The ratio of:
a) Hema expenditure to salary is 17:30.
b. his savings to salary is 13:30.
c. his expenditure to savings is 17:13.
We can calculate the ratios in the following ways:
a) Expenditure to Salary Ratio:
Hema's expenditure is the difference between his salary and savings: 18,000 - 7,800 = 10,200.
We shall calculate the ratio by dividing the expenditure by the salary: 10,200 / 18000 = 17 / 30 = 17:30
Thus, Hema's expenditure to salary is 17:30.
b. Savings to Salary Ratio:
We shall estimate the ratio of savings to salary by dividing Hema's savings by his salary. 7800 / 18000 13/30 = 13:30
So, his ratio of savings to salary is 13:30.
c. Expenditure to Savings Ratio:
The ratio of expenditure to savings is calculated by dividing Hema's expenditure by his savings.
10,200 / 7800 = 17/13 = 17:13
Hence, Hema's ratio of expenditure to savings is 17:13
