Some students planned a picnic. The total budget for picnic was Rs 2000 but 5 students failed to attend the picnic and thus the contribution for each student is increased by Rs 20.



What is the number of students planned for picnic ?

Options

A. 30
B. 40
C. 25
D. 20

Answer

C

Explanation

We have `" "x^(2)-5x-500=0`
`x^(2)-25x+20x-500=0`
`(x-25)+20(x-25)=0`
`(x-25)(x+20)=0`
`x=25,-20`
Thus ( c ) is correct option.
