Study the following information carefully and answer the questions:
Six people P, Q, R, S, T, and U are sitting on the ground in a hexagonal shape (not necessarily in the same order). All the sides of hexagon so formed, are of same length. P is not adjacent to Q or R; S is not adjacent to R or T; Q and R are adjacent; U is the middle of S and R. If one neighbour of P is S, who is the other one?

P is not adjacent to Q or R; S is not adjacent to R or T; Q and R are adjacent; U is the middle of S and R. If one neighbour of P is S, who is the other one?
Solution
U sits between S and R, giving the block S-U-R. Q is adjacent to R, extending it to S-U-R-Q. The two remaining seats lie between Q and S, and they must hold P and T. P cannot sit next to Q, so P takes the seat beside S and T takes the seat beside Q.
Thus P's neighbours are S and T, and the other neighbour is T.
