Question

P and Q are brothers, X and Y are sisters, son of P is the brother of Y. How is Q relation to X?

Answer 1

Hint: We need to go step-by-step first determine who X is to P and Q is to P. And then, find the relation between X and Q.
Complete step-by-step answer:
1. P and Q are brothers
2. X and Y are sisters
3. P has a son
4. P’s son, X, Y are siblings.

In the diagram, we take square boxes as males and circle as females.
If P is the father and has three children.
Q is P’s brother.
So, Q is the uncle of P’s children.
So, Q is the uncle of X and therefore X is the niece of Q.
Note: To solve, these relationship questions should be solved using a diagram (as given in this solution).
Take different shapes for male, female, husband-wife, brother-sister etc in the diagram otherwise these results may confuse students.
