Question : 7 of 49
Marks: +1, -0
If in an economy, the Investment Multiplier is 4 and Autonomous Consumption is 30\text{₹}\,30 crore, the relevant consumption function would be ________.
(Fill up the blank with correct alternative)
Solution:  
(a) C=30+0.75YC=30+0.75 Y
Explanation: Investment Multiplier (k)=4(k)=4
Autonomous Consumption (C)=30(\overline{C})=\text{₹}\,30 crore
K  =  11MPCK\;=\;\frac{1}{1 - MPC}
4  =  11MPC4\;=\;\frac{1}{1 - MPC}
MPC  =  14MPC\;=\;\frac{1}{4}
MPC  =0.25MPC\;=0.25
MPC  =10.25MPC\;=1-0.25
MPC  =0.75MPC\;=0.75
Consumption Function:
  C=C+MPC(Y)\; C = \overline{C} + MPC(Y)
  C=30+0.75Y\; C = 30 + 0.75 Y
