Question

There are 2450 children in a school. For a P.T. drill they have to stand in such a manner that number of rows is twice the number of students in each row. Find the number of students in each row. ​

Answer 1

Answer:

There are 35 students in each row.

Step-by-step explanation:

Let the number of student in each row be x.

No. of rows is twice the no. of students in each row.

So, no. of rows = 2 * no. of students in each row

= 2 * x

= 2x

Total no. of students = No. of rows * No. of

students in each row

2450 = 2x * x

2450 = 2x²

2x² = 2450

x² = 2450/2

x² = 1225

x = √1225

x = 35

No. of students in each row = x

= 35
