Question

Q.38. 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

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 = √6241

x=79.

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

Answer 2

Say number of students in each row =n

Number of rows =n

According to given equation-

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

$n {}^{2} = 6241$

$n = \sqrt{6241}$

$n = 79$

So, number of Children in each row of the Square is 79 and the same number of row were formed.
