What will be the value of aggregate demand in an economy with the following data:

Autonomous investment 200 crore
Marginal propensity to save 0.3
Level of income 5000 crore
Autonomous consumption expenditure 50 crore
Options:

2750

6550

3750

1750

Correct Answer:

3750

Explanation:

The aggregate demand function is:

AD = C + I

AD = c̅ + bY + I

AD = 50 + 0.7 (5000) + 200

AD= 50 + 3500 + 200

AD = 3750
