Question

The ratio of the incomes of two friends anjali and abdul is 9:7 and the ratio of their expen-ditures is 4:3. If each of them saves 4000 per month, find their monthly incomes. Also, if each of them donates 1% of her/his income to a charity working for old age destitutes, find the resulting savings of each. What value is indicated from this action?

Answer 1

Answer:

Ratio of their savings is 9:7 - 4:3 = 5:4

so , let the savings be 5x and 4x

then 5x = 4000

X = 4000/5

X = 800
