Five people P, Q, R, S and T are standing in a queue. R is standing between P and T. P is just behind Q and Q is second in the queue. Who is second last in the queue?

Let the five people are standing in line from West to East facing West.

R is standing between P and T. The two possibilities are

(i) P, R, T

(ii) T, R, P

P is just behind Q and Q is second in the queue. In the second possibility, Q cannot be placed. Hence possibility (ii) is eliminated. The remaining possibility is

(i) _ , Q, P, R, T

The remaining person S is placed remaining first place. The final arrangement will be

S, Q, P, R, T

$$\therefore\ $$R is second last in the queue

Hence, the correct answer is Option C
