There are 500 children in a school. For a P.T. drill they have to stand in such a manner that the number of rows is equal to number of columns. How many children would be left out in this arrangement.

Answer» As the number of rows is equal to the number of columns,
we can take a square root of the total number of children.
If we take the square root of `500`, we have a remainder `16`.
It means `484` children can be arranged in `22` rows and `22` columns and rest `16` will be left out.
