IBPS RRB Clerk Prelims 2024 Reasoning Questions with Solutions

Explanation

Only a few tops are Shirts implies some tops are shirts and some tops are not shirts. The statement that some tops are not Jeans allows the possibility that all Jeans are enclosed within Shirts without violating any given condition, making conclusion II a valid possibility. Conclusion I does not follow because no direct relationship between Hats and Tops is established.

Explanation

Only a few Ships are Submarine means that all Ships can never be Submarine, so conclusion I cannot be true. There is no definite intersection established between Boats and Motorboat, so conclusion II does not follow either.

Explanation

Since all Kanpur are Delhi and no Kanpur is Jaipur, the portion of Delhi that consists of Kanpur can never be Jaipur, which guarantees that some Delhi are not Jaipur. No direct relationship is specified between Kanpur and Panipat, so conclusion II does not definitely follow.

Explanation

Arranging the six persons according to the clues gives the sequential order from rank 1 to rank 6 as I, F, H, G, E, J. Since E is ranked 5th, exactly 4 persons purchase books before E.

Explanation

The sequential order of book purchases from rank 1 to rank 6 is I, F, H, G, E, J. Therefore, G purchases the book at the fourth rank from the start.

Explanation

The original order from rank 1 to rank 6 is I, F, H, G, E, J. Arranging the persons in alphabetical order gives E, F, G, H, I, J. Comparing position by position, F remains at rank 2 and J remains at rank 6, so exactly two persons keep their positions unchanged.

Explanation

In the order I, F, H, G, E, J, four persons purchase books between I (1st) and J (6th), making statement II true. Also, G (4th) purchases before E (5th), making statement III true. Statement I is false because I purchases before F.

Explanation

F purchases the book at rank 2, leaving 1 person purchasing before F. Similarly, E purchases the book at rank 5, leaving 1 person purchasing after E.

Explanation

Multiplying the digits for each number yields 5 × 3 × 4 = 60 for 534, 2 × 1 × 8 = 16 for 218, 3 × 5 × 6 = 90 for 356, 8 × 7 × 8 = 448 for 878, and 4 × 2 × 7 = 56 for 427. Arranging these products in ascending order gives 16, 56, 60, 90, 448, so the second lowest product corresponds to 427.

Explanation

Arranging the numbers in ascending order gives 218, 356, 427, 534, 878. The second lowest number is 356, whose highest digit is 6. The third highest number is 427, whose lowest digit is 2. The difference is 6 − 2 = 4.

Explanation

When the digits of each three-digit number are arranged in ascending order, 534 becomes 345, 218 becomes 128, 356 remains 356, 878 becomes 788, and 427 becomes 247. Thus, only 356 remains unchanged.

Explanation

The third number from the left end is 356, whose third digit is 6. The second number from the right end is 878, whose second digit is 7. Summing these two digits gives 6 + 7 = 13.

Explanation

Interchanging the first and third digits transforms 534 to 435, 218 to 812, 356 to 653, 878 to 878, and 427 to 724. Only 878 has equal first and third digits and therefore remains unchanged.

Explanation

In the word COMPLEX, the letters O (15th alphabetical position) and L (12th alphabetical position) have two letters between them (M and P), which matches the two letters (M and N) between L and O in the English alphabet. No other letter pair satisfies this condition.

Explanation

Since O sits at an end and Q sits sixth to its right, O must be at position 1 and Q at position 7. N is at position 2 (immediately right of O), M is at position 5 (N is third to M's left), and K is at position 11 (five persons right of M). Since K is second from the right end, the total number of persons in the row is 11 + 1 = 12, with S occupying the rightmost position 12.

Explanation

From the linear row arrangement, S occupies position 12 at the extreme right end and M occupies position 5. Subtracting the positions gives 12 - 5 = 7, which means M is situated seventh to the left of S.

