IBPS RRB Clerk Prelims 2022 Reasoning Questions with Solutions

Explanation

Comparing 'Fuel and Power Inflation' (lv cn ob tz) and 'Fuel Push and ever' (ob xa el cn), the common words are 'Fuel' and 'and', which correspond to codes 'cn' and 'ob'. Comparing 'Surging Price Fuel Push' (el or mb cn) shows that 'cn' represents 'Fuel'. Consequently, the code for 'and' is 'ob'.

Explanation

From the statements, 'Inflation' corresponds to 'tz' and 'ever' corresponds to 'xa'. Thus, 'record' must be coded as either 'yc' or 'vc'. Since 'fire' is a new word not present in any statement, its code must be a new code that has not appeared previously. The pair 'yu yc' satisfies these conditions by pairing the potential code 'yc' for 'record' with a completely new code 'yu'.

Explanation

Placing Q on 24th September positions T on 24th July, leaving six slots after T and requiring R on 17th October to have six slots before R. Position 24th August for S satisfies having more than one person between R and S, with S on an even date. Setting U on 17th July and V on 24th October balances the number of persons before U and after V. Placing P on 17th August and W on 17th September satisfies all remaining conditions. Thus, R attends the meeting on 17th October.

Explanation

According to the final schedule, P attends on 17th August and V attends on 24th October. The delegates who attend between them are S (24th August), W (17th September), Q (24th September), and R (17th October), making a total of four persons, which is more than three.

Explanation

In the evaluated arrangement, P attends the meeting on 17th August and S attends on 24th August. Since 24th August is the very next meeting date following 17th August, S attends immediately after P.

Explanation

R attends the meeting on 17th October, and the next meeting in sequence is on 24th October, which is attended by V.

Explanation

P attends the meeting on 17th August, which is an odd-numbered date, whereas all other delegates in the group attend on the 24th of their respective months, which are even-numbered dates.

Explanation

All Kiwi are inside Mango, and all Mango are inside Orange. The condition that only a few Orange are Papaya means Papaya overlaps with Orange without restricting Papaya from overlapping with Mango. Thus, it is possible for some Papaya to be Mango, making conclusion II logically valid, while conclusion I does not necessarily follow.

Explanation

The premise states that no Grey are Black and all Black are Blue, while only a few Pink are Grey. This leaves the portion of Pink that is not Grey free to overlap with Black. Therefore, it is possible for some Black to be Pink. Conclusion II does not necessarily follow as Blue is not required to be entirely within Pink.

Explanation

Since no Song is Bad and all Lyrics are Song, no Lyrics can be Bad, which directly implies that some Lyrics are not Bad. Furthermore, since all Lyrics are Song and no Lyrics is Sweet, the Songs that are Lyrics are not Sweet, meaning some Song are not Sweet.

Explanation

The statement "Only a few Book are Pencil" means some Books are Pencils and some Books are not Pencils, but it does not prevent all Pencils from being inside Books. Since all Pencils are Pens and some Pens are Students, there is no restriction preventing all Pens from being inside Books. Therefore, Conclusion I is a valid possibility. Similarly, there is no negative relation given between Student and Pencil, making Conclusion II a valid possibility as well. Thus, both conclusions follow.

Explanation

From the given statements, no direct relationship exists between Earth and Star, so "Some Earth are Star" cannot be definitely concluded. Additionally, "All Sun are Earth" indicates that Sun is a subset of Earth, which does not guarantee that all Earth are Sun. Therefore, neither conclusion logically follows.

Explanation

R and U form the first-generation couple, where R is male and U is female. T is the male child of R and U, and T is married to Q, with S being their child. Thus, U is the grandmother of S, and T is the son of S's grandmother U.

Explanation

R is the father of P and T. Since T is married to Q, Q is the wife of R's son. Therefore, Q is the daughter-in-law of P's father R.

Explanation

Q and T are the parents of S, who is female since the family contains only two males (R and T). If S marries V, V must be male, making V the son-in-law of Q.

Explanation

In the series E @ * 4 9 7 @ 4 H 5 V J N % M 2 # V 1 F, checking all letters shows that none are immediately preceded by a digit and immediately followed by a symbol. Thus, there are no such letters.

Explanation

Removing the symbols @, *, , %, #, and from the series yields the sequence E 4 9 7 4 H 5 V J N M 2 V 1 F. Counting from the right end gives F as 1st, 1 as 2nd, V as 3rd, 2 as 4th, and M as 5th.

Explanation

Scanning the series for the pattern Number-Symbol-Letter reveals two occurrences: 2 # V and 1 | F. Hence, there are two such symbols in the series.

Explanation

Counting from the left end, the 8th element in the series is 4. Counting from the right end, the 6th element is 2. The sum of these two elements is 4 + 2 = 6.

Explanation

The word MANIPULATE consists of the letters A, E, I, L, M, N, P, T, and U. The word Animated requires the letter D, which does not exist in MANIPULATE, making it impossible to form.

