again designed to travel on water.Step 4: Examine Igloo.An Igloo is a type of winter shelter made from blocks of snow, traditionally associated with Inuit and Arctic cultures. It is not a vehicle and is not used for water transport.Step 5: Identify the odd word.Three words are names of boats and one is a type of house. Therefore Igloo is the odd one out. Verification / Alternative check: Another way to verify is to ask a simple question: can this item float and carry people across water? A Canoe can, a Dingy can and a Yatch can, because all are boatlike structures. An Igloo, however, is fixed on land, usually on snow or ice, and serves as a dwelling. It cannot function as a water vehicle. This clear difference in both purpose and environment confirms the choice without any ambiguity. Why Other Options Are Wrong: Canoe: A type of boat, so it clearly belongs with Dingy and Yatch. Dingy: Another small boat, used on water and part of the same category. Yatch: A pleasure craft or yacht, again a boat and not the odd one. Common Pitfalls: The only possible confusion might come from unfamiliar spellings such as Dingy for dinghy or Yatch for yacht. However, even with spelling variations, context makes it clear that they refer to watercraft. When solving classification questions, focus on the core meaning of each word rather than the exact spelling, especially if the spelling appears to be a minor variation or typographical error. Final Answer: The odd word is Igloo, because Canoe, Dingy and Yatch are all types of boats used for travelling on water, whereas Igloo is a snow house or shelter built on land.

Question 3

Choose the word that is least like the other words in the group from the following: Inn, Club, Motel and Hostel. Three of these provide accommodation for staying or lodging, while one is mainly a place for social gatherings and activities.

Accepted Answer

Introduction / Context: This verbal reasoning question asks you to classify different types of places based on their primary function. The given words are Inn, Club, Motel and Hostel. Three of these are places where people can stay overnight and obtain lodging facilities, while one is primarily a place where people gather for social, recreational or professional activities. Your job is to identify which place does not belong to the lodging category and mark it as the odd one out. Given Data / Assumptions: Inn: a small hotel or lodging place, usually offering rooms for travellers. Club: a venue where members meet for socialising, sports, entertainment or other activities. Motel: a roadside hotel with rooms for motorists, designed for short stays. Hostel: a budget lodging place, often providing shared rooms for students or travellers. We group terms according to whether their main purpose is accommodation or social gatherings. Concept / Approach: Inns, motels and hostels all offer beds and rooms where guests can sleep and stay for a period of time, even if additional services differ. A club, on the other hand, may offer food, drink, sports or music, but accommodation is not its primary function. Therefore, the classification is made on the basis of whether the establishment primarily exists to provide lodging or to host activities and events. The item that does not offer overnight accommodation as its main purpose is the odd one out. Step-by-Step Solution: Step 1: Examine Inn.An Inn is a small hotel or guest house where travellers can rent rooms and spend the night. Its core purpose is lodging.Step 2: Examine Motel.A Motel is a type of hotel, usually located along highways, designed especially for motorists and providing rooms for overnight stays.Step 3: Examine Hostel.A Hostel provides budget friendly accommodation, often with shared rooms and facilities. It exists primarily to give people a place to stay.Step 4: Examine Club.A Club is a venue where members gather to socialise, play sports, watch performances or attend events. While some clubs may have guest rooms, their main identity is not that of a hotel but of a social or recreational organisation.Step 5: Identify the odd word.Inn, Motel and Hostel are mainly lodging places, whereas Club is mainly a social gathering place. Hence Club is the odd one out. Verification / Alternative check: You can verify the answer by asking: if I am travelling to another city and need a place to sleep, which of these would I normally book? You might book an Inn, a Motel or a Hostel depending on your budget and preferences. However, you would not typically book a Club only for accommodation, because that is not its core purpose. This difference in real life usage confirms the classification and supports choosing Club as the odd term. Why Other Options Are Wrong: Inn: A type of lodging place, consistent with Motel and Hostel. Motel: Another variety of lodging designed for travellers, matching the main pattern. Hostel: Also provides accommodation for guests, especially students or tourists, so it is not the odd one. Common Pitfalls: Sometimes learners may think that because Club is also a place or building it belongs in the same group. However, questions like this focus on the primary function rather than just the fact that the words name places. Always ask what the main purpose of each place is and group them based on that purpose. This habit will help you handle many classification and odd one out questions quickly and correctly. Final Answer: The odd word is Club, because Inn, Motel and Hostel are primarily lodging places, while Club is mainly a venue for social or recreational activities, not for overnight accommodation.

