Question

The students of class VIII of a school donated Rs. 2401 for PM's National Relief Fund. Each student donated as many rupees as the number of students in the class.

Answer 1

Total amount of donation = 2401
Let number of students in VIII = x
$\therefore$ Amount denoted by each student = Rs. x
$\therefore x\times x=2401\Rightarrow x^2=2401$
$\Rightarrow x=\sqrt{2401}=\sqrt{7\times 7\times 7\times 7}$

$7\times 7=49$
Number of students of class VIII= 49
