Concept:The ratio of two expenditures is found by dividing both amounts by their highest common factor to obtain the simplest whole-number form.Explanation:From the given data, the expenditure on health is $80$ and the expenditure on agriculture is $120$.Write the ratio as health to agriculture: $80 : 120$.Find the highest common factor of $80$ and $120$.The HCF is $40$.Divide both terms by $40$: $80 \div 40 = 2$ and $120 \div 40 = 3$.Thus, the simplified ratio is $2 : 3$.This is written as $2.3$ in the options.Answer:$2 : 3$ (Option A).
