IBPS PO Prelims 2019 Reasoning Ability Questions with Solutions

Explanation

Solving the puzzle constraints yields the final schedule: Tuesday - P (Nepal), Wednesday - S (Bhutan), Thursday - Q (England), Friday - T (India), and Saturday - R (China). Thus, S belongs to Bhutan.

Explanation

Based on the schedule, T goes to watch the movie on Friday while Q goes on Thursday, making the statement that T goes on Thursday false.

Explanation

In the weekly sequence from Tuesday to Saturday (P on Tuesday, S on Wednesday, Q on Thursday, T on Friday, R on Saturday), four of the options consist of two entities separated by a single day. S (Wednesday) and R (Saturday) are separated by two days (Thursday and Friday), so this pair does not belong to the group.

Explanation

T belongs to India and watches the movie on Friday. The person who goes immediately after Friday is R, who watches the movie on Saturday.

Explanation

Following the schedule determined from the given conditions, P goes on Tuesday, S goes on Wednesday, Q goes on Thursday, T goes on Friday, and R goes on Saturday. Therefore, S goes to watch the movie on Wednesday.

Explanation

In sentence 1, "well deserving theory is" is coded as "hm no pq rs", and in sentence 2, "together they all deserving" is coded as "tu vw xy no". Comparing both statements, the word "deserving" is the only common word, and "no" is the only common code. Thus, the code for "deserving" is "no".

Explanation

From the statements: well=hm, deserving=no, theory=pq, is=rs, all=xy, other=hi, together=tu. 'well deserving candidate' = 'hm no jk' therefore candidate=jk. 'all candidate' = xy + jk = 'jk xy'.

Explanation

In sentence 1, "well deserving theory is" is coded as "hm no pq rs", where "deserving" is "no". In sentence 3, "all other theory well" is coded as "xy hi pq hm", where "all" is "xy" and "other" is "hi". In both statements, the remaining words are "theory" and "well", which correspond to the remaining codes "pq" and "hm". Since there is no further information to distinguish between "theory" and "well", the code for "theory" is either "pq" or "hm".

Explanation

In sentence 2, "together they all deserving" is coded as "tu vw xy no", and in sentence 4, "together with each other" is coded as "tu ab de hi". Comparing these two statements, "together" is the only common word and "tu" is the only common code. Therefore, the code for "together" is "tu".

Explanation

In sentence 2, "together they all deserving" is coded as "tu vw xy no", and in sentence 3, "all other theory well" is coded as "xy hi pq hm". The word "all" is common to both statements, and the code "xy" is the common code between them. Hence, the code for "all" is "xy".

Explanation

The statement "Only a few C is A" implies both "Some C is A" and "Some C is not A", which means C can never be completely included inside A; hence, Conclusion I does not follow. For Conclusion II, since there is no negative relationship established between B and D, it is possible for some B to be D, so Conclusion II follows.

Explanation

"Only a few A is B" directly means "Some A is B" and "Some A is not B", so Conclusion I definitely follows. Conclusion II states a possibility that all B can be inside A without violating the fact that some portion of A remains outside B, so Conclusion II also follows.

Explanation

"Only Mango is Fruit" translates to "All Fruit is Mango" with the added condition that Fruit cannot belong to or overlap with any other category except Mango. Consequently, Fruit cannot be Apple, nor can any Fruit be Banana, making both conclusions false.

Explanation

"Only a few Mango is Apple" means some Mango is not Apple, but all Apple can still lie inside Mango without violating this condition, making Conclusion I a valid possibility. Similarly, "Some Banana is Apple" does not restrict all Banana from being inside Apple, making Conclusion II also a valid possibility.

Explanation

From "Some City is District" and "All District is Village", it is a definite fact that "Some City is Village"; therefore, asking it as a possibility in Conclusion I is invalid and does not follow. The statement "Only a few Country is City" directly means both "Some Country is City" and "Some Country is not City", making Conclusion II definitely true.

Explanation

Positioning F at the 7th place from the left (3rd from the right end) forces D to be at position 4 facing South, which places B at position 1 (3rd to the right of D) and A at position 6 (2nd to the left of D). E is at position 3 facing North, making I sit at position 2 facing North and D at position 4 facing South, which satisfies the condition that E's neighbors face opposite directions. C is positioned 2nd to the right of F at position 9 facing North. Therefore, B and C occupy the extreme ends of the row.

