Puzzle :-
Eight friends M, N, O, P, Q, R, S and T are sitting around a circular table with equal distance between them bur not necessarily in the same order. Some of them are facing the centre with some face outside (i.e. opposite to centre) O sits second to the right of R, R faces the centre. Only two people sit between O and N (either form O’s right or O’s left) S sits second to the right of O T sits to the immediate right of N. S and N face opposite direction (i.e. if N faces the centre then S faces outside and vice versa) Immediate neighbor of S face the same direction (i.e. If one neighbor faces the centre then the other also faces the centre and vice-versa Only three people sit between P and Q Neither P nor M is an immediate neighbor of R. Q sits second to the right of m Both T and Q faces face a direction opposite to that of O (i.e. if O faces the centre then both T and Q face outside and vice-versa)
Directions :-
