Question

Rashi saves $Rs.900$ per month month from her salary of $Rs.7200$. Find the ratio of her.
a. income to savings
b. expenditure to income
c. savings to expenditure

Answer 1

Income of Rashi $=Rs.7200$

Savings per month $=Rs.900$

Expenditure per month $=7200-900=Rs.6300$

Therefore,

Ratio of income to savings $=\frac{7200}{900}=\frac{900\times 8}{900\times 1}=\frac{8}{1}$

Ratio of expenditure to income $=\frac{6300}{7200}=\frac{900\times 7}{900\times 8}=\frac{7}{8}$

Ratio of savings to expenditure $=\frac{900}{6300}=\frac{900\times 1}{900\times 7}=\frac{1}{7}$
