Qs = 2P or Ps = 0.5Q, Qd = 300 - P or Pd = 300 - Q.

In equilibrium Qd = Qs, so:

300 - P = 2P,

P = 100,

Q = 2×100 = 200 units.


a. If government imposes a price ceiling of Rs.50 on lentils, then the consumer and producer surplus at the ceiled price are:

Q = 2×50 = 100 units.

CS=100×((30050)+(25050))/2=22,500.CS = 100×((300 - 50) + (250 - 50))/2 = 22,500.

PS=0.5×100×50=2,500.PS = 0.5×100×50 = 2,500.


b. The dead weight loss is:

DWL=0.5×(200100)×(25050)=10,000.DWL = 0.5×(200 - 100)×(250 - 50) = 10,000.
