following is the demand schedule of commodity Y:
Calculate the elasticity of demand when ,(i) price rises from ₹ 15 to ₹ 20 , (ii) when price falls from ₹ 20 to ₹ 15 .

from the following data, calculate price elasticity of demand.

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.

The price elasticity of demand of good X si double the price elasticity of demand of Good Y . A 10% rise in the price of good Y results in fall in its demand by 60 units. If original demand of commodity Y was 400, calculate percentage rise in quantity demanded of good X when its when its price falls from ₹ 10 to ₹ 8 per unit.

Calculate the price elasticity of demand for a commodity when its price increase by 25% and quantity demanded falls from 150 units to units.

When price of a commodity X falls by 10 per cent, its demand rises from 150 units to 180 units. Calculate its price elasticity of demand . How much should be the percentage fall in its price so that its demand rises from 150 to 210 units.

When price of a commodity X falls by 10 percent , its demand rises from 150 units to 180 units. Calculate its price elasticity of demand . How much should be the percentage fall in its price so that its demand rises from 150 to 210 units.

When price of a commodity X falls by 10%, its demand rises from 150 units to 180 units. Calculate its price elasticity of demand. How much should be the percenyage fall in its price so that its demand rises from 150 to 210 units.

The price elasticity of demand of commodity X is 1/2 of price elasticity of demand of commodity. When price of X falls by 40% , its demand rises by 20 units. Calculate price elasticity of demand of commodity X and Y, it originally 100 units of X were demanded at price of ₹ 5 per unit.
