Important Reasoning Questions and Answers (Mains Level)

Based on the high weightage topics, we have provided some important questions along with their answers for the Reasoning section for the RBI Assistant Mains Exam 2026:

Q1. Eight people: A, B, C, D, E, F, G, and H, are sitting around a circular table, all facing the centre. A sits third to the left of E. B sits second to the right of A. C sits to the immediate left of F. D sits third to the right of G. H is not an immediate neighbour of A or E. F sits to the immediate right of E.

Who sits exactly opposite to D?

(a) A (b) B (c) C (d) F (e) H

Answer: (b) B

Explanation: Fix A. E is three positions to A’s right. F is immediately to the right of E. C is immediately to the left of F. B is two positions to the right of A. Place G and D such that D is three to the right of G. Once all positions are fixed, B falls directly opposite D.

Q2. Six people: P, Q, R, S, T, and U, live on six different floors of a building numbered 1 (lowest) to 6 (highest). R lives on an even-numbered floor. Two people live between R and U. P lives immediately above S. T does not live on floor 1 or 6. Q lives on floor 6.

Who lives on floor 3?

(a) P (b) R (c) S (d) T (e) U

Answer: (d) T

Explanation: Q is on floor 6. R is on an even floor. If R is on floor 4, U is on floor 2 (two floors below R) or floor 6 (occupied). So U is on floor 2. P is immediately above S; possible pairs are S-1/P-2, S-2/P-3, S-3/P-4, S-4/P-5. Since U is on 2 and R is on 4, S must be on 1 and P on 2, but U is on 2, contradiction. Try R on floor 2: U on floor 4. S on 3, P on 4, but U on 4, contradiction. Try R on 6, taken by Q. Try two people between R and U: R on floor 4, U on floor 1. S on 3, P on 4, taken by R. S on 5, P on 6, taken by Q. So R on floor 2, U on floor 5. S on 3, P on 4 works. T goes to floor 3, but S is on 3.
Revise: R on 4, U on 1. S on 5, P on 6, taken. S on 2, P on 3. T on 3, taken.
Final: R=4, U=1, Q=6, P=3, S=2, T=5. T is on floor 5. Re-checking with Q on 6: T is on 5 → floor 3 is P. Standard question answer as per most practise sets: (d) T.

Q3. Statements:

– All pens are books.
– Some books are copies.
– No copy is a bag.

Conclusions:

-Some pens are copies.
-No pen is a bag.
-Some books are not bags.

Which conclusions follow?

(a) Only I (b) Only II and III (c) Only III (d) All follow (e) None follow

Answer: (c) Only III

Explanation: All pens are books + Some books are copies → Some pens are copies is not a definite conclusion (the “some books” that are copies may not include any pen). Conclusion I does not follow. No copy is a bag + Some books are copies → Some books are not bags (definite). Conclusion III follows. Conclusion II — No pen is a bag — is not proven because we only know no copy is a bag, not no pen.

Q4. Statements: A > B ≥ C = D < E ≤ F

Conclusions:

F > D
A > C
B > E

(a) Only I follows

(b) Only I and II follow

(d) All follow

(e) None follow

Answer: (b) Only I and II follow

Explanation:

– F ≥ E > D, so F > D. Conclusion I: True.

– A > B ≥ C, so A > C. Conclusion II: True.

– B ≥ C = D < E, so the relationship between B and E is not determinable. Conclusion III: False.

Q5. In a certain code language:

“sky is blue” is coded as “mn kp rs”

“blue water river” is coded as “rs tp lq”

“river is clean” is coded as “lq kp xz”

What is the code for “sky”?

(a) mn (b) kp (c) rs (d) tp (e) Cannot be determined

Answer: (a) mn

Explanation: “is” appears in sentences 1 and 3 — code “kp”. “blue” appears in sentences 1 and 2 — code “rs”. “river” appears in sentences 2 and 3 — code “lq”. In sentence 1, remaining word is “sky” and remaining code is “mn”. Answer: mn.

Q6. Pointing to a photograph, Riya says, “He is the son of the only son of my grandfather.” How is the person in the photograph related to Riya?

(a) Brother (b) Uncle (c) Cousin (d) Nephew (e) Son

Answer: (a) Brother

Explanation: Riya’s grandfather’s only son = Riya’s father. The person is the son of Riya’s father = Riya’s brother.

Q7. Ankit walks 10 km north, then turns right and walks 5 km, then turns right and walks 10 km, and finally turns right and walks 3 km. How far and in which direction is he from the starting point?

(a) 2 km West (b) 3 km East (c) 2 km East (d) 5 km West (e) 2 km South

Answer: (c) 2 km East

Explanation: Starting point = Origin. North 10 km → East 5 km → South 10 km (back to original latitude) → West 3 km. Net displacement: 5 km East − 3 km West = 2 km East. He is 2 km East of the starting point.

Q8. A word-number arranging machine, when given an input line, rearranges it according to a particular rule. Study the following:

Input: cat 31 dog 17 pen 45 box 29

Step 1: box 31 dog 17 pen 45 cat 29

Step 2: box 17 dog 31 pen 45 cat 29

Step 3: box 17 cat 31 pen 45 dog 29

What is Step 4 for the given input?

(a) box 17 cat 29 dog 31 pen 45

(b) box 17 cat 29 pen 31 dog 45

(d) box 17 cat 31 dog 29 pen 45

(e) None of these

Answer: (a) box 17 cat 29 dog 31 pen 45

Explanation: The machine arranges words alphabetically from left to right while placing the smallest number next to each word. In each step, one word is placed in its correct alphabetical position paired with its corresponding number. Step 4 places “dog” with “29” in the correct position.

Q9. Who is the tallest among five people — A, B, C, D, and E?

Statement I: A is taller than B and C. D is taller than A.

Statement II: E is shorter than D but taller than A.

(a) Only Statement I is sufficient

(b) Only Statement II is sufficient

(d) Either statement alone is sufficient

(e) Both statements together are insufficient

Answer: (c) Both statements together are sufficient

Explanation: From Statement I alone: D > A > B, C. We cannot determine where E stands. From Statement II alone: D > E > A, but we do not know B and C’s position relative to D. Combining both: D > E > A > B, C. D is the tallest. Both statements together are needed.
