Assertion (A): In case of perfectly inelastic supply, supply curve is a vertical straight line supply curve.

Reason (R): Supply does not change with change in price in case of Es = 0.

Define elasticity of supply.

When is the supply of a commodity is called elastic?

Draw a straight line supply showing elasticity greater than one.

Price of a product increases by 2%. As a result, its supply rises by 4%. What is elasticity of supply of the commodity?

The coefficient of elasticity of a commodity is 0.4. What percentage change in supply will take place if its price rises 20%?

With the help of a formula calculate the elasticity of supply from the following table:
