A.	12	B.	13
C.	14	D.	15
E.	None of these

Answer and Explanation

Answer:14

Explanation:
Q is 9th from the right end and R is fourth to the left of Q. So, R is 13th from the right end.
Number of children to the left of R = (40 — 13) = 27.
Thus, R is 28th from the left end. Also, P is 13th from the left end.
Clearly, there are 14, persons between P and R.
