Question

15
There are 2028 students in a school. The teacher wants them to stand in rows
and columns in such a way that the number of rows and columns remains the
same. Find the number of students left out.

Answer 1

Answer:3 students

Step-by-step explanation:

Let the number of students in each row and column be x. And number of students who are left out be a .

A.T.Q

x*x=2028-a. (x² should be 2028 or less than it.)

So, x =45 as (45)² is equal to 2025 and 3 students are left out.