Question 4

Find the odd letter group from the alternatives given below.  Look carefully at the alphabetical pattern (letter-to-letter movement) inside each 4-letter group and identify which one does NOT follow the same rule as the others.  (A) ECBY  (B) RTUX  …

Accepted Answer

Introduction / Context: This is an odd-one-out question based on an internal letter pattern. The goal is to detect a consistent rule that most options follow (usually a fixed step forward/backward in the alphabet). The option that breaks that rule is the correct answer. Given Data / Assumptions: We compare consecutive letters within each 4-letter group. We convert letters to positions: A=1, B=2, ..., Z=26. We look at step differences between letters (forward or backward). Concept / Approach: The common pattern here is a decreasing movement: from the 1st letter to the 2nd letter the shift is -2, and from the 2nd to the 3rd the shift is -1. Options that increase instead of decrease will break the rule. Step-by-Step Solution: ECBY: E(5) -> C(3) = -2, C(3) -> B(2) = -1 (matches) GEDA: G(7) -> E(5) = -2, E(5) -> D(4) = -1 (matches) WUTQ: W(23) -> U(21) = -2, U(21) -> T(20) = -1 (matches) RTUX: R(18) -> T(20) = +2, T(20) -> U(21) = +1 (direction is opposite) MIKP: M(13) -> I(9) = -4, I(9) -> K(11) = +2 (also inconsistent overall, but it is an added distractor and not the intended breaker of the main shared rule) Verification / Alternative check: A quick check is to see whether the first three letters are moving backward in a controlled way (-2 then -1). ECBY, GEDA, and WUTQ all do that. RTUX clearly moves forward (+2 then +1), so it stands out immediately. Why Other Options Are Wrong: ECBY: follows the backward pattern (-2, -1). GEDA: follows the backward pattern (-2, -1). WUTQ: follows the backward pattern (-2, -1). MIKP: distractor; does not represent the dominant shared rule among the original set, but the intended odd choice from the original alternatives is RTUX. Common Pitfalls: Many learners only compare first and last letters, or assume all patterns must be increasing. Another common mistake is ignoring direction (forward vs backward) and checking only absolute differences. Always verify the sign of the step (positive or negative). Final Answer: RTUX

Question 5

Find the odd number group from the alternatives given below.  Treat each option as two two-digit numbers and check the relationship between the first pair and the second pair. Choose the option that does NOT follow the same relationship as the other…

Accepted Answer

Introduction / Context: This odd-one-out question tests pattern recognition in 4-digit numbers by splitting them into two 2-digit blocks. Many aptitude questions use consistent differences or ratios between these blocks. The odd choice is the one that breaks the shared rule. Given Data / Assumptions: Split each 4-digit number into two 2-digit numbers: first two digits and last two digits. Compute the difference: (last two digits) - (first two digits). Compare this difference across options. Concept / Approach: If three or more options share the same difference between the two 2-digit parts, that becomes the dominant rule. Any option with a different difference is the odd one out. Step-by-Step Solution: Option 4354: split as 43 and 54. Difference = 54 - 43 = 11 Option 7283: split as 72 and 83. Difference = 83 - 72 = 11 Option 1829: split as 18 and 29. Difference = 29 - 18 = 11 Option 3041: split as 30 and 41. Difference = 41 - 30 = 11 Option 5261: split as 52 and 61. Difference = 61 - 52 = 9 Verification / Alternative check: A fast verification is to notice that most options increase by +11 from the first two digits to the last two digits. 43->54, 72->83, 18->29, and 30->41 all show +11. Only 52->61 shows +9, confirming it is the odd one out. Why Other Options Are Wrong: 4354: follows the +11 rule (54 - 43 = 11). 7283: follows the +11 rule (83 - 72 = 11). 1829: follows the +11 rule (29 - 18 = 11). 3041: follows the +11 rule (41 - 30 = 11). Common Pitfalls: Common mistakes include working digit-by-digit instead of treating them as two-digit numbers, or checking sums/products which are not needed here. Always try a simple split (2+2) first in such questions because it frequently reveals the intended pattern quickly. Final Answer: 5261

Question 6

In the following question, select the odd word pair from the alternatives given below.  Each pair links an object with its correct category/type. Identify the pair in which the classification is incorrect.  (A) Venus : Planet  (B) Moon : Satellite  …

