Directions: Eight persons S, T, U, V, W, X, Y and Z sit around a circular table, equally spaced, all facing the centre (not necessarily in the same order).T sits third to the right of S.W sits third to the right of Z.X sits second to the left of Z.Y…

Answer: D. Third to the right

Answer: (D) Third to the right

Fix S; T is third to the right of S. Z, W (third to the right of Z) and X (second to the left of Z) can be placed in four ways. In three of them either Y cannot sit between W and U, or V is forced next to Z. The only valid placement puts Z opposite S, W immediately to the left of S and X immediately to the left of T; then Y and U take the two seats after W, and V sits immediately to the right of S.

Going clockwise from S: S, W, Y, U, Z, T, X, V. (When everyone faces the centre, a person's right is the anticlockwise direction and left is clockwise.)

From W, moving to the right (anticlockwise): S, V, X. So X is third to the right of W.
