Practice Test: Blood Relations - 1 - CAT MCQ

• M is the father of O and O is the sister of P.
  This implies M is also the father of P.

• Since M is the father of both O and P, and P is the son of N,
  it means N is M's wife (because M and N are the parents of O and P).

• Q is the brother of M.

• Since N is the wife of M and Q is M’s brother, N is the sister-in-law of Q.

B is the brother of C, and D is the daughter of C, making B the uncle of D.
Therefore, the correct answer is that B is the uncle of D.

S is the daughter of Y, and Y is the daughter of M. Therefore, S is the granddaughter of M. Since T is S's sister, T is also the granddaughter of M. Thus, M is either the grandfather or grandmother of T.
