Let there were x students, then contribution of one student = 500x500x
Contribution of each student when 5 of them have left = 5000x−55000x−5
Given, 500x−5−500x500x−5−500x = 5
= 5
using options, we find x = 25 satisfies the equation.
Therefore, number of students who attended the picnic = (25 - 5) = 20