Explanation

In the arrangement, Q is at position 7 and K is at position 11, leaving 3 persons (positions 8, 9, 10) between them. Similarly, O is at position 1 and M is at position 5, leaving 3 persons (positions 2, 3, 4) between O and M.

Explanation

Setting Point X as origin (0, 0), Point Y is (10, 0), Point Z is (10, -15), Point W is (17, -15), Point V is (17, -11), Point U is (22, -11), Point T is (22, 0), and Point S is (17, 0). Since Point W (17, -15) is 7m west of B, B is located at (24, -15). From B (24, -15) to T (22, 0), the movement is to the left (-2 in x) and upward (+15 in y), which corresponds to the north-west direction.

Explanation

Point Y is located at coordinates (10, 0) and Point S is located at coordinates (17, 0). Since both points lie on the same horizontal line, the shortest distance between them is |17 - 10| = 7m.

Explanation

The path traversed by Viraj from Point Z to Point T consists of four straight segments: Z to W (7m), W to V (4m), V to U (5m), and U to T (11m). Adding these distances yields a total distance of 7 + 4 + 5 + 11 = 27m.

Explanation

Arranging the eight persons according to the clues gives two rows: Row 2 (facing South, West to East): R at position 1, Q at position 2, S at position 3, P at position 4. Row 1 (facing North, West to East): D at position 1, A at position 2, C at position 3, B at position 4.

The person sitting opposite to Q is A (at position 2 in Row 1). Facing North, position 4 (where B sits) is two positions to the right of position 2 (where A sits). Therefore, B is second to the right of the person facing Q.

Explanation

Arranging the eight persons according to the clues gives two rows: Row 2 (facing South, West to East): R at position 1, Q at position 2, S at position 3, P at position 4. Row 1 (facing North, West to East): D at position 1, A at position 2, C at position 3, B at position 4.

The person facing B is P (at position 4 in Row 2). R sits at position 1 facing South, so the person immediately to the left of R (towards East) is Q at position 2. S sits at position 3, which is directly between Q at position 2 and P at position 4, meaning exactly one person sits between them.

Explanation

Arranging the eight persons according to the clues gives two rows: Row 2 (facing South, West to East): R at position 1, Q at position 2, S at position 3, P at position 4. Row 1 (facing North, West to East): D at position 1, A at position 2, C at position 3, B at position 4.

The extreme ends of Row 2 are occupied by R (position 1) and P (position 4). The extreme ends of Row 1 are occupied by D (position 1) and B (position 4). S occupies an inner position (position 3 in Row 2), making S the odd one out.

Explanation

Arranging the eight persons according to the clues gives two rows: Row 2 (facing South, West to East): R at position 1, Q at position 2, S at position 3, P at position 4. Row 1 (facing North, West to East): D at position 1, A at position 2, C at position 3, B at position 4.

P is at position 4 in Row 2 facing South. Counting three places to the right (towards West/lower positions) from P leads to S (1st right), Q (2nd right), and R (3rd right at position 1). Since D is at position 1 in Row 1, R is the person sitting opposite to D.

Explanation

Arranging the eight persons according to the clues gives two rows: Row 2 (facing South, West to East): R at position 1, Q at position 2, S at position 3, P at position 4. Row 1 (facing North, West to East): D at position 1, A at position 2, C at position 3, B at position 4.

The relationship connects R at position 1 in Row 2 to A at position 2 in Row 1, and S at position 3 in Row 2 to B at position 4 in Row 1. This establishes a mapping from position x in Row 2 to position x+1 in Row 1. Since C sits at position 3 in Row 1, the corresponding person in Row 2 at position 2 is Q.

Explanation

All Karate is inside Boxing, No Judo is Wrestling, and Only a few Boxing are Wrestling (meaning some Boxing are Wrestling and some Boxing are not Wrestling).

