Answer to Question 2:
Unit Elastic: Suppose quantity sold of Apple goes down by 10 unit with increase in price by INR 10, then we can say, Apple has Elasticity equals to 1 (Elasticity= Change in Quantity/Change in price= 10/10=1)
Perfectly Elastic: There are no goods which are perfectly elastic. If you see the formula of Elasticity it is a ratio of Change in Quantity with change in Price and for perfectly elastic goods even small change in price would result in major change in quantity which might be infinity, which is impossible in real world. Hence for Perfectly Elastic goods, Elasticity=Infinity/0.00000…1=Infinity-->Not Possible
Perfectly Inelastic: This is again not possible. As Elasticity (E=Change in Q/Change in P) for perfectly inelastic goods is not defined, because for any huge change in price, there won’t be any change in quantity.
E=0.0000000…1/Infinity=Not defined and not possible.

Ok so what does elasticity of -1 (minus 1) means. does it also mean unit elastic.

plz also give examples of relatively elastic and relatively inelastic.
