A man earns $Rs15000$ in a month. If he spends $Rs9000$, then

Expenditure : Income $=$______

Answer 1

Given that,

Total income of a men in a month $=Rs15000$

Total spend of a men in same month $=Rs9000$

Ratio of Expenditure : Income $=9000:15000$

Lowest form of $=9000:15000=\frac{9000}{15000}=\frac{3}{5}=3:5$ ( Divide both $9000$and $15000$ by their HCF $3000$)

Hence, Expenditure : Income $=$$3:5$