Explanation

From the given statement L = X ≥ A > Y < N ≤ O, combining the relations from L to Y gives L = X ≥ A > Y. Since L equals X, and X is greater than or equal to A, which is strictly greater than Y, it directly follows that L > Y, making conclusion II true. For conclusion I, comparing A and O gives A > Y < N ≤ O. Because opposite inequality signs (> and <) lie between A and O, no definite relationship can be established between them, so conclusion I does not follow. Thus, only conclusion II follows.

Explanation

From the statement E = H ≤ T > C > A ≤ B, the relation between H and C contains opposite inequality signs (H ≤ T and T > C), meaning no definite relation exists between H and C. Since E = H, conclusion I represents C < H and conclusion II represents C ≥ H. Combined together, C < H and C ≥ H cover all three possible real-number relationships between C and H (less than, equal to, or greater than). Therefore, either conclusion I or conclusion II must follow.

Explanation

From the statement R > G < T ≥ Q ≤ P, the path between R and Q contains opposite inequality signs (> and <), so no definite relationship can be derived between R and Q. For an either-or relation to hold when no relation can be established, the two conclusions must together cover all three basic relations: greater than, less than, and equal to. Conclusion I gives R > Q, while conclusion II gives Q ≤ R, which is equivalent to R ≥ Q (R > Q or R = Q). Since the less-than sign (R < Q) is not covered, an either-or pair is not formed. Thus, neither conclusion I nor II follows.

Explanation

From the statement M < R > A ≥ Z = P > S, tracing from R to S gives R > A ≥ Z = P > S. Since all inequality symbols along this path point in the same direction, R > S is definitively true, so conclusion I follows. Tracing from M to P gives M < R > A ≥ Z = P, which contains opposite inequality symbols (< and >), making it impossible to establish any definite relationship between M and P. Thus, conclusion II does not follow.

Explanation

The given number is 568941372, consisting of 9 digits in positions 1 through 9. Arranging these digits in descending order from left to right yields the sequence 987654321. Comparing the position of each digit in the original sequence with the new sequence: Position 1: 5 becomes 9 Position 2: 6 becomes 8 Position 3: 8 becomes 7 Position 4: 9 becomes 6 Position 5: 4 becomes 5 Position 6: 1 becomes 4 Position 7: 3 remains 3 Position 8: 7 becomes 2 Position 9: 2 becomes 1 Only the digit 3 remains in the same position (7th position) after arrangement.

Explanation

The eight persons sit in two parallel rows of four: Row 1 facing South and Row 2 facing North. F sitting 3rd to the left of E implies E and F sit at the extreme ends of Row 1. With Row 1 facing South, left corresponds to the East direction. Placing E at position 1 (West end) and F at position 4 (East end) gives the order of Row 1 from West to East as E, G, N, F. Row 2 from West to East is D, O, M, P facing North. In Row 1, counting two positions to the left (East) from E at position 1 leads to position 3, where N is seated.

Explanation

By analyzing all conditions, the row arrangements are uniquely determined as follows: Row 1 (facing South, West to East): E, G, N, F Row 2 (facing North, West to East): D, O, M, P Person D sits at position 1 of Row 2 facing North. Directly opposite D at position 1 of Row 1 sits E facing South. Therefore, E faces D.

Explanation

Based on the seating arrangement: Row 1 (facing South, West to East): E, G, N, F Row 2 (facing North, West to East): D, O, M, P The person facing D is E, located at position 1 in Row 1. Since the persons in Row 1 are facing South, immediate left corresponds to moving one position towards the East (position 2), which is occupied by G.

Explanation

The arrangement of persons in the two parallel rows is: Row 1 (facing South, West to East): E (position 1), G (position 2), N (position 3), F (position 4) Row 2 (facing North, West to East): D (position 1), O (position 2), M (position 3), P (position 4) The extreme ends of Row 1 are occupied by E and F, while the extreme ends of Row 2 are occupied by D and P. Thus, D is one of the persons sitting at an extreme end.

Explanation

The letters in the word SCHOOL are C, H, L, O, O, and S. Examining the choices, cohl, scol, losh, and sool are not standard English words. Therefore, no meaningful English word can be formed from the listed choices.

Explanation

Positions from left to right are numbered 1 to 19. X sits at position 2 (2nd from the left end), A sits at position 4, and E sits at position 5 (immediate right of A). M sits at position 13 (8 persons between A and M). S sits at position 15 (2nd right of M), and P sits at position 17 (2nd right of S). Q sits at position 9 (midpoint of E and M), and B sits at position 7 (1 person between B and E, matching 1 person between S and M, with B not adjacent to A or X). Since 3 persons sit to the left of A, there must be 2 persons to the right of P, placing P at position 17 and making the total number of persons 19.

Explanation

In the derived row arrangement, Q sits at position 9 and B sits at position 7. Counting 2 places to the left of position 9 gives position 7, where B is seated.