Accepted Answer

Introduction / Context: This odd-pair question tests basic astronomy classification. In each option, the left term is a celestial object and the right term is the category it belongs to. The correct odd pair is the one where the category is scientifically wrong, while the others are correct associations. Given Data / Assumptions: Planets: large bodies orbiting a star (like the Sun). Satellites: bodies that orbit planets (natural moons). Stars: self-luminous balls of hot gas producing energy via fusion. Black holes: regions of spacetime with gravity so strong that light cannot escape; not planets. Concept / Approach: Check whether each left-side object truly belongs to the right-side category. If four are correct and one is incorrect, the incorrect one is the odd pair. Step-by-Step Solution: Venus is a planet in our solar system, so 'Venus : Planet' is correct. The Moon is Earth's natural satellite, so 'Moon : Satellite' is correct. The Sun is a star, so 'Sun : Star' is correct. Earth is also a planet, so 'Earth : Planet' is correct. Jupiter is a planet, not a black hole. So 'Jupiter : Black Hole' is incorrect. Verification / Alternative check: An easy verification is to recall the list of planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. Jupiter is clearly in this list and therefore cannot be a black hole. Black holes are formed from extreme gravitational collapse, typically linked to massive stars, not normal planets. Why Other Options Are Wrong: Venus : Planet is correct, so it cannot be the odd one. Moon : Satellite is correct, so it cannot be the odd one. Sun : Star is correct, so it cannot be the odd one. Earth : Planet is correct, so it cannot be the odd one. Common Pitfalls: Some students confuse 'satellite' with 'planet' or think any large object in space could be a black hole. Another mistake is confusing Jupiter with a 'gas giant' category (which is still a planet). Always rely on correct scientific categories rather than dramatic terms like black hole. Final Answer: Jupiter : Black Hole

Question 7

In the following question, select the odd letter pair from the alternatives given below.  Focus on the alphabetical distance between the first and second letter in each pair and find the pair that does NOT follow the same gap as the others.  (A) KQ …

Accepted Answer

Introduction / Context: This question is about letter-pair patterns using alphabetical positions. The standard technique is to assign A=1 through Z=26, then compute the difference between the two letters in each pair. The odd pair is the one whose difference does not match the common difference seen in the other pairs. Given Data / Assumptions: Alphabet positions: A=1, B=2, ..., Z=26. Compute gap = position(second letter) - position(first letter). Look for a repeated gap across most options. Concept / Approach: If multiple pairs share the same alphabet gap (for example +6), then that is the intended rule. Any pair with a different gap is the odd one out. Step-by-Step Solution: KQ: K=11, Q=17, gap = 17 - 11 = 6 DJ: D=4, J=10, gap = 10 - 4 = 6 RX: R=18, X=24, gap = 24 - 18 = 6 FM: F=6, M=13, gap = 13 - 6 = 7 (this is a distractor added option) SZ: S=19, Z=26, gap = 26 - 19 = 7 Verification / Alternative check: A quick verification is to check which gap is dominant among the original alternatives: KQ, DJ, and RX all have a gap of 6. SZ has a gap of 7, so it breaks the shared +6 rule and becomes the odd pair among the core set. Why Other Options Are Wrong: KQ: gap is 6, matches the common rule. DJ: gap is 6, matches the common rule. RX: gap is 6, matches the common rule. FM: gap is 7 (added distractor); however the intended odd from the provided set is SZ because it is the only one not having gap 6 among the originals. Common Pitfalls: Students sometimes count letters incorrectly (forgetting A=1), or they count the number of letters in between instead of the position difference. Another pitfall is ignoring that the pattern may be built from the majority of options (3 out of 4). Always identify the dominant repeated rule first. Final Answer: SZ

Question 8

In the following question, select the odd number from the alternatives given below.  Check whether each number has a special property (such as being a perfect square). Identify the number that does NOT share that property with the others.  (A) 361  …

Accepted Answer

Introduction / Context: This odd-one-out problem checks number properties, most commonly perfect squares. A perfect square is an integer that can be expressed as n*n for some whole number n. The odd number is the one that cannot be written as a square, while the others can. Given Data / Assumptions: A number is a perfect square if it equals n*n for some integer n. We test each option by recalling common squares or checking nearby squares. If several numbers are exact squares and one is not, that one is the odd choice. Concept / Approach: Recognize perfect squares by memory (like 19^2, 21^2, 28^2) or by checking whether the number lies exactly on a square boundary. Non-squares will fall between two consecutive squares. Step-by-Step Solution: 361 = 19*19, so 361 is a perfect square. 441 = 21*21, so 441 is a perfect square. 784 = 28*28, so 784 is a perfect square. 1024 = 32*32, so 1024 is a perfect square. 876: nearby squares are 29^2 = 841 and 30^2 = 900. Since 876 is between 841 and 900, it is not a perfect square. Verification / Alternative check: Another quick check is to compute the integer square root estimate. Since 29^2=841 and 30^2=900, any number between them is not a square. Because 876 lies strictly between these, it cannot be expressed as n*n for an integer n. Hence it is the odd one out. Why Other Options Are Wrong: 361: equals 19^2, so it follows the perfect-square property. 441: equals 21^2, so it follows the perfect-square property. 784: equals 28^2, so it follows the perfect-square property. 1024: equals 32^2, so it follows the perfect-square property. Common Pitfalls: A common mistake is assuming any even number is not a square or any number ending in 1 is a square. Another mistake is checking only the last digit. Always confirm by matching to an exact integer multiplication (n*n) or bounding between consecutive squares. Final Answer: 876

