Detailed Solution

Concept- The number of rows and columns of P.T. is a  drill. It then first decomposes the (student's) numbers as the product of those factors, and then forms a number pair. The number of unpairable students remaining in the product is the number of students excluded in this placement.
Here, Number of children = 500
Question ImageBy getting the square root of this number, we get,
There are 22 youngsters on each row.
And the left out children are 16.
Hence, the correct option is 1.
