(i) A, B, C, D, E and F are six members in a family in which there are two married couples.
(ii) D is brother of F. 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. Who among the following will be in the second place if all the members in the family are arranged in the descending order of their weights ?

A. A

B. C

C. D

D. Data inadequate

E. None of these

Answer: B. C

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 descending order of weights is :
A > C > E > B > F > D or A > C > E > B > D > F.
Clearly, C comes second.
