Instruction : All questions carry equal marks. 1 (a) Explain the demand law and demand function. 6 (b) The demand law of a commodity is P = ajx + b. When 14 the price of commodity was Rs. 4, then demand was 40 units. When the price becomes Rs. 6, then demand comes to 30 units. Find the value of a and b. Find actual mod of demand. Draw the demand curve and find the demand, for price Rs. 8 1 (a) Explain the elasticity of demand and its different 14 methods. (b) If the demand law is d = 24 - Jp, then obtain the 6 value of elasticity of demand at price P = 25. (a) What is market equilibrium ? Explain importance in reference of demand and price. Explain the impact of tax on equilibrium with diagrams. Find the equilibrium price and demand of the following functions : 2 12 (b) 8 Demand function (1) D = 55 - 2 P (1) (2) D = 26 - 2 P (2) OR What is Revenue ?
