Fifty children stand in a row facing north. Kavya is 10th from the left end and Rohan is 18th from the right end. How many children stand between Kavya and Rohan?

Explanation

1. 01

   Rohan's position from the left $= 50 - 18 + 1 = 33$.

2. 02

   Kavya is at 10 and Rohan at 33, so the children between them are those at 11 to 32.

3. 03

   Between $= 33 - 10 - 1 = 22$.
