Question

During a mass drill exercise, $6250$ students of different schools are arranged in rows such that the number of students in each row is equal to the number of rows. In doing so, the instructor finds out that $9$ students in each row of the square.

Answer 1

Say number of students in each row $=x$

Number of rows $=x$

According to given equation-

$x^2=6250-9$

$x=\sqrt{6241}$

$x=79.$

Hence, there are $79$ students in each row as well as $79$ rows.
