I. B is the father of M. M is the sister of T. T is the mother of F.

II. S is the son of F. V is the daughter of F. R is the brother of T.



A If data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.

B If data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question.

C If the data either in statement I alone or in statement II alone are sufficient to answer the question.

D If the data even in both statements I and II together are not sufficient to answer the question.

E If the data in both statements I and II together are necessary to answer the question.

Ans. D

Using statement I

The gender of F is not known. So, we cannot say F is granddaughter or grandson of B.

Using statement II

R+ T

The name of B has not even been mentioned.

Using both statements together

Still, the gender of F cannot be determined. So, we cannot determine if F is grandson or granddaughter of B.