Explanation

B is seated at position 7 and P is seated at position 17. The number of persons sitting between position 7 and position 17 is calculated as 17 - 7 - 1 = 9.

Explanation

There are 2 persons to the right of P. One less than 2 is 1, and the person who has exactly 1 person to their left is X at position 2.

Explanation

Since Q is at position 9 and M is at position 13, D sitting midway between them is at position 11. Counting 4 positions to the right of position 11 gives position 15, where S is seated.

Explanation

Setting the starting house at coordinates (0, 0), walking 5 m South leads to (0, -5). Turning left and walking 6 m East leads to (6, -5). Turning left and walking 4 m North leads to (6, -1). Turning right and walking 3 m East leads to (9, -1). Finally, turning right and walking 2 m South reaches the office at (9, -3). Relative to the house at (0, 0), the direction of the office is South-East.

Explanation

The total distance covered is the sum of each individual leg of the walk: 5 m + 6 m + 4 m + 3 m + 2 m = 20 m.

Explanation

From the office at coordinates (9, -3), walking 3 m North places point A at (9, 0). Since the house is at (0, 0), it shares the same y-coordinate and has a smaller x-coordinate, placing the house directly West of point A.

Explanation

Arranging eight persons in clockwise positions 1 to 8 facing inward: E is at 1, A is at 2, G is at 3, D is at 4, B is at 5, F is at 6, C is at 7, and H is at 8. Facing the center from position 2 (A), 2nd to the right corresponds to position 8, where H sits.

Explanation

In the circular arrangement with all persons facing the center, H is at position 8 and B is at position 5. Moving counter-clockwise from position 8 to position 5 covers 3 places to the right.

Explanation

Placing the eight persons facing inside around the circle based on the given conditions gives the clockwise order: E, H, C, F, B, D, G, A. In this arrangement, E faces B, F faces A, and C faces G. No consecutive alphabetical persons sit adjacent to each other. Counting from the right of D (clockwise) to C, the persons sitting in between are G, A, E, and H, which equals four persons.

Explanation

Placing the eight persons facing inside around the circle based on the given conditions gives the clockwise order: E, H, C, F, B, D, G, A. C sits at position 3 and G sits at position 7, which are directly opposite each other across the table. Therefore, G faces C.

Explanation

Placing the eight persons facing inside around the circle based on the given conditions gives the clockwise order: E, H, C, F, B, D, G, A. Looking at the position of A, the person immediately to its left is G and immediately to its right is E. Thus, the immediate neighbours of A are G and E.

Explanation

The statement only a few A are D implies that some A are D and some A are not D. The statement some C are D indicates an overlap between C and D. Since no negative relationship exists between A and C, the possibility that some A can be C is true. Additionally, while all A cannot be D, all D can lie inside A without violating any given condition, making all D can be A a valid possibility. Therefore, both conclusions follow.

Explanation

Since all Play are inside Ground and no Ground can be Dry, it is impossible for any Play to be Dry, making conclusion I definitely true. For conclusion II, since some Play are Toy and all Play are Ground, that specific portion of Toy is Ground, but there is no rule preventing all Toy from being Ground, so conclusion II does not follow definitely. Therefore, only conclusion I follows.

Explanation

The statement only Bear is Teddy means that all Teddy are Bear and Teddy cannot share any relationship with any category other than Bear. Consequently, no Teddy can be Cat, making conclusion II definitely true. The statement no Lion is Bear creates a definite negative relation between Bear and Lion, which excludes any possibility of some Bear being Lion, making conclusion I false. Therefore, only conclusion II follows.

Explanation

The statement only a few 30 is 13 implies that a portion of 30 is inside 13. Since no 23 is 30, that portion of 13 which is 30 can never be 23, making some 13 is not 23 definitely true. Furthermore, no statement restricts 32 from being entirely included inside 13, so all 32 can be 13 is a valid possibility. Therefore, both conclusions follow.

Explanation

Combining the given inequality statements yields H > Y = J > E and K > Y = J > E. Comparing H and J, since H > Y and Y = J, substituting Y with J gives H > J, which makes conclusion I definitely true. Comparing E and K, the path gives K > E, which means E = K is false. Therefore, only conclusion I is true.

Explanation

From the statements I ≥ N = B = T and N < F = W, we can substitute equal terms. Since N = T, replacing N in I ≥ N gives I ≥ T, which is equivalent to T ≤ I, making conclusion I true. Since N = B and N < W, substituting B for N gives B < W, which is equivalent to W > B, making conclusion II true. Therefore, both conclusions are true.

Explanation

In the given inequality chain U > F < V > D < L = C > W, analyzing the relationship between V and C gives the path V > D < L = C. The presence of opposite inequality signs (> and <) means no definite relation can be established between V and C, so conclusion I does not follow. Similarly, for D and W, the path D < L = C > W contains opposite inequality signs (< and >), meaning no definite relation can be established, so conclusion II does not follow. Therefore, neither conclusion is true.
