Question : The students of a class donated a sum of INR 2,809 to the Fund. Each student donated as many rupees as the number of students in the class. The number of students in the class is:
Option 1: 49
Option 2: 53
Option 3: 51
Option 4: 47
Correct Answer: 53
Solution :
Let the total number of students be $x$.
Each student will donate = $x$
Total fund = donation of each student × total number of students
⇒ $2809 = x \times x$
⇒ $2809 = x^2$
⇒ $x = 53$
Hence, the correct answer is 53.
