IBPS RRB Clerk Prelims 2024 Reasoning Questions with Solutions

Explanation

From the given statement, combining Z = W ≤ D < U yields Z < U, which means U > Z is definitely true. For conclusion II, combining X ≥ E > Z = W yields X > W, so X is strictly greater than W, which means equal to W is not possible and X ≥ W is false.

Explanation

From the statement Q ≤ R = S, the relationship between Q and S directly gives Q ≤ S, making conclusion I true. From R = S ≥ B ≥ U > V, comparing R and V gives R > V, which is equivalent to V < R, making conclusion II true.

Explanation

In the chain G > H ≥ A = C < K, the presence of both greater-than and less-than signs between G and K means no definite relationship exists. Therefore, G can be greater than, less than, or equal to K. Conclusion I represents G ≤ K and Conclusion II represents G > K, covering all possible mathematical relations between the two variables.

Explanation

Arranging the birth dates in chronological order gives 9 January, 26 January, 9 February, 26 February, 9 March, and 26 March. Placing D on 9 January and two persons before A puts A on 26 February. Placing B on 26 January puts F three persons after B on 9 March, and E just younger than F on 26 March. This leaves C to be born on 9 February.

Explanation

The chronological order of births is D on 9 January, B on 26 January, C on 9 February, A on 26 February, F on 9 March, and E on 26 March. Since E is the youngest person born in the last position, exactly five persons were born before E, which is more than three.

Explanation

According to the chronological arrangement, D was born on 9 January, followed immediately by B who was born on 26 January.

Explanation

The order of births from youngest to oldest is E on 26 March, F on 9 March, A on 26 February, C on 9 February, B on 26 January, and D on 9 January. Counting from the youngest, A is the third youngest person.

Explanation

The chronological order of births is D on 9 January, B on 26 January, C on 9 February, A on 26 February, F on 9 March, and E on 26 March. Exactly two persons, D and B, are older than C.

Explanation

In the word 'REBUILT', the letters R and U are in positions 1 and 4 respectively, with 2 letters (E, B) between them. In the English alphabet, R is 18th and U is 21st, with 2 letters (S, T) between them. Thus, (R, U) is the only pair that satisfies the given condition.

Explanation

Since some animals are dogs and all dogs are loyal, the animals that are dogs must be loyal, which guarantees that some loyal entities are animals. However, since only the animals that are dogs are known to be loyal, other animals may or may not be friendly, so conclusion II does not necessarily follow.

Explanation

The statement "Only fruits are apples" means all apples are fruits and apples cannot be part of any category other than fruits, so Conclusion I is false. Since "Some fruits are sweet" and "All sweet is healthy", it is a definite fact that some fruits are healthy, making the possibility statement in Conclusion II logically false.

Explanation

Since only a few colorful are trees, birds can reside entirely in the part of colorful that is not a tree, making Conclusion I a valid possibility. Furthermore, all birds are colorful and no birds are rare, which guarantees that those colorful elements which are birds are definitely not rare, making Conclusion II definitely true.

Explanation

No definite relationship is given between gadget and music, so Conclusion I does not follow. The statement "Only a few device is item" inherently means both "Some devices are items" and "Some devices are not items", making Conclusion II definitely true.

Explanation

Counting the letters in the given series from left to right: 1: F, 2: T, 3: O, 4: W, 5: U, 6: G, 7: V, 8: D, 9: B, 10: H, 11: J. Thus, the 11th letter from the left end is J.

Explanation

The letters located to the left of H in the given series are F, T, O, W, U, G, V, D, and B. The first half of the alphabetical series consists of letters from A to M (positions 1 to 13). Among the letters to the left of H, F (6th), G (7th), D (4th), and B (2nd) belong to the first half, giving a total of four such letters.

Explanation

Removing all vowels (O, U, A, E, I) leaves 18 consonants in sequence: F, T, W, G, V, D, B, H, J, K, Z, N, M, S, C, R, X, P. The 6th letter from the right end is M. Moving 3 positions to its left corresponds to the 9th letter from the right end, which is K.

Explanation

The sequence of letters between A and I is K, Z, N, O, M, S, E, C, R, X, P. Extracting only the consonants gives 9 letters: K, Z, N, M, S, C, R, X, P. The middle (5th) consonant in this ordered list is S.

Explanation

We search for the pattern Vowel-Consonant-Consonant (VCC) in the series. The four matching instances are: U-G-V (consonant G) A-K-Z (consonant K) O-M-S (consonant M) E-C-R (consonant C) Therefore, there are four such consonants.

