Question

10. The students of Grade 8 of a school donated 4,761 for Chief Minister's
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

We need to calculate the square root of 4761 to get the solution.

By prime factorisation of 4761, we get

4761= 3*3*23*23

✓4761 = 3*23

= 69

There are 69 students, each contributing 69 rupees.
