(i) A and D have to be together.

(ii) C cannot go with S.

(iii) S and T have to be together.

(iv) B cannot be teamed with E.

(v) D cannot go with P.

(vi) B and R have to be together.

(vii) C and Q have to be together.

How is A related to E ?

• A. Brother
• B. Uncle
• C. Father
• D. Grandfather
• E. None of these

Answer 1

The correct option is D Grandfather

Given F is a psychologist.

B is the mother of F and E is the brother or sister of F.

There are only two married couples in the family. Since, D is married to A, so C, the jeweller, who is married to a lawyer, will be married to B.

Again, the Manager D is married to A means A is the doctor and Grandfather of F and E.

Also, no one else is an Engineer. So, E must be an Engineer.

Clearly, A is the grandfather of F and E is the brother or sister of F.

So, A is the grandfather of E. Hence, the answer is (D).
