Which of the following is definitely a group of male members?
A.QU
B.QUT
C.QUP
D.UT
E.None of these

Answer 1

Hint: Here, we will find the two married couples. Then, we will find the relation of each family member with the other and their professions. Finally, we will find the group of male members in the family.

Complete step-by-step answer:
It is given to us that Q is the father of T, U is the grandfather of R, and S is the grandmother of T.
Since, S is the grandmother of T, she has to be the mother of Q.
It is also given that there are two married couples. One couple must be the grandmother of T and the grandfather of R, i.e., U is married to S. Since U and S are grandparents of R and T respectively, it is only possible that R and T are siblings.
There is one person remaining in the family, i.e., P. Since, there is another couple, it should be that of Q and P. This means that P is the wife of Q. And, R and T are their children.
Now, Q is a doctor, U is a contractor and S is a housewife. The remaining professions are that of a nurse and two students. Hence, P must be the nurse, and R and T must be the students.
Therefore, the male members of the family are only Q and U.
Thus, the correct option is A.

Note: To solve such problems, it is advisable, to begin with, a sentence that gives information about the parent-child relationship. The information given in such problems can also be used to draw a family tree. Here, we can make a mistake by considering T as a housewife and R as a contractor. Here two married couples implies that there are 2 men and 2 women in the family.
