In a family gathering, six people, P, Q, R, S, T, and U, are sitting around a table. There are two fathers, three brothers, and a mother in this group.
R is the sister of U. Q is the brother of T's husband. S is the father of P and the grandfather of U. Both S and P have two children.
Find the three brothers in the group.

The correct option is A P, Q, and U
Let us represent the females using (–) and the males using (+).

There are two fathers, three brothers, and a mother in the group.

• R is the sister of U.

• S is the father of P and the grandfather of U.

This means that S is the father of P, and P is the father of U.


Thus, the two fathers in the group are S and P. The two children of P are R and U. There are two children of S as well.

• Q is the brother of T's husband.

If T is the wife of P, then Q will be the brother of P. The two children of S will be P and Q.


So, the three brothers are P, Q, and U.
The two fathers are S and P, and T is the only mother in the group.
