Answer 1

Given that,

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

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

Ratio of Income : Expenditure $=15000:9000$

Lowest form of $=15000:9000=\frac{15000}{9000}=\frac{5}{3}=5:3$ ( Divide both $15000$and $9000$ by their HCF $300$)

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