Answer:
t is given that there are 500 children in the school. They have to stand for a P.T. drill such that
the number of rows is equal to the number of columns.
The number of children who will be left out in this arrangement has to be calculated.
That is, the number which should be subtracted from 500 to make it a perfect square has to be
calculated.
The square root of 500 can be calculated by long division method as follows.
Required perfect square = 500 − 16 = 484
Thus, the number of children who will be left out is 16.
