Answer 2

He spends Rs. 5760 on household expenses and saves Rs. 1440

Explanation:

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics.When determining a number percentage, we should divide it by 100 before multiplying the result by 100. As a result, the proportion refers to a component per 100. The word per cent denotes a percentage of 100. The word "percent" is used to symbolise it.

Given the monthly income of 'a' is Rs. 7200

Given he spends 80% of his salary on household expenses

$\rightarrow 80\% \ of\ Rs.7200=\frac{80}{100}\times 7200\\\therefore \ Household\ expenses=Rs. 5760$

$\ Savings= Monthly\ income-Household\ expenses\\\therefore Savings= Rs.7200-Rs.5760=Rs.1440$
