Question

%. 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 1

Step-by-step explanation:

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.

Answer 2

Answer:

16 children would be leftout

Step-by-step explanation:

let the number of rows and columns be x

then x*x =500

x2=500

x=

$\sqrt{500}$

by long division method...

16 children.

and as 484 is a square of 22.
