Data sufficiency - relation of Q to P
Question
A question is given followed by two Statements I and II. Consider the Question and the Statements and mark the correct option. Question: How is Q related to P? Statement I: P has two sisters, R and S. Statement II: R's father is the brother of Q. Which one of the following is correct in respect of the above Question and the Statements?
Options
The Question can be answered by using one of the Statements alone, but cannot be answered using the other statement alone.
The Question can be answered by using either Statement alone.
The Question can be answered by using both the Statements together, but cannot be answered using either Statement alone.
The Question cannot be answered even using any of the Statements.
Explanation
Combine the information to build the family tree. From Statement I, P, R, and S are siblings. From Statement II, R's father is the brother of Q. Since P and R are siblings, R's father is also P's father. Therefore, Q is the sibling of P's father. This makes Q either the uncle or the aunt of P. However, because neither statement specifies the gender of Q, we cannot lock down a single definitive relationship (uncle vs. aunt). Therefore, the data remains insufficient.
Answer: (d).
