Answer 1

To find the percentage of saving.

It is given that a man spends $70\%$ of his income$.$

Consider his total income as $₹100$

Expenditure $=70\%$ of $₹100$

$=\frac{70}{100}\times 100$

$=₹70$

Saving $=$Income $-$ Expenditure

Saving $=100-70$

$=₹30$

Saving percentage $=\frac{30}{100}\times 100$

$=30\%$

Hence, a man save $30\%$ of his income.
