Study the following information carefully to answer the given questions.
Eight people M, N, O, P, Q, R, S and T are sitting in a straight line with equal distances between each other,but not necessarily in the same order. Some of them are facing North and some of them are facing south.
1. M sits at one of the extreme ends of the line. Only three people sit between M and S. Q sits exactly between M and S.
2. T sits third to the right of Q. N is an immediate neighbour of T and faces south. O sits second to the right of R. O is not an immediate neighbour of S.
3. Immediate neighbour of S face opposite directions(i.e. if one neighbour faces North then the other neighbour faces south and Voce-Versa)
4.M and P face the same direction as Q(i.e if Q faces north then M and P also face North and Vice-Versa). Both the immediate neighbours of Q face south.
In the given arrangement, if two people come and sit to the immediate left of Q, how many people will sit between R and O?
