If price of a commodity rises from ₹ 8 to ₹10 per unit and its demand falls by 50% what is `e_(D)` ?

When price of good rises form ₹10 to ₹12 per unit its quantity demanded falls by 20%. Calculate its price elasticity of demand. How much would be the percentage change in its quantity demanded, if the price rises from ₹10 per units to ₹13 per units ?

Comment upon the degree of elasticty of demand for Good X, in the following given situation, if the price of the commodity rises from ₹5 per unit to ₹ 7 per unit and the quantity demand falls from 20 units to 16 units using proportionate method.

If price of a commodity rises by 40% and accordingly its demand fallss by 80% what is P_(e_(D)

When price of a good rises from ₹5 to ₹6 per unit, its demand falls from 20 units to 10 units. Compare the expenditure on the good to determine whether demand is elasic or inelastic

If price of a good rises from ₹ 46 to ₹ 50 per unit, the demand decreases from 30 units to 15 units. Calculate co-efficient of price elasticity of demand.

When price of a commodity A falls from ₹ 10 to ₹5 per units, its quantity demanded doubles. Calculate its elasticity of demand : At what price will its quantity demanded fall by 50%.

When price of a good falls from ₹ 15 per unit to ₹ 12 per unit, its demand rises by 25% , calculate P.e_(D)

(a) Arrange the following coeffcients of price elasticy of demand in ascending order: - 0.87, 0.53, -3.1,-0.80 , (b) Comment upon the degree of elasticity of demand for commodity X, if the price of the commodity falls from ₹ 28 per unit to ₹ 23 per unit and its quantity demanded rises from 50 units to 100 units.

Price of a good rises from ₹ 10 to ₹ 12 and its demand falls from 120 units to 100 units.Calculate price elasticity of demand.
