Study the following information and answer the questions given below:
Twelve people are standing in two parallel rows each row having 6 people. P, Q, R, S, T and U are standing in row 1 facing south while A, B, C, D, E and F are standing in row 2 facing north. They are standing in such a way that there is an equal distance between two adjacent persons. Thus each person from row 1 is facing another person from row 2.
D is standing third to the right of E. C is standing third to the right of A. A and E are not immediate neighbours. U is facing the one who is to the immediate right of C. T is standing fourth to the left of S. B is not facing U. R is standing third to the left of P.
