Question

The students of a class arranged a picnic. Each student contributed as many rupees as the number of students in the class. If the total contribution is Rs. 1156, find the strength of the class.

Answer 1

Let no. of students in the class=x
Then contribution of each student= x
$\therefore x\times x=1156\Rightarrow x^2=1156$

$\therefore x=\sqrt{1156}=\sqrt{\overline{2\times 2}\times \overline{17\times 17}}$
=$2\times 17=34$
