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 ?

The price elasticity of demand of a commodity is -0.5 . At a price of ₹ 20 per unit, total expenditure on it is ₹ 2,000. its price is reduced by 10 per cent. Calculate its demand at the reduced rate.

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.

The coefficient of price elasticity of demand for a commodity is 0.2. when price was ₹ 10 per unit. The quantity demanded was 40 units. If the price falls to ₹ 5 per unit, how much will be its quantity demanded ?

The price elasticity of demand for a good is -0.4 if its price increases by 5 percent, by what percentage will its demand fall ? Calculate.

price elasticity of demand of a good is -0.75. calculate the percentage fall in its price that will result in 15 per cent rise in its demand.

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.

Price elasticity of demand of a good is (-)1 . Calculate the percentage change in price that will raise demand from 20 units to 30 units.