Karate can overlap with Judo in the area of Boxing that is not Wrestling, so Conclusion I ("Some Karate can be Judo") is a valid possibility. However, because some Boxing is definitely Wrestling and no Wrestling can be Judo, it is impossible for All Boxing to be Judo. Thus, Conclusion II does not follow.

Explanation

The statement "Only a few Birds are Peacock" logically incorporates two definite facts: Some Birds are Peacock AND Some Birds are not Peacock.

Conclusion I ("All Birds are Peacock") directly contradicts the statement and is false. Conclusion II ("Some Birds are not Peacock") is a direct restatement of part of the premise, making it definitely true.

Explanation

The statements give: No Houses are White, Only a few Brown are Houses, and Some Bricks are Brown.

Conclusion I ("All Brown can be White") is false because the portion of Brown that are Houses can never be White due to the premise that No Houses are White. Conclusion II ("Some Bricks are Houses is a possibility") is valid because there is no negative constraint between Bricks and Houses.

Explanation

From "Only a few Bold is Italic", some Bold are Italic. Since "Each Italic is Underline", those Bold that are Italic must also be Underline, making "Some Bold are Underline" a definite certainty. In formal logic, asserting a definite fact as merely a possibility makes the conclusion invalid.

For Conclusion II, no negative relationship is given between Straight and Italic, so "No Straight are Italic" cannot be derived definitely. Hence, neither conclusion follows.

Explanation

Applying the transformation rules to the letters of "CHAMPION": Consonants (-1): C becomes B, H becomes G, M becomes L, P becomes O, N becomes M. Vowels (+1): A becomes B, I becomes J, O becomes P.

The transformed arrangement is B, G, B, L, O, J, P, M. Checking each letter against the vowels (A, E, I, O, U), only O is a vowel, so there is exactly one vowel in the new arrangement.

Explanation

Determining the seating positions from left to right gives: Position 1: Z Position 2: E Position 3: G Position 4: R Position 5: Empty Position 6: U Position 7: Empty Position 8: Y Position 9: Empty Position 10: Empty Position 11: M Position 12: Empty

Since M is at position 11 and U is at position 6, counting five places to the left from M reaches U.

Explanation

Placing R fourth from the left end at position 4 and second to the right of E puts E at position 2. Five persons between E and Y places Y at position 8. Z sits seventh to the left of Y at position 1, establishing the left end. M sits two places to the right of Y at position 11. Since M is second from an end, the right end of the row is position 12, giving a total of 12 persons in the row.

Explanation

U is situated at position 6. Moving 5 positions to the left leads to position 1, which is occupied by Z. Moving 2 positions to the right from Z leads to position 3, which is occupied by G.

Explanation

In the series F 5 * E 2 D U # Z R S 8 9 @ J M 1 L O 3 X 7 % Q, the 12th element from the left end is the letter S. The letters appearing to the right of S in sequence are: 1st letter to the right: J 2nd letter to the right: M 3rd letter to the right: L

Explanation

The second number from the left end is 2 (at index 6). The third number from the right end is 1 (at index 19). The elements present between index 6 and index 19 are D, U, #, Z, R, S, | , 8, 9, @, J, M. The symbols within this segment are #, | , and @, totaling three symbols.

Explanation

Scanning the series for the Letter-Number-Symbol sequence: 5 is preceded by F and followed by (F 5 ) 1 is preceded by M and followed by (M 1) 7 is preceded by X and followed by % (X 7 %)

All three instances satisfy the given criteria.

Explanation

After dropping all symbols and consonants from the series, only the vowels and numbers remain: 5, E, 2, U, 8, 9, 1, O, 3, 7

Counting from the right end: 1st from right: 7 2nd from right: 3 3rd from right: O 4th from right: 1 5th from right: 9 6th from right: 8 7th from right: U

Explanation

The 4th letter from the right end of the series is L. The 6th letter from the left end of the series is R. In standard English alphabetical order, L is the 12th letter and R is the 18th letter. The letters falling strictly between them are M, N, O, P, and Q, making a total of five letters.

Explanation

Examining the number 27486935 digit by digit: For digit 2 at position 1 and digit 4 at position 3: distance is 2, with 1 digit between them. For digit 2 at position 1 and digit 6 at position 5: distance is 4, with 3 digits between them. For digit 4 at position 3 and digit 6 at position 5: distance is 2, with 1 digit between them.

No other digit pair in either direction satisfies this condition.

Explanation

Tracing the given relative positions: Distance from X to Y = 8m Distance from Y to Z = 4m Distance from Z to F = 7m

Summing these individual path segment distances yields 8 + 4 + 7 = 19m.

Explanation

Assign Cartesian coordinates by placing Point Y at the origin (0, 0).

Point Z is 4m east of Y, so Z = (4, 0). Point F is 7m south of Z, so F = (4, -7). Point A is 5m east of F, so A = (9, -7). Point B is 6m north of A, so B = (9, -1). Point G is 9m west of B, so G = (0, -1). Point E is 8m south of G, so E = (0, -9).

The shortest distance between Point E (0, -9) and Point F (4, -7) is calculated using the distance formula: Distance = √((4 - 0)² + (-7 - (-9))²) = √(4² + 2²) = √(16 + 4) = √20 m.

Explanation

Taking Point Y as the reference origin (0, 0), the coordinates of all points are determined as follows: Point Y = (0, 0) Point X = (0, 8) Point Z = (4, 0) Point F = (4, -7) Point A = (9, -7) Point B = (9, -1) Point G = (0, -1) Point E = (0, -9)

Relative to Point B at (9, -1), Point Y at (0, 0) has an x-offset of -9 meters (West) and a y-offset of +1 meter (North). Therefore, Point Y is to the North-West of Point B.

Explanation

Evaluating all conditions gives the exact month order for the seven persons: January (31 days): N March (31 days): I April (30 days): H July (31 days): K September (30 days): J October (31 days): M November (30 days): L

M appeared in October, which is the sixth month in the arrangement. Thus, exactly one person (L in November) appeared after M.

Explanation

Evaluating the given constraints determines the unique monthly schedule: January: N March: I April: H July: K September: J October: M November: L

Therefore, J appeared in September.

Explanation

The complete arrangement of persons by month is: January (Month 1): N March (Month 2): I April (Month 3): H July (Month 4): K September (Month 5): J October (Month 6): M November (Month 7): L

I appeared in March and L appeared in November, so I appeared before L, making statement II true. N appeared in January, which is month 1 (an odd-numbered month), so statement I is false. Three persons appeared before K, which is an odd number, so statement III is false.

Explanation

Determining the sequence from the given rules gives: January: N March: I April: H July: K September: J October: M November: L

Thus, M appeared in October.

Explanation

The monthly sequence of appearances is: January: N March: I April: H July: K September: J October: M November: L

I appeared in March and K appeared in July. Exactly one person, H (in April), appeared between them.

Explanation

The first word from the right end is BAT, whose first letter is B. The first word from the left end is TAN, whose last letter is N.

Alphabetical positions: B = 2 N = 14

The number of letters strictly between B and N is 14 - 2 - 1 = 11 (C, D, E, F, G, H, I, J, K, L, M).

Explanation

Advancing vowels by one position yields consonants. Retracting consonants by one position produces a vowel only if the consonant is B, F, J, P, or V (converting to A, E, I, O, U).

Transforming each word: TAN becomes SBM DCE becomes CBF LOG becomes KPF SPY becomes ROX BAT becomes ABS

Only ROX and ABS contain at least one vowel, making two words in total.

Explanation

Arranging the letters of each word in reverse alphabetical order from left to right yields: TAN → TNA DCE → EDC LOG → OLG SPY → YSP BAT → TBA

None of these combinations forms a meaningful English word, so zero meaningful words are created.
