P is the husband of Q. R is the grandchild of P. P has only one child, a son, who is married to a child of T. T has only two children, one son and one daughter. X is a grandchild of T. S is a brother-in-law of the son of T. U and V are the children of T. W is married to the son of T. X is the son of U’s brother. How is V related to S?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Brother-in-law
A man’s brother-in-law is his sister’s husband or his wife’s brother, and the relation works both ways. First find which child of T is the son.
T’s only two children are U and V, one son and one daughter
U has a brother (X is the son of U’s brother), so V is T’s son and U is T’s daughter
W is married to the son of T, so W is V’s wife, and X is the son of V and W
P’s only son is married to a child of T, so he is married to T’s daughter U
S is a brother-in-law of V: the husband of V’s sister U (P’s son), a brother of V’s wife W or the husband of W’s sister
In every case V and S are brothers-in-law of each other, so V is S’s brother-in-law
