Question : 3 of 6
Marks: +1, -0
At the break-even point level of incomes for the economy is ₹ 10,000\text{₹}\,10,000 crores and if the people tends to save 20 per cent of their additional income, then calculate the value of autonomous consumption.
Solution:  
C=C‾+ by C = \overline{C} + \text{ by } [ At Break even point] \text{[ At Break even point] }
10,000=C‾+0⋅8(10,000)10,000 = \overline{C} + 0 \cdot 8(10,000)
10,000=C‾+8,00010,000 = \overline{C} + 8,000
10,000−8,000=C‾=₹ 2000 crores 10,000 - 8,000 = \overline{C} = \text{₹}\,2000 \text{ crores }
Working Notes:
b=MPCb = \text{MPC}
C=YC = Y
∵S=0\because S = 0
∴C=10,000\therefore C = 10,000
MPS=0⋅2 (given) \text{MPS} = 0 \cdot 2 \text{ (given) }
MPC=1−MPS\text{MPC} = 1 - \text{MPS}
=1−0⋅2=0−8= 1 - 0 \cdot 2 = 0 - 8
