Key Points

• Statement I alone: P has two sisters R and S — tells us about P's family but nothing about Q. Cannot determine Q's relation to P. Statement II alone: R's father is the brother of Q. R is P's sister. R's father = P's father.
• P's father is Q's brother means Q is P's aunt/uncle.
• But Q's gender unknown — could be aunt or uncle. Cannot fully determine.
• Both together: R's father = P's father (from I), who is Q's brother.
• So Q is P's father's sibling = P's uncle/aunt.
• Still gender of Q unknown. Cannot be determined.
• Answer: The Question cannot be answered even using any of the Statements.
