Solution

Consider that the donated Rs is x, then as it is given that each student donated as many rupees as the number of students, then the number of students will also be x.

Therefore, One student donate Rsx.

x student will donate x×x=x2.

So, x2=2401

x=2401

x=49

Therefore, there are 49 students in the class.
