Given Information: Autonomous consumption $(\overline{C})=100$ Marginal Propensity to Consume $(\text{MPC})=0.6$ Equilibrium level of Income( $Y$ ) $=\text{₹}\,2000$ Autonomous Investment $(I)=\text{₹}\,300$ At equilibrium level, $Y=C+I$ Thus,$\text{₹}\,2000=\text{₹}\,1300+I$ $I=\text{₹}(2000-1300)$ $I=\text{₹}\,700$ At this level of income, $Y$ should be $\text{₹}\,700$ but it is given $\text{₹}\,300$ which is not valid.Working Note: $C=\overline{C}+bY$ $=\text{₹}100+0.6(2000)$ $=\text{₹}100+1200$ $=\text{₹}1300$
