Question

There are 1000 students in a school that the number of rows is equal to number of columns. How many students would be left out in the arrangement.​

Answer 1

There are students = 1000

The closest perfect root to 1000 is 961 which is = 31

There will be rows and columns = 31

So 1000 - 961 = 31

::  There will be 31 rows and columns and 39 students will be left out.
