Question

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

Answer 1

Let total no. of rows = x
so columns = x

Total of 500 students

So x*x = 500
x =
$\sqrt{500}$
so x =
${22}^{2} + 16$
hence there will be 22 rows, 22 columns and 16 students will be left out

Answer 2

Answer:

22 columns and 16 students will be left out

Hope this helps you out !!