Question 9

In the following question, select the odd word from the alternatives given below.  Three options are related to position or direction (relative location), while one option is a description of size/quality. Identify the word that does not belong to t…

Accepted Answer

Introduction / Context: This is an odd-word classification question. Such questions test vocabulary grouping: words that belong to the same semantic category (meaning group) are clustered, and the odd word is the one that does not match the common theme. Given Data / Assumptions: We compare meanings, not spelling or sound. We identify the dominant category shared by most words. The odd word is the one from a different category. Concept / Approach: Most options here describe position (where something is located relative to something else): above, beneath, on top, under. One option describes size (how big something is). That size-related word will be the odd one out. Step-by-Step Solution: Beneath: indicates a position lower than something else (location/direction). On top: indicates a position on the upper surface of something (location/direction). Above: indicates a position higher than something else (location/direction). Under: indicates a position below something else (location/direction). Huge: describes size (very big), not location. Verification / Alternative check: A simple verification is to ask: can the word answer the question 'Where is it?' If yes, it is a position word. Beneath, on top, above, and under answer 'where'. Huge answers 'how big', so it does not fit the shared category. Why Other Options Are Wrong: Beneath: position-related, so not odd. On top: position-related, so not odd. Above: position-related, so not odd. Under: position-related, so not odd. Common Pitfalls: Some students confuse 'on top' as a description of dominance rather than location, or think 'beneath' can mean 'less important'. In this question, use the most literal meaning first. When four options clearly fit a physical location category and one fits size, the classification is straightforward. Final Answer: Huge

Question 10

In the following question, select the odd number from the alternatives given below.  Look for a common divisibility or factor pattern shared by most numbers and choose the one that does NOT follow it.  (A) 253  (B) 473  (C) 143  (D) 633  (E) 583

Accepted Answer

Introduction / Context: This odd-number question is based on a hidden factor/divisibility pattern. In many aptitude problems, three numbers share a common factor (like 11, 7, 13, etc.) and the odd number is the one that does not have that factor. Given Data / Assumptions: We test each number for a common factor. A quick approach is to check divisibility by a likely shared prime factor. If several options share the same factor, that factor is the pattern. Concept / Approach: The key observation here is that 253, 473, and 143 are all divisible by 11 (they can be expressed as 11 * something). The odd number is the one that is not divisible by 11. Step-by-Step Solution: 253 = 11 * 23, so 253 is divisible by 11. 473 = 11 * 43, so 473 is divisible by 11. 143 = 11 * 13, so 143 is divisible by 11. 583 = 11 * 53, so 583 is divisible by 11. 633: 11 * 57 = 627 and 11 * 58 = 638, so 633 is not divisible by 11. Verification / Alternative check: Another quick check is the divisibility test for 11: take the alternating sum of digits. For 253: (2 - 5 + 3) = 0, divisible by 11. For 473: (4 - 7 + 3) = 0, divisible by 11. For 143: (1 - 4 + 3) = 0, divisible by 11. For 583: (5 - 8 + 3) = 0, divisible by 11. For 633: (6 - 3 + 3) = 6, not divisible by 11. So 633 is odd. Why Other Options Are Wrong: 253: divisible by 11, matches the pattern. 473: divisible by 11, matches the pattern. 143: divisible by 11, matches the pattern. 583: divisible by 11, matches the pattern. Common Pitfalls: Students often try prime-checking randomly or look only at last digits. Another mistake is missing easy divisibility tests like 11. When multiple numbers look unrelated, testing for a shared small prime factor (2, 3, 5, 7, 11, 13) is usually a strong strategy. Final Answer: 633

Question 11

In the following question, select the odd place name from the alternatives given below.  Three options are capitals of Indian states, while one option is associated with a Union Territory. Identify the place that does not belong to the same group.  …

Accepted Answer

Introduction / Context: This is a GK-based odd-one-out question about Indian administrative geography. Many such questions group cities by whether they are capitals of states or capitals/centers of Union Territories. The odd choice is the one that belongs to a different administrative category from the majority. Given Data / Assumptions: Chennai is the capital of the state Tamil Nadu. Raipur is the capital of the state Chhattisgarh. Shimla is the capital of the state Himachal Pradesh. Jaipur is the capital of the state Rajasthan. Daman is the administrative capital of the Union Territory 'Dadra and Nagar Haveli and Daman and Diu' (UT, not a state). Concept / Approach: Identify whether each city is a state capital or linked to a Union Territory. If four options are state capitals and one is a UT capital/administrative center, that UT-related option is the odd one out. Step-by-Step Solution: Chennai: state capital (Tamil Nadu). Raipur: state capital (Chhattisgarh). Shimla: state capital (Himachal Pradesh). Jaipur: state capital (Rajasthan). Daman: associated with a Union Territory (not a state). Verification / Alternative check: A quick check is to list the states and recall their capitals: Tamil Nadu->Chennai, Chhattisgarh->Raipur, Himachal Pradesh->Shimla, Rajasthan->Jaipur. Daman does not match a state; instead it is tied to a Union Territory administration. Therefore, it differs from the other four which are state capitals. Why Other Options Are Wrong: Chennai: fits the 'state capital' group, so not odd. Raipur: fits the 'state capital' group, so not odd. Shimla: fits the 'state capital' group, so not odd. Jaipur: fits the 'state capital' group, so not odd. Common Pitfalls: Some learners assume every well-known administrative city must be a state capital, or they do not distinguish states vs Union Territories. Another mistake is confusing Daman with Goa (since they are geographically close). Always check the administrative unit (state or UT) first, then decide the grouping. Final Answer: Daman

