# Calculate Autonomous Consumption Expenditure from the Following Data About an Economy Which is in Equilibrium: National Income = 500 Marginal Propensity to Save = 0.30 Investment Expenditure = 100 - CBSE (Arts) Class 12 - Economics

#### Question

Calculate Autonomous Consumption Expenditure from the following data about an economy which is in equilibrium:
National income = 500
Marginal propensity to save = 0.30
Investment expenditure = 100

#### Solution

Given that

I = 100

Y = 500

MPS = 0.30

MPC = 1 - MPC = 1 - 0.30 = 0.70

As we know

Y = C + I

500 = barC + cY + I

500 = barC + 0.7 xx 500 + 100

C = 500

Therfore  barC = 50

Is there an error in this question or solution?
