How many children are there between P and Q in a row of children ?
Statements:
1. P is fifteenth from the left in the row.
2. Q is exactly in the middle and there are ten children towards his right.
Answer: D
From 2, Q being in the middle, there are 10 children to his right as well as to his left. So, Q is 11th from the left. From 1, P is 15th from the left.
Thus, from both 1 and 2, we conclude that there are 3 children between P and Q.
