Correct Answer - Option 4 : 2 ∶ 1
Given:
MP of wheat : MP of rice = 3 : 8
Consumption of wheat : Consumption of rice = 16 : 3
Concept Used:
Expenditure of commodity = Consumption of commodity × Rate of commodity
Calculation:
Expenditure of wheat = 3 × 16
⇒ Expenditure of wheat = 48
Expenditure of rice = 8 × 3
⇒ Expenditure of rice = 24
Ratio of Expenditure of wheat and rice,
⇒ 48 : 24
⇒ 2 : 1
∴ The ratio of expenditure is 2 : 1.
