    A. Only (1) B. Only (2) C. Either (1) or (2) D. (1) and (2) both

M is the father of N and N is the son of V.
Hence, V is the mother of N.
From (1), P is the brother of V
Therefore, M is the brother-in-law of P because V is the wife of M.
From (2), the daughter of N, is the granddaughter of V. From this we do not get any relation of M to P.

5x = 1350
x = 270
Smaller number = 270.
