In a family having two generations, there are 7 members, P, Q, R, S, T, U, and V. There are two married couples in the family. There are four females in the family. T and V are married but not to each other. U is the nephew of S. P and Q are siblings of the same gender. T and S are brothers. R is the mother in law of V. How is P related to V?
Correct Answer : b ) Sister in lawExplanation :
Let us assume m corresponds to male, f corresponds to female, horizontal lines denote relationship of brother or sister, vertical/inclined lines denote father/mother with son/daughter relationship and double horizontal lines will denote husband wife relationship.
Let us draw the family tree step wise step using the information given above
Information: There are four females in the family. T and S are brothers. U is the nephew of S.
From the above information, we can say that
T, S, and U are males in the family and P, Q, R and V are the females in the family.
Information: T and V are married but not to each other. R is the mother in law of V.
From the above information, we can say that as T and V are married and R is mother-in-law of V so we can conclude that T will be married to R and V is the wife of R’s son.
Information: P and Q are siblings of the same gender. T and S are brothers.
As, T and S are in the first generation so the only male left for the position of V’s husband will be U.
And, P and Q cannot be children of U and V because there are only two generations in the family.
Thus, the family tree can be depicted as,
From the above figure, we can say that P is the sister in law of V.
Hence, (b) is the correct answer.
