Question

9. 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.

pls give me correct answer​

Answer 1

Solution

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.
