Eight persons – P, Q, R, S, T, U, V and W – sit in a linear row. Some of them face North and some face South.

Note: Equal number of persons face north and south.

T sits third to the right of V. One person sits between S and V. Both S and V face opposite directions to each other. P sits immediately to the right of S. P and V are not immediate neighbours. Three persons sit between P and R. W sits second to the left of R. W is not an immediate neighbour of V. Immediate neighbours of R face in the direction opposite to each other. T sits immediate to the right of Q. The persons sit at both the ends of the row face opposite direction to each other. W and U face the same

If R is related to T and in the same way Q is related to U then S is related to who among the following persons?

The correct answer is V.

To determine who S is related to, we need to analyze the logical relationship defined between the given pairs of persons.

The question states:
"If R is related to T and in the same way Q is related to U then S is related to who among the following persons?"

Let's analyze the relationship pattern between the pairs:
1. R is related to T: This positional relationship means that there is exactly one person sitting between R and T (or T sits second to the left/right of R).
2. Q is related to U: Following the same pattern, there is exactly one person sitting between Q and U (or U sits second to the left/right of Q).
3. S is related to [?]: To find who S is related to, we look for the person who sits such that there is exactly one person between them and S.

From the clues provided in the puzzle, it is explicitly stated:
"One person sits between S and V."

Therefore, S and V share the exact same positional relationship of having one person seated between them. Thus, S is related to V.
