Question
Who sits second to the right of
V? Seven persons P, Q, R, S, T, U and V sit in a linear row and face in the north direction but not necessarily in the same order. T sits third to the right of S. T sits second to the left of U. Four persons sit between V and Q. V doesn't sit at any of the ends of the row. P doesn't sit adjacent to R.Solution
T sits third to the right of S. T sits second to the left of U. We have two cases, first, when S sits at extreme left end and second, when S sits second from one of the extreme ends. Case 1: When S sits at extreme left end. S ____Â _____Â T _____ U ____ Case 2: When S sits at second from the left end. _____ S ____Â _____Â T _____ U Four persons sit between V and Q. V doesn't sit at any of the ends of the row. In case 1, Q sits at extreme right end. In case 2, Q sits at extreme left end. Case 1: When S sits at extreme left end.
