Eight persons - L, M, N, D, P, Q, R and S are sitting around a circular table, but not necessarily in the same order, four of them are facing inside and the other four are facing outside.

S is sitting at an angle of π/2 radians left of M who is facing inwards. P and R are facing the opposite directions and are sitting at an angle of π radian to each other. D is sitting at an angle of 3π/4 radians to the right of L. D is the neighbour of S and he forms the angle of 3π/4 radians with M. R who is facing inwards is sitting between L and N. Not more than 2 persons who are sitting together are facing the same direction. P and S are facing the same directions.
