IBPS RRB Clerk Prelims 2022 Reasoning Questions with Solutions

Explanation

Arranging the six persons in descending order of their money based on the given conditions gives F > B > C > D > E > A. C is 3rd, E is 5th, D is 4th, B is 2nd, and F is 1st. Therefore, A occupies the 6th position and has the least amount of money.

Explanation

From the descending order F > B (500) > C > D (300) > E > A, the amount of money C possesses must be strictly greater than 300 rupees and strictly less than 500 rupees. Among the given options, 450 is the only value falling within the range between 300 and 500.

Explanation

Based on the conditions, C is 3rd and E is 5th. D is 4th since D is less than both B and F and not the least. Since B does not have the highest money, F must be 1st and B must be 2nd. Thus, B has the second highest amount of money with 500 rupees.

Explanation

Comparing the second statement "Ultra motion sensor review" (sa pq vx zh) with the other statements reveals that "motion" is coded as "pq", "ultra" is coded as "sa", and "review" is coded as "zh". Removing these three known codes leaves "vx", which corresponds to "sensor".

Explanation

From statement 3 "Third umpire review pending" coded as "yt rs ub zh", "review" is "zh" and "pending" is "ub". The remaining words "Third" and "umpire" correspond to the remaining codes "yt" and "rs", but there is insufficient information to uniquely determine which one is "rs".

Explanation

"Review" is uniquely coded as "zh", whereas "Third" can be coded as either "yt" or "rs". Therefore, the combination for "Third review" can be either "yt zh" or "rs zh".

Explanation

Statement 1 "Slow motion cricket camera" is coded as "wq dr eg pq". "Motion" is "pq" and "cricket" is "eg", leaving "slow" and "camera" as "wq" or "dr". If "slow network" contains "dr", then "slow" is coded as "dr", which leaves "camera" uniquely coded as "wq".

Explanation

Comparing statement 1 and statement 4 uniquely identifies "cricket" as "eg". Comparing statement 2 with the rest uniquely identifies "sensor" as "vx". Thus, the code for "Cricket sensor" is "eg vx".

Explanation

Positioning the persons from left to right yields: A at position 1, 2 empty spots, B at position 4, 4 empty spots, D at position 9, 2 empty spots, F at position 12, 1 empty spot, H at position 14, G at position 15, 2 empty spots, L at position 18, 2 empty spots, M at position 21, 1 empty spot, and N at position 23. Between D (position 9) and F (position 12), there are exactly two persons at positions 10 and 11.

Explanation

In the linear seating arrangement, L is placed at position 18 and N is placed at position 23. Counting five positions to the right from position 18 (19, 20, 21, 22, 23) leads directly to N.

Explanation

Placing D at position 0 gives G at position 6, B at position -5, F at position 3, H at position 5, L at position 9, M at position 12, N at position 14, and A at position -8. The total arrangement spans from position -8 to 16. Position -4 lies midway between A (-8) and D (0). Since B is at position -5, position -4 is one position to the right of B.

Explanation

Determining relative positions from D at index 0 yields B at -5, F at 3, H at 5, G at 6, L at 9, M at 12, and N at 14. With two persons between M and L, there are two persons between B and extreme end A, placing A at -8. The condition that left of B has one more person than right of N gives three persons to the left of B, which means two persons to the right of N at positions 15 and 16. Counting all positions from -8 to 16 yields 16 - (-8) + 1 = 25 persons.

Explanation

Rank from bottom = Total students - Rank from top + 1. Tina's rank from top = 21. Ram's rank from top = 21 + 9 = 30. Ram's rank from bottom = 50 - 30 + 1 = 21.

Explanation

After swapping consecutive pairs of digits in 5078612493: 1st and 2nd digits (5, 0) become 0, 5. 3rd and 4th digits (7, 8) become 8, 7. 5th and 6th digits (6, 1) become 1, 6. 7th and 8th digits (2, 4) become 4, 2. 9th and 10th digits (9, 3) become 3, 9. The reordered sequence is 0 5 8 7 1 6 4 2 3 9. The 7th digit from the right end corresponds to the 4th digit from the left end, which is 7.

Explanation

Starting at (0,0) facing South, turning right sets the direction to West for 20 m to (-20, 0). Turning right again changes direction to North for 10 m to (-20, 10). Turning left sets direction to West for 10 m to (-30, 10). A final right turn directs North for 20 m to (-30, 30). Relative to the origin (0,0), position (-30, 30) lies in the North-West direction.

Explanation

Row 1 facing south consists of Q at 1, P at 2, O at 3, N at 4, M at 5. Row 2 facing north consists of B at 1, K at 2, A at 3, C at 4, L at 5. B is at position 1 and C is at position 4. The persons sitting between C and B are at positions 2 and 3, making a total of two persons.

Explanation

Row 1 facing south consists of Q at 1, P at 2, O at 3, N at 4, M at 5. Row 2 facing north consists of B at 1, K at 2, A at 3, C at 4, L at 5. O occupies position 3 in the first row and directly faces A, who occupies position 3 in the second row.

Explanation

Row 1 facing south consists of Q at 1, P at 2, O at 3, N at 4, M at 5. Row 2 facing north consists of B at 1, K at 2, A at 3, C at 4, L at 5. L (position 5, Row 2), M (position 5, Row 1), Q (position 1, Row 1), and B (position 1, Row 2) all occupy extreme end positions of their respective rows. C occupies position 4 in Row 2, which is an interior seat.

Explanation

Row 1 facing south consists of Q at 1, P at 2, O at 3, N at 4, M at 5. Row 2 facing north consists of B at 1, K at 2, A at 3, C at 4, L at 5. C sits at position 4 in Row 2 facing north. The person sitting 2nd to the left of C is at position 2, which is K. The person facing K in Row 1 at position 2 is P.

Explanation

After interchanging adjacent pairs of digits in 8639726545: 1st and 2nd digits (8, 6) become 6, 8. 3rd and 4th digits (3, 9) become 9, 3. 5th and 6th digits (7, 2) become 2, 7. 7th and 8th digits (6, 5) become 5, 6. 9th and 10th digits (4, 5) become 5, 4. The modified number is 6 8 9 3 2 7 5 6 5 4. The 4th digit from the left is 3 and the 7th digit from the left is 5. Sum = 3 + 5 = 8.

Explanation

From the given statements, "Only a few Gain are Loss" means some Gain are Loss and some Gain are not Loss. "Only a few Loss are Profit" means some Loss are Profit and some Loss are not Profit. "All Profit are Sale" places the entire set of Profit inside Sale. Gain can overlap completely with Sale without violating any statements, so conclusion I does not logically follow. However, all Loss can be inside Sale while maintaining all given conditions, making conclusion II a valid possibility. Thus, only conclusion II follows.

Explanation

"Only Grapes are Mango" implies that all Mango are Grapes and Mango cannot belong to any other set. Since "Some Grapes are Banana" and "No Banana are Guava", the specific portion of Grapes that overlaps with Banana cannot be Guava. Therefore, conclusion I strictly follows. Conclusion II fails because not all Grapes are required to be Banana.

Explanation

"No Good is Honest" and "All Honest are Kind" mean that the Honest portion of Kind can never be Good, so some Kind are definitely not Good. Furthermore, "Only a few Noble are Good" means some Noble are Good, and since no Good is Honest, those Noble that are Good can never be Honest, meaning some Noble are definitely not Honest. Therefore, both conclusions I and II logically follow.

Explanation

"Only a few Yellow is Green" explicitly implies that some Yellow is definitely not Green, which makes it impossible for all Yellow to be Green. Additionally, "Some Green is Pink" and "No Pink is Purple" do not establish any definite relation between Green and Purple. Thus, neither conclusion I nor II follows.

Explanation

The given number is 4728468472. Writing the digits in ascending order from right to left is equivalent to writing them in descending order from left to right, which yields 8877644422. Comparing the original sequence and the rearranged sequence position by position from left to right: Position 1: 4 vs 8 Position 2: 7 vs 8 Position 3: 2 vs 7 Position 4: 8 vs 7 Position 5: 4 vs 6 Position 6: 6 vs 4 Position 7: 8 vs 4 Position 8: 4 vs 4 Position 9: 7 vs 2 Position 10: 2 vs 2 The digits at positions 8 and 10 remain unchanged, giving a total of two numerals.

Explanation

Arranging the six people according to the given conditions gives the complete schedule: 18th June: M 23rd June: P 18th August: N 23rd August: Q 18th October: X 23rd October: Z X marries on 18th October (a 31-day month on an even date), and Z marries on 23rd October in the same month. N is two slots away on 18th August with Q on 23rd August. M marries on 18th June, which is before P on 23rd June. Thus, M gets married on 18th June.

Explanation

Following the derived schedule: 18th June: M 23rd June: P 18th August: N 23rd August: Q 18th October: X 23rd October: Z The person getting married on 23rd August is Q.

Explanation

In the final arrangement: M gets married on 18th June (June has 30 days). N gets married on 18th August (August has 31 days). Q gets married on 23rd August (August has 31 days). X gets married on 18th October (October has 31 days). Z gets married on 23rd October (October has 31 days). Since M is the only person getting married in a 30-day month while the others are married in 31-day months, M does not belong to the group.

Explanation

From the final marriage schedule: 18th August: N 23rd August: Q 18th October: X 23rd October: Z Q and X occupy consecutive marriage dates without any individual scheduled between them. Therefore, zero people are getting married between X and Q.

Explanation

The marriage schedule for the six persons is: 18th June: M 23rd June: P 18th August: N 23rd August: Q 18th October: X 23rd October: Z Hence, X gets married on 18th October.

Explanation

Placing four corner seats facing inside and four middle side seats facing outside, F sits at the top-left corner facing inside, C sits at the bottom-left corner facing inside, G sits at the bottom-mid side facing outside, A sits opposite F at the bottom-right corner, B sits at the left-mid side facing outside, E sits at the top-right corner facing inside, H sits at the right-mid side facing outside, and D sits at the top-mid side facing outside. Since D faces outside, the direction to D's immediate right is clockwise, where E is seated.

Explanation

From the derived seating arrangement, H occupies the middle of the right side and B occupies the middle of the left side. Counting either clockwise through A, G, and C or counter-clockwise through E, D, and F, there are exactly three persons sitting between H and B.

Explanation

F sits at the top-left corner facing inside, so counting three positions clockwise gives H at the middle of the right side. Since H faces outside, counting two positions clockwise to the right of H leads to G at the middle of the bottom side.

Explanation

H is seated at the middle of the right side facing outside, so moving clockwise along H's right side brings C to the bottom-left corner as the third person to H's right, not to H's left.

Explanation

H is positioned at the right-mid side facing outside. The two adjacent corner seats directly next to H are occupied by E at the top-right corner and A at the bottom-right corner.

Explanation

Mapping the movements from A at (0, 0): B is at (10, 0), C is at (10, -5), D is at (20, -5), and E is at (20, 5). The point located 5m north of D has coordinates (20, -5 + 5) = (20, 0). Comparing A (0, 0) to this point (20, 0), A lies directly along the negative x-axis, which is West.

Explanation

Point A is located at (0, 0) and point E is at (20, 5). The shortest distance between them is given by the Pythagorean theorem: √(20² + 5²) = √(400 + 25) = √425 = 5√17 m.

Explanation

Point C is at coordinates (10, -5) and point E is at (20, 5). Moving from C to E requires traveling +10m in the x-direction (East) and +10m in the y-direction (North), making the direction of E with respect to C Northeast.

Explanation

Point E is at (20, 5), so Point X, located 10m west of E, has coordinates (10, 5). Since Point C is at (10, -5), both points share the same x-coordinate, and the shortest distance between them is the vertical difference |5 - (-5)| = 10m.

Explanation

Since all Pat are Hak and no Hak is Dak, the set of Pat is entirely disjoint from Dak, making Conclusion I true. Furthermore, the subset of Rat that overlaps with Pat consists of Haks, and since no Hak is Dak, those Rats cannot be Dak, making Conclusion II true.

Explanation

From the given statements, there is no direct or indirect relation linking 22 and 17, making both individual conclusions uncertain. Since conclusion I (No 22 is 17) and conclusion II (Some 17 is 22) form a complementary pair covering all possible relationships between 22 and 17, exactly one of them must be true.

Explanation

The given statements establish that no Blue is Pink, which means it is impossible for any Blue to be Pink. Furthermore, there is no statement guaranteeing that Black overlaps with Pink, so the assertion that some Black are Pink is not definitely true.

Explanation

Since all Lily are inside Sun and no Sun is Lotus, Lotus and Lily cannot share any elements, making No Lotus is Lily definitely true. On the other hand, All Rose are Lotus does not imply that all Lotus are Rose, so the first conclusion does not follow.

Explanation

Since all Ear are Nose and no Nose is Eye, Ear and Eye have no overlap, which contradicts the claim that all Eye are Ear. Additionally, no relationship is established between Eye and Hand, so it cannot be concluded that no Eye is Hand.

Explanation

Arranging the eight individuals around the circle facing outwards, the clockwise order of positions starting from L is L, B, K, G, D, M, H, and F. In an outward-facing circular layout, immediate right corresponds to the clockwise direction, which places L immediately to the right of F.

Explanation

In the circular arrangement, F is at position 8 and B is at position 2, leaving two positions between them, whereas in all other given pairs the two persons sit directly opposite each other with three persons between them.

Explanation

In the outward-facing circular arrangement, moving right from K corresponds to moving clockwise. The positions traversed between K and F in the clockwise direction are occupied by G, D, M, and H, giving a total count of four persons.

Explanation

In an outward-facing circular arrangement, counting left means moving counter-clockwise. Counting counter-clockwise from M to H passes through six individuals: D, G, K, B, L, and F. Similarly, counting counter-clockwise from L to B passes through six individuals: F, H, M, D, G, and K.

Explanation

With all persons facing outside the center, left corresponds to the counter-clockwise direction. Moving three steps counter-clockwise from B passes through L as the 1st, F as the 2nd, and arrives at H as the 3rd person to the left.

Explanation

Scanning the series for a number preceded by an alphabet and followed by a symbol yields only 1 in the sequence U 1 | , where U is an alphabet and | is a symbol.
