CMAT 2023 · Logical Reasoning · Medium · Blood Relations

A is the son of B, whose mother is C. D is the husband of E the grand-daughter of C. If F is the wife of A, how is F's father-in-law related to D's daughter?

  1. A.

    Brother

  2. B.

    Uncle

  3. C.

    Grand father

  4. D.

    Cousin

Answer

C

Explanation

C is grandmother of A and E. F is married to A, so F's father-in-law is A's father B. Since E is grand-daughter of C, E is A's sibling. D is husband of E, so D's daughter is E's daughter. B is E's father, which makes B the grandfather of D's daughter.