Explanation

Based on the buying order conditions, placing P at position 1 and using the relative symmetry constraint (pos(V) + pos(Q) = 8) alongside the gap constraints uniquely places the persons in sequence 1 to 7 as: 1-P, 2-U, 3-Q, 4-S, 5-V, 6-R, 7-T. The person buying immediately after P is U, who corresponds to the benchmark count of 324 pens.

Explanation

From the relative ordering of pen counts, U holds the 2nd highest rank with 324 pens. Since Q buys just fewer pens than the person with 324 pens, Q occupies the position immediately below U in the pen count ranking, making Q the person who buys the 3rd highest number of pens.

Explanation

Arranging the persons in descending order of pens bought: P (1st), U (2nd with 324 pens), Q (3rd), S (4th), V (5th), R (6th), and T (7th). Since the difference between U and V is 68, V buys 324 − 68 = 256 pens. Given that the difference between T and V is 50, T buys 256 − 50 = 206 pens. As R is ranked between V and T, the number of pens R buys must be strictly between 206 and 256. The value 251 satisfies this range.

Explanation

The order of persons from highest to lowest pens is P, U, Q, S, V, R, T. In the given pairs, P and Q, S and U, V and Q, and V and T each have exactly one person sitting between them in the sequence. The pair R and T consists of two adjacent persons with zero persons between them, making it the odd one out.

Explanation

From the position hierarchy P (1st) > U (2nd) > Q (3rd) > S (4th) > V (5th) > R (6th) > T (7th): Statement I is true because Q is ranked higher than R, meaning Q buys more pens than R. Statement II is false because V buys 256 pens, not 392 pens. Statement III is true because T is at the bottom of the order and thus buys the fewest pens. Therefore, statements I and III are correct.

Explanation

Extracting the specified letters from the word FAILURE: 1st letter = F 3rd letter = I 5th letter = U 6th letter = R The available letters are F, I, U, and R. No meaningful four-letter English word can be formed using each of these letters exactly once. According to the instructions, when no meaningful word can be formed, the code X must be marked.

Explanation

Comparing statement 1 and statement 2, the word "work" is common and corresponds to the code "zx". Substituting "work" = "zx" into statement 2 ("Is work" = "zx pt"), the remaining word "Is" corresponds directly to "pt".

Explanation

From statements 1, 2, and 4, we establish: work = zx assignments = iu deadlines = qs meetings = gr In statement 3 ("management deadlines policies meetings" = "qs rt mh gr"), removing "deadlines" (qs) and "meetings" (gr) leaves the words "management" and "policies" matched to the codes "rt" and "mh". Thus, the code for "management" is either "rt" or "mh".

Explanation

In statement 1 ("Given deadlines work assignments" = "zx iu vs qs"): work = zx assignments = iu deadlines = qs Removing these three pairs leaves the word "Given" uniquely coded as "vs".

Explanation

The code for "deadlines" is "qs" and the code for "meetings" is "gr". The word "policies" shares its code with "management", meaning its code can be either "rt" or "mh". Consequently, "deadlines policies meetings" can be represented by either "qs rt gr" or "qs mh gr". Since neither combination is uniquely resolved, the code cannot be determined.

Explanation

The word "Given" is coded as "vs". The word "management" is coded as either "rt" or "mh". Therefore, a possible code combination for "Given management" is "vs rt" or "vs mh". Among the choices provided, "vs rt" represents a valid combination.

Explanation

The building has 7 floors numbered 1 to 7 from bottom to top. L lives on an even floor but not 6, so L is on floor 2 or 4. Since J lives immediately above K and J lives on an odd floor, (J, K) can occupy floors (7, 6). Placing L on floor 4 and M on floor 2 creates a gap of one floor (floor 3) between L and M. H lives above M and below I, so with M on floor 2, H is on floor 3 and I is on floor 5. N occupies floor 1, completing the valid order from floor 7 to 1 as J, K, I, L, H, M, N. Thus, M lives on the 2nd floor.

Explanation

Placing the persons floor by floor from the given clues yields the arrangement: N on floor 1, M on floor 2, H on floor 3, L on floor 4, I on floor 5, K on floor 6 and J on floor 7. H lives on floor 3 and N lives on floor 1, so only floor 2, occupied by M, lies between their floors. Hence exactly one person lives between H and N.

Explanation

Using the clues -- L on an even floor other than 6, exactly one person between L and M, J immediately above K on an odd floor, and H strictly between M and I -- the only consistent arrangement is N-1, M-2, H-3, L-4, I-5, K-6, J-7. Hence H lives on the third floor.

