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 children are left out.

Find the number of children in each row of the

square.​

Answer 1

Answer:

79 students in each row

Step-by-step explanation:

Say number of students in each row = x

Number of rows = x

According to given equation-

${x}^{2} = 6250 - 9$

$x = \sqrt[2]{6241}$

$x = 79$

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