Question

Q. the annual salary of a & b are in the ratio of 5 : 4 and their annual expenses bear a ratio of 4 : 3. if each of them saves rs. 800 at the end of year. find their incomes.

Answer 1

Income of a = 5x
income of b = 4x
spending of a = 4x
spending of b = 3x
income of a = spends + savings
5x = 4x + 800 Rs
5x-4x = 800
x = 800
income of a = 800×5 = 4000 Rs
income of b = 800 ×4 = 3200 Rs
