Question

annual income of X and Y are in the ratio of 4 : 3 and their expenses are in the ratio of 3 : 2 if each of them saves Rs . 600 by the end of year , what is the annual income of X and Y ?

Answer 1

let the incomes of x and y be 4x and 3x respectively.
let the expense be 3x and 2x respectively


income of x- expense of x=savings of x.
4x -3x=600
x=600
income of x=4x=₹(600×4)=₹2400

income of y- expense of y= savings of y
3x-2x=600
x=600

income of y=3x=₹(600×3)
=₹1800
