Question

Each student of a class contributed as many rupees as the number of students in the class for the welfare of the poor people in the locality . the total contributed amount Rs 1024 . find the number of students in the class

Answer 1

Let the no. of students be x 
then the amount contributed by each of them will also be x ( given)
total amount collected = 1024 
this means x into x is 1024 
x square is 1024 
so taking the underroot of 1024 - 
x = 32 
so the no. of students is 32.
