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?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → T
Since U sits between S and R, three seats run S – U – R, and because Q is adjacent to R the next seat is Q, giving S – U – R – Q round the hexagon. Two seats are left for P and T.
P may not sit beside Q, so the seat next to Q must go to T, and P takes the last seat, between T and S. P’s neighbours are therefore S and T, and every other condition is satisfied — S sits beside U and P, so it touches neither R nor T.
