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 ?

Answer»

30
40
25
20

Solution :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.
