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:

let 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

Answer:

Let the number of row be x

Let the number of student in each row be x

And the 9 students are left out

The total students are 6250

${x}^{2} - 9 = 6250 \\ {x}^{2} = 6250 - 9 \\ {x}^{2} = 6241 \\ x = \sqrt{6241} \\ x = 79$

Hence there are 79 rows and each row 79 students
