There are six persons A, B, C, D, E and F.
C is the sister of F. B is the brother of E's husband. D is the father of A and
grandfather of F. There are two fathers, three brothers and a mother in the
group. Who is E's husband?

Option (C)

D is father of A and grandfather of F. So, A is father of F. Thus, D and A are the two fathers. C is the sister of F. So, C is the daughter of A. Since there is only one mother, it is evident that E is the wife of A and hence the mother of C and C and F. So, B is brother of A. There are three brothers. So, F is the brother of C. Clearly, A is E's husband.

. (I). A, B, C, D, E and F are six members of a family.

(II). One couple has parents and their children in the family.

(III). A is the son of C and E is the daughter of A.

(IV). D is the daughter of F who is the mother of E.

What relationship do D and E bear to each other ?

Option (D)

E is the daughter of A and F is the mother of E. So, A is the father of E and hence the husband of F. Now, D is the daughter of F. So, D and E are the daughters of A and F.

Also, A is the son of C. Now, only B remains. Thus, B and C are the parents of A.

Clearly, D and E are sisters.

A family consists of six members P, Q, R, S, T and U. There are two married couples. Q is a doctor and the father of T. U is grandfather of R and is a contractor. S is grandmother of T and is a housewife. There is one doctor, one contractor, one nurse, one housewife and two students in the family. Who is the sister of T?

Q, the Doctor, is the father of T. S, the Housewife, is the grandmother of T and hence the mother of Q. Since there are only two married couples one being that of Q, the grandfather of R i.e., U must be married to S. Thus, R and T will be both children of Q and these must be the students. So, P, who remains, shall be the wife of Q and she alone can be the nurse. Thus, U must be the contractor.

Clearly, R and T are children of same parents. So, R will be the sister of T.

The average of 6 quantities is 4. The average of 3 them is 3. What is the average of the remaining three numbers?

The average of 6 quantities is 4.

Therefore ,the sum of the 6 quantities is 6 Ã— 4 = 24.

The average of three of these 3 quantities is 3.

Therefore, the sum of these three quantities = 3 Ã— 3 = 9

The sum of the remaining three quantities = 24 - 9 = 15 .

Average of these three quantities = 15 / 3 = 5.
