Students of a class collected as many paisa from each student of class as is the number of students in that class. If total collection is Rs. 59.29, then find the total number of students in the class.

  • A.55
  • B.65
  • C.77
  • D.80

Answer: C

Each student gives as many paise as there are students, so the total is the square of the number of students.

\[ \text{Rs. } 59.29 = 5929 \text{ paise} \]

\[ \sqrt{5929} = 77 \]
