  • II. R, the sister-in-law of M, is the daughter-in-law of S, who has only two kids, M and N.
  • Solution : (a)  :

    From I, we conclude that P is the mother of M and N, while Q is the daughter-in-law of P and sister-in-law of N. Thus, Q is M's wife and hence, M is N's brother.

    From II, we conclude that  M and N are the children of S. Also, R is the daughter in law of S and sister in law of M. so, R is N's wife and thus, N is M's brother. Hence M is either brother or sister of N.