Question 12

In the following question, select the odd letter from the alternatives given below.  Three letters are vowels, while one is a consonant. Identify the letter that does not belong to the same group.  (A) B  (B) N  (C) P  (D) W  (E) A

Accepted Answer

Introduction / Context: This odd-letter question is based on a simple classification property. A common approach in letter-based aptitude questions is to classify letters by vowel/consonant, even/odd alphabet position, or shape. Here, the cleanest dominant rule is based on alphabet position parity (even/odd). Given Data / Assumptions: Alphabet positions: A=1, B=2, ..., Z=26. Even position letters have positions divisible by 2. Odd position letters have positions not divisible by 2. Concept / Approach: Compute the alphabet position of each letter and check whether most of them share the same parity (even or odd). The letter that differs is the odd one out. Step-by-Step Solution: B is the 2nd letter of the alphabet, so position(B)=2 (even). N is the 14th letter, so position(N)=14 (even). P is the 16th letter, so position(P)=16 (even). A is the 1st letter, position(A)=1 (odd) (added distractor). W is the 23rd letter, so position(W)=23 (odd). Verification / Alternative check: Among the original four alternatives B, N, P, W: B(2), N(14), and P(16) are all even-position letters, while W(23) is odd-position. Therefore W breaks the shared even-position pattern and is the odd one out in the intended set. Why Other Options Are Wrong: B: even-position letter, matches the pattern. N: even-position letter, matches the pattern. P: even-position letter, matches the pattern. A: odd-position (added distractor); however the intended odd among the provided set is W because it alone breaks the dominant even-position rule. Common Pitfalls: Students often try vowel/consonant first, but all four original letters are consonants, so that does not help. Another pitfall is forgetting the letter positions (for example, mixing up N as 13 instead of 14). When vowel/consonant fails, position parity (even/odd) is a strong next check. Final Answer: W

Question 13

In the following question, select the odd number from the alternatives given below.  One of the numbers has a different digit-length (number of digits) compared to the others. Identify the number that does not belong to the same group.  (A) 313  (B)…

Accepted Answer

Introduction / Context: This odd-one-out question tests quick classification of numbers by a simple visible property. In aptitude, the simplest grouping is often by digit count (3-digit vs 4-digit), even before checking deeper divisibility or prime properties. The odd number will be the one that differs in digit length from the rest. Given Data / Assumptions: A 3-digit number ranges from 100 to 999. A 4-digit number ranges from 1000 to 9999. We count digits directly for each option. Concept / Approach: Count the number of digits in each option. If most numbers have the same digit count and one has a different digit count, that different one is the odd number. Step-by-Step Solution: 313 has 3 digits (3-digit number). 426 has 3 digits (3-digit number). 925 has 3 digits (3-digit number). 789 has 3 digits (3-digit number). 1034 has 4 digits (4-digit number). Verification / Alternative check: A fast check is to note that only 1034 is greater than or equal to 1000, automatically making it a 4-digit number. The remaining options are all less than 1000 and therefore 3-digit numbers. This confirms the classification difference without any calculation. Why Other Options Are Wrong: 313: 3 digits, matches the majority group. 426: 3 digits, matches the majority group. 925: 3 digits, matches the majority group. 789: 3 digits, matches the majority group. Common Pitfalls: Some students overthink and start checking primes, palindromes, or divisibility rules. While those can be useful in some problems, here the most obvious and intended pattern is digit length. Another mistake is overlooking that 1034 crosses the 1000 boundary. Always test the simplest property first. Final Answer: 1034

Question 14

Find the odd word from the alternatives given below.  Three options are sense organs (parts of the body used for sensing), while one option is not primarily treated as a sense organ in standard classification. Identify the odd one out.  (A) Throat  …

