$\large\blue{\boxed{\mathcal 15:18:11}}$

$\huge\underline\orange{\mathcal Solution}$

The income of A B and C are in ratio of =12:9:7

Expenditure are in ratio of =15:9:8

Let,

The income of A B and C are = 12x, 9x,7x

Their expenditure are = 15y , 9y, 8y

Saved 25% of his income

Expenditure=> 15y = 75% of income

15 y = 75(12x)/100

15y = 75(12x)/100

15y =3(12x)/4

15y =9x

y =9x/15

y =3x/5

The savings of A B and C are :-

12x - 15y , 9x - 9y and 7x - 8y

Now putting value of "y"

12x - 9(3x)/5

9x - 9(3x)/5

7x - 8(3x)/5

3x , 18x/5 , 11x/5

Ratio :- 15 : 18 : 11

$\huge{\boxed{\mathcal 15:18:11}}$
