Question

Rs.600 were divided among a certain no.of persons. Had there been 15 persons, each would have got rs.30 less. Find the original no. of persons. if you know the answer then tell or get lost​

Answer 1

Answer:

let the no of persons be x

According to the question

600/x -30= 600/x+15

600-30x/x= 600/x+15

by using cross multiplication

we get

(x+15) (600-30x) = 600

600x-30x^2 + 9000 - 450x = 600x

-30x^2 -450x +9000

Divide all the terms by -30

x^2+150x-300 splitting the middle term

we get

x =20
