Answer 1

Answer:

Let's take his monthly income be 60x . Donation given to NGO =>1/5(60x) => 12x.

Money spent on food =>1/4(60x) => 15x.

Money spent on rent =>1/3(60x) =>20x. Money spent on other expenses =>1/15(60x) =>4x. Money left = 60x-12x-15x

-20x-4x => 9x = 9000 => x =1000 So his monthly salary => 60000 ruppees.
