Hint: We will use the concepts of basic algebra to solve the problem. Also, we will be using concepts of a number of problems to further solve the question.

Complete step-by-step solution

We have been given that during a mass drill exercise 6250 students of different schools are arranged in a row, So, Total number of students = 6250

Also, we have been given that the number of students in each row is equal to the number of rows.

So, let us take that number of rows = x

The number of students in each row = x

Now, we have been given that after making the number of students and number of rows equal, 9 students are left out. So, we can write,

x2+9=6250x2=6250−9x2=6241x=6241−−−−√x=79

Therefore, the number of children in each row is 79.
