Suppose that originally, a product was being sold at ₹ 10 per unit and the quantity demanded was 1,000 units. The product price changes to ₹14 and, as a result, the quantity demanded changes to 500 units. Calculate the price ealstictiy of demand.

the price of a commondity is ₹ 12 per unit and its quantity demanded is 500 units. When price rises by ₹ 3 per unit, its quantity demanded falls by 150 units. Calculate its price elasticity of demand. Is demand elastic ?

At a price of ₹ 20 per unit, the quantity demanded of commodity is 300 units. If the price falls by 10% , its qunatity demanded rises by 60 units. Calculate its price elasticity.

At a price of Rs. 50 per unit the quantity demanded of a commodity is 1000 units . When its price falls by 10 percent , its quantity demanded rises to 1080 units . Calculate its price elasticity of demand . Is its demand inelastic ? Given reasons for your answer.

Price of a good rises from ₹ 7 per unit to ₹ 9 per unit but its demand remains unchanged. Calculate price ealsticity of demand.

A 5 per cent fall in the price of a good raises its demand from 300 units to 318 units. Calculate its price elasticity of demand.

Price of a good falls from ₹ 10 to ₹8. As a result, its demand rises from 80 units to 100 units. What is the price elasticity of demand ?
