Study the following information to answer the given questions given below it.
N, O, P, Q, R, S, T and U are sitting around a circular area at equal distances from each other but not necessarily in the same order. Some of the people are facing the centre while some face outside, i.e., in a direction opposite to the centre.
R sits second to the right of T. T faces the centre. O sits third to the left of R. R and O face opposite directions. The immediate neighbours of O face the centre. P sits second to the right of O. U sits to the immediate left of P. N sits second to the left of Q. Q faces the same direction as O. Q is not an immediate neighbour of T. The immediate neighbours of R face opposite directions, i.e., if one neighbour faces the centre, the other neighbour faces outside.