Explanation

In the linear seating arrangement, from left to right, the positions are B (South), I (North), E (North), D (South), G (North), A (North), F (North), H (North), C (North). D is at position 4 facing South, so moving three positions to his left (towards the right end of the row) leads to F at position 7.

Explanation

In the linear arrangement, B and D face South while I, E, G, A, F, H, and C face North. In the pair I-D, I faces North and D faces South, while both individuals face North in each of the other four given pairs.

Explanation

In the linear arrangement, F occupies position 7 and H occupies position 8. Because they sit immediately adjacent to one another, zero persons are sitting between F and H.

Explanation

E is seated at position 3 from the left end of a 9-person row, which is an interior seat and not an extreme end.

Explanation

From the clues, more than three boxes are between yellow and orange, meaning there are 4 boxes between them, placing yellow and orange at the extreme ends. Since green is immediately above yellow, yellow cannot be at the top, so yellow is at position 1 (bottom), green is at position 2, and orange is at position 6 (top). Box A is placed at position 6 (orange). Therefore, the orange coloured box is kept at the top.

Explanation

Arranging the boxes from top (position 6) to bottom (position 1): position 6 is box A (orange), position 5 is box E (blue), position 4 is box C (black), position 3 is box B (white), position 2 is box F (green), and position 1 is box D (yellow). Since box E is at position 5, the four boxes C, B, F, and D are placed below box E, which is more than three.

Explanation

In the arrangement from top to bottom (A-Orange, E-Blue, C-Black, B-White, F-Green, D-Yellow), the colour of the box immediately below C is white, below B is green, below E is black, and below A is blue. However, the box immediately below F is yellow, not black (black is two positions above F). Thus, F-Black does not belong to the group.

Explanation

Box B is placed at position 3, box F (green) is at position 2, and box D (yellow) is at position 1. Therefore, the green coloured box (box F) is immediately below box B, making the statement that yellow coloured box is placed immediately below box B incorrect.

Explanation

From the family tree, G and A are siblings, and S is the father of G, which means S is also the father of A. A is female because she is the sister-in-law of F. If S is married to Y, Y is the mother of A, making A the daughter of Y.

Explanation

Analyzing the family tree: S is the father of G (male), H is the grandfather of X (male), G is the brother of A (male), and T is the grandson of S (male). The female members are A (unmarried sister), F (wife of G), and X (daughter of G). Thus, there are 4 male members in the family.

Explanation

G and A are brother and sister. X is the daughter of G and F. Therefore, X is the brother's daughter (niece) of A.

Explanation

Arranging the eight persons around the square table starting from corner position 1 clockwise: position 1 is O (corner, inside), position 2 is R (middle, outside), position 3 is T (corner, inside), position 4 is Q (middle, outside), position 5 is S (corner, inside), position 6 is P (middle, outside), position 7 is W (corner, inside), and position 8 is V (middle, outside). W is at position 7 facing center, so left is clockwise: 1st left is V (8), 2nd left is O (1), and 3rd left is R (2).

Explanation

W is at corner position 7 facing towards the center, so counting from the right of W goes counter-clockwise through positions 6 (P), 5 (S), 4 (Q), and 3 (T) before reaching R at position 2. This gives a total of 4 persons (P, S, Q, T) between R and W, which is more than three.

Explanation

In the square table arrangement, persons at the corners face inside towards the center, while persons at the middle sides face outside away from the center. O sits at a corner facing inside, while R, P, Q, and V all sit at the middle of the sides facing outside. Thus, O is the odd one out.

Explanation

Four corner seats face inward while four middle-side seats face outward. Placing O at the bottom-left corner facing center and S at the top-right corner facing center satisfies the condition that S faces O. R and V are adjacent to O on the left side and bottom side respectively. Since V faces south, P sits second to its left on the right side, Q sits opposite V on the top side, W sits at the bottom-right corner to make S second to its right, and T occupies the top-left corner. From R's position on the left side facing west, counting clockwise (to R's right) places T first, Q second, and S third.

Explanation

Since all Pencil is Colour and no Colour is Eraser, the portion of Pen that is Pencil can never be Eraser, making Conclusion I definitely true. Since the statement already asserts as a fact that all Pencil is Colour, stating it as a possibility in Conclusion II makes the conclusion invalid.

Explanation

The phrase 'Only a few Guava is Grapes' logically implies both 'Some Guava is Grapes' and 'Some Guava is not Grapes'. Thus, Conclusion II is a direct logical deduction. Conclusion I is not definite because no relationship between Mango and Guava is established.

