Answer»

Solution :Atequilibriumlevel
AD= AS = National icome (Y)
So,AD = Y + C+I
GivenC= 40 + + 0.75 Y
` Y = (40 + 0.75 Y) + 60`
or ` Y - 0.75 Y = 100or0.25 Y = 100or Y =(100)/(0.25)= 400`
EQUILIBRIUM level of income = ₹ 400 CRORE.
(B) Putting the value of Y = 400 in the consumption function `(= 40 + 0.75Y)`we get
`C = 40 + (0.75) (400) = ₹ 340` crore
Levelof consumption at equilibrum= ₹ 340 crore.
(c) Saving (S)= Inome(Y) -Consumption(C)
(S) = 400-340 = 60
Level of saving at equilibrium = ₹60 crore.
