Question

The income of a and b is in the ratio 4:3. their expenditure is in the ratio 3:2. if they both save $600 at the end of the year. find the annual income of each?

Answer 1

let their income be 4x and 3x
let their expenditure be 3y and 2y
income - exp = saving
so, 4x - 3y = 600
3x - 2y = 600
on solving
8x - 6y = 1200
- 9x + 6y = 1800
x = 600
y = 600
income of a = 4×600= 2400
income of b = 3×600 = 1800

Answer 2

28000 is the answer mate
