Ten persons are sitting in two parallel rows. Persons - A, B, C, D, and E sit in row 2 facing towards the south direction and persons - P, Q, R, S, and T sit in row 1 facing towards the north direction.
C sits third to the left of D.
The one who sits immediate right S faces C.

Two persons sit between S and R.
Thus, Case 2 gets cancelled.

P sits second to the left of Q.

The one who sits opposite to T sits second to the right of A.

R does not sits opposite to E.

This is the final arrangement.
The one who sits immediate right of D sits opposite to R.
