Question

Six people - P, Q, R, S, T and U - sit around a circular table, not necessarily in the same order. Q and T sit opposite to each other. Does R sit opposite to S?
I. If R and T interchange their positions, then T will be to the immediate left of Q.
II. If P and Q interchange their positions, then Q will be to the immediate left of T.

• A. If the question can be answered by any one of the statements alone, but cannot be answered by using the other statement alone.
• B. If the question can be answered by using either statement alone.
• C. If the question can be answered by using both the statements together, but cannot be answered by using either statement alone.
• D. If the question cannot be answered even by using both the statements together.

Answer 1

The correct option is C

If the question can be answered by using both the statements together, but cannot be answered by using either statement alone.

Given that Q and T sit opposite to each other.
As per statement (I) alone, we get that R is to the immediate left of Q.

Hence, from statement (I) alone, we cannot say whether R sits opposite to S or not.
From statement (II) alone, we get P is to the immediate left of T.

So, statement (II) alone is not sufficient. Combining statement (I) and (II) we get.

P and R are opposite to each other. So, we can determine that R does not sit opposite to S.
Hence, both statements are required.
