(c) Rs. 35

Answer Key


Exp. At Equilibrium, Demand=Supply

Thus,   67500-18P=22500+12P


Equilibrium Price P =1500.




Exp.  Marginal cost is the change in the opportunity cost that arises when the quantity produced is incremented by one unit, that is, it is the cost of producing one more unit of a good.

Total amount paid to 8 craftsman before demand of 9th craftsman = 8 ×400


Total amount paid to 9 craftsman after demand of 9th craftsman    =9×450


Marginal cost=4050-3200



Exp. Unemployment resulting from industrial reorganization, typically due to technological change, rather than fluctuations in supply or demand is called Structural unemployment.


Exp. Elasticity =% Change in quantity/%Change in price

1.25 =X/6.4

X   = 6.4*1.25



Exp. Economic Profit=Accounting Profit- Implicit Cost

60= Accounting Profit – 18.5

Accounting Profit = 78.5 Crores.


Exp.If tea companies start using mechanised tea leave pickers then wages for manual tea leave pickers will fall.




Exp.A minimum wage is creates a price ceiling below which the wage cannot legally go.


Exp.The arc elasticity of demand can be calculated as:

Arc Elasticity = [(Qd2 – Qd1) / midpoint Qd] ÷ [(P2 – P1) / midpoint P]

Midpoint Qd = (Qd1 + Qd2)/2 = (4000 + 5000)/2 = 4500

Midpoint Price = (P1 + P2)/2 = (75 + 90)/2 = 82.5

% change in quantity demanded = (5000 – 4000)/4500 = 0.23

% change in price = (90-75)/82.5 = 0.18

Arc Elasticity of demand = 0.23/0.18 = 1.28.
