The demand function of a commodity is `Q_(d) = 50-10P`. Find out the level of demand when price of the commodity is (i) Rs. 3 , (ii) Rs. 2.

The demand function of a good is Q_(d) = 600-25P . Find out the level of demand when price will be (i) Rs. 5, (ii) Rs. 10.

The demand function of good X is Q_(d) = 100-10P , find out the price of X when quantity demanded is (i) 20 units, (ii) 15 units, (iii) 0 units.

Demand function of the good X is D_(X)=60-10P . Find out the price of X when demand will be: (i) 20 units (ii) 10 units (iii) 0 units.

The demand function of a commodity x is given by Q_(X) = 20 - 3P_(X) . Find out the values of P_(X) , when corresponding values of Q_(X) are given as : 5, 8, 11 and 14.

The demand function of a commodity x is Q_(x)=12-P_(x) (where Q_(x) = the quantity demanded of a commodity x and P_(x) = price of the commodity x). Derive the TR and MR schedules when the price of commodity varies from ₹ 12 to ₹ 1.

The demand function of a commodity x is given by Q_(x) = 12 - 2P_(x) . Prepare the demand schedule, if its price various from Rs 6 to Re. 1 :

The demand funcation of Commodity 'X' is given as : Q_(x)= 20 - 2P_(x) . Calculate its price elasticity of demand when price falls from ₹ 5 to ₹3.
