Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Solution}}}}}}$

Given:

1. Total amount donated = Rs.7225

2. Amount donated by each child = No of students in class

To Find:

Number of students in the class

Solution:

Let the total number of students be x.

As the number of students and amount donated by each students is same, hence amount donated by each child is also x.

So,

Total Amount = No. of students * Amount donated by each child

7225 = x * x

$x^2\:=\: 7225$

x = $\sqrt{7225}$

x = $\sqrt{85*85}$

x = 85.

So, the total students in the class are 85.

Hope it helps!!!!
