There is only one correct way to arrange twelve people into two rows using the following rules:
Six people A,B,C,D,E and F are sitting in row-1 facing North, and six people P,Q,R,S,T and U are sitting in row-2 facing South, but not necessarily in this order.
Row-2 is above row-1, so every person from one row faces a different person from the other row.
The following information is known about them.
1) B is to the immediate left of C, who does not face Q. Q is third to the left of R.
2) Neither Q nor C sit at the ends. B is to the right of F and D.
3) D faces the person who is third to the right of T, who faces E.
4) P sits second to the left of the person who faces A.
5) S is not an immediate neighbor of P.