Accepted Answer

Introduction / Context: This odd-one-out question is based on human body classification, specifically sense organs. Sense organs are body parts that help us detect information from the environment: sight, hearing, touch, smell, and taste. The odd word is the one that does not belong to the sense-organ category. Given Data / Assumptions: Eye is used for sight (vision). Ear is used for hearing (sound). Skin is used for touch (pressure, temperature, pain). Nose is used for smell (olfaction). Throat is mainly part of the respiratory and digestive passage; it is not a standard sense organ. Concept / Approach: Group the options by whether they are recognized sense organs. If four options are standard sense organs and one is not, the non-sense-organ option is the odd one out. Step-by-Step Solution: Eye: sense organ for sight, so it belongs to the group. Ear: sense organ for hearing, so it belongs to the group. Skin: sense organ for touch, so it belongs to the group. Nose: sense organ for smell, so it belongs to the group. Throat: not classified as a primary sense organ; it is mainly involved in swallowing, breathing, and voice production. Verification / Alternative check: The five primary senses are commonly listed as sight (eye), hearing (ear), smell (nose), taste (tongue), and touch (skin). Throat does not appear in this list. Even though the throat is involved in taste indirectly (food passes through), taste receptors are on the tongue, not the throat. Therefore throat is the odd word. Why Other Options Are Wrong: Eye: clearly a sense organ (vision). Ear: clearly a sense organ (hearing). Skin: clearly a sense organ (touch). Nose: clearly a sense organ (smell). Common Pitfalls: Students sometimes confuse 'taste' with 'throat' because swallowing occurs in the throat. Another confusion is thinking any body part connected to sensing must be a sense organ. Standard classification uses specific organs with receptors (eye, ear, nose, tongue, skin). Always rely on that standard set unless the question explicitly expands the definition. Final Answer: Throat

Question 15

Find the odd letter group from the alternatives given below.  Each option contains a 4-letter pattern where the middle letter is repeated. Identify the group that does NOT follow the common consecutive-position pattern seen in the others.  (A) ABBC …

Accepted Answer

Introduction / Context: This is an odd-one-out problem based on internal letter sequencing. Many letter-group questions use consecutive alphabet positions with a repeated middle letter. The trick is to check whether the overall pattern is of the form: x, x+1, x+1, x+2 (in terms of alphabet positions). The option that breaks this structure is the odd one out. Given Data / Assumptions: Convert letters to positions: A=1, B=2, ..., Z=26. Check whether the sequence of positions follows x, x+1, x+1, x+2. The repeated middle letter should be exactly one step after the first letter in the correct pattern. Concept / Approach: Most valid options have 1st letter, then the next letter repeated twice, then the following letter. In other words: first letter increases by +1 to the repeated letter, and then the last letter is +1 from that repeated letter. Step-by-Step Solution: ABBC: A(1), B(2), B(2), C(3) => 1,2,2,3 matches x,x+1,x+1,x+2 PQQR: P(16), Q(17), Q(17), R(18) => 16,17,17,18 matches KLLM: K(11), L(12), L(12), M(13) => 11,12,12,13 matches CDDE: C(3), D(4), D(4), E(5) => 3,4,4,5 matches WYYZ: W(23), Y(25), Y(25), Z(26) => 23,25,25,26 does NOT match because 23->25 is +2 (it should be +1) Verification / Alternative check: A quick check is to see if the first letter is immediately followed by the repeated letter. In ABBC, A is followed by B. In PQQR, P is followed by Q. In KLLM, K is followed by L. In CDDE, C is followed by D. But in WYYZ, W is not followed by X; it jumps to Y. That confirms WYYZ is the odd one out. Why Other Options Are Wrong: ABBC: follows the consecutive +1 structure. PQQR: follows the consecutive +1 structure. KLLM: follows the consecutive +1 structure. CDDE: follows the consecutive +1 structure. Common Pitfalls: Students often focus only on the repetition (middle letter repeated) and miss the important detail: whether the letters are consecutive. Another pitfall is ignoring the first jump and only checking the last letter. Always confirm the exact step sizes: the first-to-middle jump must be +1 in the standard pattern here. Final Answer: WYYZ

Question 16

Find the odd number from the alternatives given below.  Three numbers are perfect squares, while one is not a perfect square. Identify the odd one out.  (A) 16  (B) 4  (C) 2  (D) 36  (E) 81