Explanation

The universal negative statement 'No Europe is Africa' directly implies its particular negative 'Some Europe is not Africa', making Conclusion I true. Furthermore, because Some Asia is Europe and no Europe is Africa, the overlapping portion of Asia and Europe can never be Africa, making Conclusion II definitely true.

Explanation

Grey is a subset of White, which partially intersects Blue, while Blue is disjoint from Pink. Since Grey may or may not overlap Pink, neither 'Some Grey is not Pink' nor 'All Grey is Pink' can be asserted with certainty. Being mutually exclusive and exhaustive complementary statements, either Conclusion I or Conclusion II must hold.

Explanation

Since Some Sand is Land and No Water is Sand, the common part between Sand and Land can never be Water, making it impossible for all Land to be Water. Similarly, since Some Sky is not Water is a definite given fact, it is impossible for all Sky to be Water.

Explanation

From the statements, B ≤ A and A < J ≤ K. Combining these gives the direct relationship B < K. Since B is strictly less than K, neither B > K nor B = K can be true.

Explanation

Combining M ≥ L = P ≥ Q gives M ≥ Q, making Conclusion I definitely true. Combining S = R ≥ Q ≥ T > U gives S > U (or U < S), making Conclusion II definitely true.

Explanation

From G > H ≥ D = F > M, we get H > M, which refutes H ≤ M. Connecting G and N yields G > H ≥ D = F < N, where the presence of opposing inequality symbols (> and <) leaves the relation between G and N indeterminate.

Explanation

Arranging the fourteen persons in two rows of seven, Row 1 (facing south, positions 1 to 7 from west to east) contains A, C, E, F, D, B, G at positions 1 through 7 respectively. Row 2 (facing north, positions 1 to 7 from west to east) contains Q, S, P, U, R, V, T at positions 1 through 7 respectively. D is at position 5 facing south, so moving two places to D's right (towards position 1) leads to E at position 3. The person sitting opposite E in Row 2 is P at position 3.

Explanation

Arranging Row 1 (South-facing: A, C, E, F, D, B, G at positions 1 to 7) and Row 2 (North-facing: Q, S, P, U, R, V, T at positions 1 to 7), P is at position 3 and T is at position 7 in Row 2. The persons sitting between P and T are U, R, and V, which gives 3 persons.

Explanation

In the given arrangement, the pairs A-S, E-U, B-T, and C-P consist of a person in Row 1 at position x and a person in Row 2 at position x + 1. In contrast, F is at position 4 in Row 1 while V is at position 6 in Row 2, so the pair F-V does not follow this relative positional pattern.

Explanation

In the evaluated arrangement, D is positioned at seat 5 of Row 1 facing South and R is positioned at seat 5 of Row 2 facing North. Therefore, R directly faces D.

Explanation

In Row 1, G is seated at position 7 and faces South. For a person facing South, right corresponds to positions 1 through 6. Thus, all 6 persons (A, C, E, F, D, B) sit to the right of G.

Explanation

Analyzing the alphabetical positions, ZUSX, JECH, MHFK, and WRPU follow a pattern where the positional differences between consecutive letters are -5, -2, and +5. In QLGK, the positional differences are -5, -5, and +4, which breaks the pattern.

Explanation

Comparing statement 1 ("industry is not growing" → "rv ct jl gb") and statement 4 ("growing is well start" → "pk ct jl st"), "is" corresponds to "ct", leaving "jl" as the unique common code for "growing".

Explanation

Comparing the statements, "is" = "ct", "industry" = "rv", and "growing" = "jl", which leaves "not" = "gb". Comparing statements 2 and 3 gives "good" = "mn". Combining these gives "gb mn" as the code for "not good".

Explanation

Comparing statements 3 and 4, the common words are "start" and "well", and the common codes are "pk" and "st". Since there is no further information to distinguish between them, the code for "start" can be either "pk" or "st".

Explanation

Given "cook good well" is "pk kt mn", and knowing "good" = "mn", the code for "well" must be "pk" (as "pk" is shared with "start/well"), which leaves "cook" = "kt". Since "well" = "pk", "start" must be "st". Thus, the code for "cook start" is "st kt".

Explanation

From comparing statements 1, 2, and 3, "is" is coded as "ct" and "industry" is coded as "rv". Therefore, the code for "is industry" is "ct rv".
