Data Sufficiency Quiz | Reasoning MCQ Practice for IBPS AFO 2026

Passage

Directions: Each question is followed by two statements. Determine whether the statements are sufficient to answer the question. Mark: (A) Statement I alone is sufficient. (B) Statement II alone is sufficient. (C) Either I or II alone is sufficient. (D) Both I and II together are sufficient. (E) Neither I nor II together are sufficient.

1

Towards which direction is Point Y from Point X? I. Point Y is to the north of Point Z, which is to the east of Point X. II. Point Y is 5 m away from Point X.

Solution & Explanation Statement I alone establishes that X is east of Z, and Y is north of Z, making Y north-east of X. Statement II alone gives only distance, not direction. Hence, only Statement I alone is sufficient.

Passage

Direction: Below is a question and three statements numbered I, II and III. Decide which statement(s) is/are necessary and sufficient to answer the question, and choose your answer from the options below.
I. P is the son of Q.
II. Q is the brother of R's father.
III. R has one younger brother.

2

How is P related to R?

Solution & Explanation Statement I tells us P is Q's son. Statement II tells us Q is the brother of R's father, making Q R's paternal uncle. Combining I and II: P, the son of R's paternal uncle, is R's cousin — a complete and unambiguous answer. Statement III, about R having a younger brother, has no bearing on how P is related to R and is not needed. Neither I nor II alone mentions both P and R together, so neither is individually sufficient — only I and II together answer the question.

Passage

Direction: A question and two statements numbered I and II are given below it. Decide whether the data provided in the statements are sufficient to answer the question.
A six storey building consists of an unoccupied ground floor; the floor above the ground floor is floor no. 1, and so on, with the topmost floor being no. 5. Different people live in the building, viz. I, J, K, L and M.
I. K lives on an even numbered floor. I lives immediately above L. J lives immediately above I. M does not live on the topmost floor.
II. L lives on an odd numbered floor. I and J are immediate neighbours of each other. Similarly, K and M are immediate neighbours of each other. K does not live on an odd numbered floor.

3

Who lives on the third floor?

The data in either Statement I alone or Statement II alone is sufficient to answer the question.

The data in both Statements I and II together are not sufficient to answer the question.

The data in Statement I alone is sufficient to answer the question, while the data in Statement II alone is not sufficient.

The data in both Statements I and II together are necessary to answer the question.

The data in Statement II alone is sufficient to answer the question, while the data in Statement I alone is not sufficient.

Solution & Explanation Statement I gives the unique arrangement K(2), L(3), I(4), J(5), M(1). Hence L lives on floor 3. Statement II alone permits multiple arrangements and is insufficient. Therefore, option A is correct.

Passage

Directions: Each question is followed by two statements. Determine whether the statements are sufficient to answer the question. Mark: (A) Statement I alone is sufficient. (B) Statement II alone is sufficient. (C) Either I or II alone is sufficient. (D) Both I and II together are sufficient. (E) Neither I nor II together are sufficient.

4

Among A, B, C, D and E, who is the tallest? I. A is taller than B and C. II. D is taller than A but shorter than E.

Solution & Explanation Statement I alone gives A > B and A > C, but does not rank D and E. Statement II alone gives E > D > A, but does not rank B and C. Combining both, E > D > A > B and A > C, so E is the tallest. Both statements together are required.

4 / 5

Passage-based question

5

How is P related to R? I. P is the son of Q. II. Q is the sister of R.

Solution & Explanation Statement I alone gives no relation between P and R. Statement II alone gives no relation between P and R. Combining both, P is the son of Q, and Q is the sister of R. Therefore, P is the male child of R's sibling, i.e., P is the nephew of R. Both statements together are sufficient.
