The price elasticity of demand of good x is half the price elasticity of demand of good y. A 25% rise in price of good y reduces its demand from 400 to 300 units. Percentage change in demand of good x when its price falls from ₹10 to ₹8 per units.

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.

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.

The price elasticity of demand of a good is (-) 0.5. At a price fo ₹ 20 per unit its demand is 300 units. At what price will its demand increase by 10 percent ?

Suppose price elasticity of demand for a good is -0.2. if there is 5% increase in price of the good, by what percentage will the demand for the good go down ?

The price elasticity of demand for good X is knownto be twice that of good Y. Price of X falls by 5 % while of good Y rises by 5% . What is the percentage change in the quantities demanded of X and Y ?

Price elasticity of demand of a good is (-)1 . When its price falls by one rupee , its demand rises from 16 to 18 units . Calculate the price before change.

The price elasticity of demand of X is (-) 1.25. its price falls from ₹ 10 to ₹8 per unit. Calculate percentrage change in its demand.

Price elasticty of demand of good X is -2 and of good Y is -3. which of the two goods is more price elastic and why ?
