Four boys R, S, T and U are sitting in a row, facing towards the south (but not necessarily in the same order). Four girls A, B, C and D are sitting in a row, facing towards the face of these boys (but not necessarily in the same order). C and R are diagonally opposite to each other. A and S are diagonally opposite to each other. T is the immediate neighbour of R. D is the immediate neighbour of C. Who is facing D?

U

Answer: U

In this question you need to first place C and R, then place A and S, and then place D and T
