B. Q
C. R
D. P
A. S
B. Q
C. R
D. P
Best answer
Answer: D. P
Answer: (D) P
S takes the right end, so R (not at an end) must be in the 2nd or 3rd seat.
P and Q need two adjacent seats with Q on the right. If R were 2nd, P and Q would need seats 3 and 4, but S is 4th. So R is 3rd and P, Q are 1st and 2nd.
Arrangement (left to right): P Q R S. P is at the extreme left.
