The students of Class of a school donated Rs.1225 for Prime Minister’s National Relief Fund. Each student donated as many rupees as the number of students in the class .Find the number of students in the class.​

Answer 1

Solution :-

Let x be the number of students in the class.

Thus, amount deposited by a student is Rs. x

If, each student deposits Rs. x for Prime Ministers National Relief Fund in a class of x students, then the total sum donated by the class =x²
