S is the grandmother of T and is a housewife. There is one doctor, one nurse ,one contractor, one housewife and two students in the family.
Which of the following are two married couples ?

Options

A. US,QT
B. US,QP
C. TS,RU
D. US, RP

Answer

B

Explanation

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.
The two married couples are Q, P and U, S.
