Ans. First we shall calculate the multiplier
Multiplier = 1/1-MPC = 1/ 1 - 0.9 = 1/ 0.1 = 10
Thus for every $1 spent by government, the output will increase by $10.
So in order to achieve equilibrium, we need $200 increase in output which can be done by increasing govt spending by $20 (as multiplier is 10).
First blank - increase
Second blank - $20