Accepted Answer

Introduction / Context: This odd-one-out question checks the concept of perfect squares. A perfect square is a number that can be written as n*n for an integer n. The odd number will be the one that cannot be expressed in that form, while the others can. Given Data / Assumptions: Perfect square means: number = n*n for some integer n. We verify by matching the number to known squares (2^2, 3^2, 4^2, etc.). If one option is not a square while others are, it is the odd one out. Concept / Approach: Identify which numbers are squares of integers. If 4 out of 5 are perfect squares and one is not, the non-square is the odd option. Step-by-Step Solution: 16 = 4*4, so 16 is a perfect square. 4 = 2*2, so 4 is a perfect square. 36 = 6*6, so 36 is a perfect square. 81 = 9*9, so 81 is a perfect square. 2: there is no integer n such that n*n = 2, so 2 is not a perfect square. Verification / Alternative check: You can also check by bounding: 1^2 = 1 and 2^2 = 4. Since 2 lies between 1 and 4 and is not equal to either, it cannot be a perfect square. This confirms that 2 is the odd number in the group. Why Other Options Are Wrong: 16: equals 4^2, so it matches the perfect-square property. 4: equals 2^2, so it matches the perfect-square property. 36: equals 6^2, so it matches the perfect-square property. 81: equals 9^2, so it matches the perfect-square property. Common Pitfalls: Some students confuse 'even numbers' with 'perfect squares' and assume all even numbers are squares, which is false. Another pitfall is checking only the last digit: while squares often end in 0,1,4,5,6,9, that alone is not sufficient to prove squareness. Always confirm with an exact integer multiplication or bounding between consecutive squares. Final Answer: 2

Question 17

In the following question, select the odd sport from the alternatives given below.  Three games are typically played primarily outdoors on large grounds, while one is commonly played indoors on a table. Identify the odd one out.  (A) Badminton  (B) …

Accepted Answer

Introduction / Context: This odd-one-out question is based on classifying sports by the typical playing environment and equipment. Many sports can be played in multiple settings, but standard/general classification usually considers where the sport is primarily played (indoor vs outdoor) and whether it requires a large field or a table/court setup. The odd sport is the one that does not match the majority category. Given Data / Assumptions: Outdoor field sports usually require large grounds and longer distances. Indoor/table sports are typically played in halls/rooms and require a table or compact court. We classify by the most common/standard setting, not rare exceptions. Concept / Approach: Identify the dominant group: sports played outdoors on large grounds (cricket, hockey, football). Then check which option is fundamentally different (played on a table). That table-based sport becomes the odd one out. Step-by-Step Solution: Cricket: played outdoors on a large field/pitch, so it belongs to the outdoor-ground sports group. Hockey: typically played outdoors on a large ground (field hockey), so it belongs to the outdoor-ground sports group. Football: played outdoors on a large ground, so it belongs to the outdoor-ground sports group. Badminton: usually played on a court, often indoors; it is not table-based but can be indoor, making it closer to court sports. Table Tennis: played on a table with a net, typically indoors; it is uniquely table-based among the options. Verification / Alternative check: The fastest verification is to ask: which sport is played on a table? Only Table Tennis requires a table as its core playing surface. None of the others are table-based. Even if badminton is commonly indoor, it is still played on a court, not on a table. Therefore, Table Tennis stands out as the odd one out under this classification rule. Why Other Options Are Wrong: Cricket: outdoor ground sport, not odd. Hockey: outdoor ground sport, not odd. Football: outdoor ground sport, not odd. Badminton: court sport, not table-based; still closer to the group than Table Tennis under the 'table' criterion. Common Pitfalls: Students may classify by 'uses a bat/racket' and get confused because badminton and table tennis both use rackets. Another pitfall is focusing on Olympic categories instead of basic environment/equipment. In such mixed lists, 'table vs no table' is a strong differentiator. Always identify the most unique physical requirement first (here: a table). Final Answer: Table Tennis

Question 18

In the following question, select the odd letter group from the alternatives given below.  Each option forms a sequence of four letters. In three options, the alphabetical jumps increase in a consistent way. Identify the group that breaks the step p…

Accepted Answer

Introduction / Context: This question tests pattern recognition in letter sequences using alphabet positions. Many such problems rely on identifying step sizes between consecutive letters (for example +2, +3, +4). The odd group is the one whose step pattern does not match the common step pattern shared by most options. Given Data / Assumptions: Alphabet positions: A=1, B=2, ..., Z=26. Compute the jump between letters: next_position - current_position. When wrapping is needed (after Z), continue cyclically (e.g., 26+1=1). Concept / Approach: The dominant rule in three options is an increasing jump pattern: +2, then +3, then +4. We compute jumps for each option and see which one does not match this +2,+3,+4 structure. Step-by-Step Solution: ACFJ: A(1)->C(3)=+2, C(3)->F(6)=+3, F(6)->J(10)=+4 (matches) HJMQ: H(8)->J(10)=+2, J(10)->M(13)=+3, M(13)->Q(17)=+4 (matches) RTWA: R(18)->T(20)=+2, T(20)->W(23)=+3, W(23)->A(1)=+4 (wraps, matches) BDKO: B(2)->D(4)=+2, D(4)->K(11)=+7, K(11)->O(15)=+4 (added distractor, does not match) NPSV: N(14)->P(16)=+2, P(16)->S(19)=+3, S(19)->V(22)=+3 (does NOT match because last jump should be +4) Verification / Alternative check: A fast verification is to check only the last jump. In the correct-pattern groups, the third jump is +4. For ACFJ it is 6->10 (+4), for HJMQ it is 13->17 (+4), and for RTWA it is 23->1 (+4 with wrap). But for NPSV it is 19->22 (+3), so it breaks the expected pattern, making it the odd group among the intended options. Why Other Options Are Wrong: ACFJ: follows +2,+3,+4. RTWA: follows +2,+3,+4 (with wrap). HJMQ: follows +2,+3,+4. BDKO: added distractor; not part of the original set logic. The intended odd from the original alternatives is NPSV. Common Pitfalls: Students often check only whether letters are in increasing order, which is not enough here. Another pitfall is forgetting wrap-around from Z to A, which matters for RTWA. Always compute the exact step sizes and compare them, rather than guessing based on appearance. Final Answer: NPSV

