The tax on the salary of C is $ \frac {1}{4}$ of the salary and savings are $\frac{1}{3}$ of the salary. The ratio of the expenditure to the savings is:

4 : 5 4 : 3 5 : 4 3 : 4

5 : 4

Expenditure = Salary - tax - savings  Let the salary of C = 12 According to the question,  tax       = \(\frac{1}{4}\)x12 =3 savings = \(\frac{1}{3}\)x12 =4 Expenditure = 12 - 3 - 4 = 5 Ratio of expenditure to savings = 5 : 4
