Question : 88 of 200

Marks: +1, -0

The earnings of A, B, C are in the ratio 7 : 9 : 12 and their expenditures are in the ratio 8:9 :15. If A saves 25% of his earnings, then the ratio of their savings is

46 : 99 : 59
56 : 99 : 69
69 : 56 : 99
59 : 46 : 99

Solution:

Let the incomes of A, B, C be 7x, 9x, 12x respectively and their corresponding expenditures 8y, 9y and 15y.
Saving = Income – Expenditure

⇒7x-8y={1}/{4}(7x)⇒21x=32y⇒y={21}/{32}x

A’s saving

={7x}/4=56/32x

B’s saving

=9x–9y=9(x–y)

=9(x-{21}/{32}x)={9×11}/{32}x={99}/{32}x

C’s saving

=12x–15y=12x-15×21/32x=69/32x

∴ Required savings ratio = 56 : 99 : 69