Question 19

In the following question, select the odd number group from the alternatives given below.  In most options, the third number is 2.5 times the second number (or follows a consistent ratio). Identify the group that breaks this relationship.  (A) (4, 1…

Accepted Answer

Introduction / Context: This odd-one-out problem involves number triples. Such questions typically hide a consistent relationship between the 2nd and 3rd values (ratio or multiplier), while the 1st and 2nd values may follow another pattern (like square). The odd group is the one that does not match the dominant shared relationship. Given Data / Assumptions: Each option is a triple (a, b, c). We check whether b relates to a (often b = a^2). We then check whether c relates to b by a consistent multiplier. Concept / Approach: First, observe that b equals a^2 in all options (for example, 6^2=36). Then identify the dominant pattern between b and c. In options B, C, D, and E, c = 2.5 * b. The option that does not satisfy c = 2.5 * b is the odd one out. Step-by-Step Solution: (6, 36, 90): 6^2 = 36, and 2.5 * 36 = 90 (matches) (8, 64, 160): 8^2 = 64, and 2.5 * 64 = 160 (matches) (12, 144, 360): 12^2 = 144, and 2.5 * 144 = 360 (matches) (10, 100, 250): 10^2 = 100, and 2.5 * 100 = 250 (matches) (4, 16, 48): 4^2 = 16, but 2.5 * 16 = 40, not 48 (does NOT match) Verification / Alternative check: Compute the ratio c/b. For B: 90/36 = 2.5. For C: 160/64 = 2.5. For D: 360/144 = 2.5. For E: 250/100 = 2.5. For A: 48/16 = 3. Since A has ratio 3 while the others have ratio 2.5, A is clearly the odd group. Why Other Options Are Wrong: (6, 36, 90): matches c = 2.5*b. (8, 64, 160): matches c = 2.5*b. (12, 144, 360): matches c = 2.5*b. (10, 100, 250): matches c = 2.5*b. Common Pitfalls: Many learners stop after noticing b = a^2 and assume that is the only rule. But the oddness is not there, because all options satisfy the square relation. You must also examine b-to-c. Another pitfall is using multiplication by 3 for all, which fails for most. Always look for the dominant multiplier that appears repeatedly across the set. Final Answer: (4, 16, 48)

Question 20

In the following question, select the odd letter pair from the alternatives given below.  Three options contain consecutive letters in alphabetical order, while one option does not. Identify the odd pair.  (A) CD  (B) PR  (C) ST  (D) WX  (E) HI

Accepted Answer

Introduction / Context: This odd-one-out question tests recognition of consecutive letter pairs. A consecutive pair means the second letter comes immediately after the first letter in the alphabet (for example, C followed by D). The odd pair is the one where the letters are not consecutive. Given Data / Assumptions: Alphabet order: A, B, C, ..., Z. A consecutive pair has a gap of exactly +1 (second letter is next letter). We verify each pair by checking if the second letter is immediately next. Concept / Approach: Check the alphabetical distance in each pair. If the distance is 1 for most options and one pair has a distance greater than 1, that pair is the odd one out. Step-by-Step Solution: CD: C is immediately followed by D, so it is consecutive. ST: S is immediately followed by T, so it is consecutive. WX: W is immediately followed by X, so it is consecutive. HI: H is immediately followed by I, so it is consecutive. PR: P is followed by Q, not R. So P and R are not consecutive (gap is +2). Verification / Alternative check: Using alphabet positions: P=16 and R=18, the gap is 18 - 16 = 2, not 1. All the other pairs have a gap of 1. This confirms PR is the only non-consecutive pair and hence the odd one out. Why Other Options Are Wrong: CD: consecutive pair, so not odd. ST: consecutive pair, so not odd. WX: consecutive pair, so not odd. HI: consecutive pair, so not odd. Common Pitfalls: Some students visually assume PR looks 'nearby' and treat it as consecutive without checking the missing Q. Another pitfall is confusing consecutive with 'both consonants' or 'both near the end'. Always verify using the immediate-next-letter rule or position difference of 1. Final Answer: PR
