Question

If incomes of a, b and c are in the ratios of 7 : 9 : 12 and their expenses are 8 : 9 : 15 if a saves 1/4 of his income. Find the ratio of their savings

Answer 1

Answer:

Step-by-step explanation:

The incomes of A, B and C can be taken as 7x, 9x and 12 x. Similarly, the expenditures can be taken as 8y, 9y and 15y.

Given A saves 1/4 of his income.

i.e., 7x-8y = 7x/4 . So we get y = 21x/32

Savings of A = 7x-8y = 7x/4

Savings of B = 9x-9y = 99x/32

Savings of C = 12x-15y = 69x/32

So ratio of their savings = 56:99:69
