Explanation: 

Detailed explanation-1: -The price elasticity of demand evaluates the responsiveness of consumers to changes in the price of a product. In other words, it measures how the quantity demanded of a given good or service reacts to the price change. If the change in quantity is greater than the price change, we say the demand is elastic.

Detailed explanation-2: -We say that demand is inelastic when quantity demanded changes just a little when the price changes; more precisely, the percentage change in quantity demanded is less than the percentage change in price. In this case, quantity demanded is not very responsive to changes in price.

Detailed explanation-3: -In case of perfectly inelastic demand the change in price will have no effect on the quantity demanded. The consumers do not change their demand due to the change in price. This usually is seen in case of necessities. Hence, the equilibrium quantity will be same the price might increase or decrease.

Detailed explanation-4: -The price elasticity of demand is calculated as the percentage change in quantity divided by the percentage change in price.
