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

Answer:

so if we make 25 rows an each row contain25 student s

Answer 2

Answer:

if number of rows=no of students in a row=x

then x= a number whose square is less than 500 and nearest to it because 500 is not a perfect square itself

the nearest square to 500 is 22^2 that is 484.

16 students are left out.