Explanation

The arrangement derived from the clues places N on floor 1, M on floor 2, H on floor 3, L on floor 4, I on floor 5, K on floor 6 and J on floor 7. Since N is on the ground floor, statement (c) is true. N is not immediately above M (N is below M), L lives above N rather than below, and there are four persons between N and K rather than three, so the remaining statements are false.

Explanation

From the floor layout, J lives on floor 7 and I lives on floor 5. Only K lives on floor 6 between them, making the total count equal to 1.

Explanation

Changing the vowels A and O to their immediate next letters yields B and P. Changing the consonants H, R, M, N, and Y to their immediate previous letters yields G, Q, L, M, and X. The resulting word consists of the letters G, B, Q, L, P, M, and X, all of which are distinct, meaning no letter is repeated twice.

Explanation

Setting point Q at the origin (0, 0), walking 7m east leads to P (7, 0). Turning right (south) 5m gives F (7, -5), turning left (east) 4m gives G (11, -5), turning left (north) 6m gives D (11, 1), turning right (east) 8m gives M (19, 1), and turning left (north) 3m gives E (19, 4). Since both x and y coordinates of E relative to Q are positive, E lies in the northeast direction from Q.

Explanation

Point G has coordinates (11, -5) and point M has coordinates (19, 1). The horizontal distance Δx is 19 - 11 = 8m and the vertical distance Δy is 1 - (-5) = 6m. Using the Pythagorean theorem, the shortest distance is √(8² + 6²) = √(64 + 36) = √100 = 10m.

Explanation

The distance from point P to point F is 5m, from F to G is 4m, from G to D is 6m, and from D to M is 8m. Adding these path lengths together gives 5 + 4 + 6 + 8 = 23m.

Explanation

In the pair G-Q, point Q is located in the northwest direction relative to point G, whereas in every other pair the second point lies in the northeast direction relative to the first point.

Explanation

In KMO, the third letter O is not the reverse alphabet opposite of the second letter M, whereas in all other letter triplets the second letter is formed by adding 2 positions to the first letter and the third letter is the reverse alphabet opposite of the second.

Explanation

In the circular arrangement facing inside, the clockwise order of persons is U, T, Y, S, W, V, X, R. The opposite pairs in this seating arrangement are U and W, T and V, Y and X, and S and R. Therefore, U and X do not form an opposite pair, unlike all the other given options.

Explanation

With eight persons facing the center in the clockwise order U, T, Y, S, W, V, X, R, facing inside means left corresponds to the counter-clockwise direction. Since S is positioned immediately before W in clockwise order, S sits to the immediate left of W.

Explanation

In the circular arrangement facing inside, the clockwise seating sequence is U, T, Y, S, W, V, X, R. Adjacent positions are occupied by immediate neighbours. Here, T sits at position 2 and Y sits at position 3, making them immediate neighbours.

Explanation

In the circular arrangement with clockwise order U, T, Y, S, W, V, X, R, facing inside means moving left corresponds to counter-clockwise movement. Starting from X and moving three positions counter-clockwise passes through V and W to reach S. Hence, S sits third to the left of X.

Explanation

In the circular arrangement with clockwise order U, T, Y, S, W, V, X, R, facing center means right is clockwise and left is counter-clockwise. The person sitting to the immediate right of W is V. Moving three positions to the left (counter-clockwise) from V leads to Y.

Explanation

Extracting all even numbers from the given alphanumeric series yields 2, 6, 6, 2, 4, 4, and 8. Summing these values: 2 + 6 + 6 + 2 + 4 + 4 + 8 = 32.

Explanation

Checking each number for the Letter-Number-Letter pattern gives six such instances: G 6 H, K 7 W, W 6 M, M 2 Q, Q 4 E, and U 8 Y. Since 6 is greater than 5, the count falls under more than five.

Explanation

The given series consists of 29 elements in total. The tenth element from the right end corresponds to the twentieth element from the left end (29 - 10 + 1 = 20). Counting to the twentieth position from the left gives 3.

Explanation

Removing all numbers from the alphanumeric sequence leaves the letter sequence D, G, H, I, K, W, Q, E, R, U, Y, M, N. Counting from the left end, the sixth letter in this sequence is W.

Explanation

In the given series, K is at position 10 and 3 is at position 20. The nine elements lying strictly between them are 7, W, 6, M, 2, Q, 4, E, 5. The middle element of these nine items is 2, which has four elements on its left and four on its right.
