Both D and F are lighter than B.**(iii)** B is mother of D and lighter than E.**(iv)** C, a lady, is neither heaviest nor the lightest in the family.**(v)** E is lighter than C.**(vi)** The grandfather in the family is the heaviest.

**How many male members are there in the family ?**

** Option:**

**A.**Two

**B.**Three

**C.**Four

**D.**Data inadequate

**E.**None of these

**Answer: D . Data inadequate**

** Justification:**

In terms of weight, F < B, D < B, B < E, E < C. So, we have : D < F < B < E < C or F < D < B < E < C. C is not the heaviest. So, A is the heaviest. Thus, the sequence becomes : F < D < B < E < C < A or D < F < B < E < C < A.

D is the brother of F.

B is the mother of D and F.

A, being the heaviest, is the grandfather.

Now, C is a lady and so one couple is AC.

B is a female and so on cannot pair up with C. So, the other couples is BE.

**The sex of F is known.**
