There is a family of five members, K, L, M, N and O. Among them, there is a married couple. L is unmarried and is the brother of K. N is sister of O. M is the only married woman and mother of N. There are only two men in group L and O. Who is the father of K? MCQ with Answer and Explanation

Explanation:
L & M → L wife of M. M # N → M brother of N. N @ A → N daughter of A. A & B → A wife of B. So A and B are parents of N. M being brother of N is their son. Thus L is daughter-in-law of A and B. B # C → B brother of C, so C is sibling of B. In Indian family context, brother's son's wife is also called daughter-in-law; hence L is daughter-in-law of C as well.

Explanation:
R is the grandparent of Q. Since U is T's mother and T is brother of P's husband, R is intended to be T's father.

Explanation:
U is daughter of S, but likely the question intended 'How is U related to R?' U is daughter of S, S is father of R, so U is sister of R. Hence answer is Sister.
