From the data given below about an economy. Calculate:
(i) Investment expenditure.
(ii) Consumption expenditure.
(a) Equilibrium level of income Rs. 5000
(b) Autonomous consumption Rs. 500
© Marginal Propensity to Consume Rs.0.4

(i) Y=C +I, 5000 = 2500 +I [C = 2500 from (ii)]
I = 5000 - 2500 = 2500
(ii) C= $\overline{C}$ + bY ( b = MPC)
= 500+0.4 x 5000 = 500 + 2000 = 2500
