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 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 ?

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

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.

Quantity demanded of a commodity rises by 6 units when its price falls by ₹1 per unit its price elasticity of demand is (-)1. if the price before change was ₹20 per unit, calculate quantity demanded at this price.

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 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.
