Six friends, P, Q, R, S, T and U, are sitting around a circular table, facing the centre of the table. P is second to right of S. Q is sitting to the immediate left of T. P is sitting between R and U. S is sitting to the immediate left of R. Who is sitting between P and S?

Let's trace the positions around the circular table clockwise/counter-clockwise based on the constraints: P is second to the right of S. If we place S at position 1, then P is at position 3 (going counter-clockwise/right).S is sitting to the immediate left of R. This means R is to the immediate right of S, so R is at position 2.P is sitting between R and U. Since R is at position 2 and P is at position 3, U must be at position 4.Q is sitting to the immediate left of T. The remaining two spots are positions 5 and 6. For Q to be to the immediate left of T (facing center), T must be at position 5 and Q at position 6.Let's double check the question: "Who is sitting between P and S?"Looking at our arrangement:Position 1: SPosition 2: RPosition 3: PThus, R is sitting directly between P and S.
