You can prove the same with the numerical example....
P1 = 10......S1= 100,000................therefore revenue =1,000,000
P2 = 12.....S2 = 83,333........... ......therefore revenue = 1,000,000
P3 = 9........S3 = 111,111................therefore revenue = 1,000,000
In this example the PRICE elasticity of DEMAND is perfectly inelastic.
If PED (Price Elasticity of Demand) is less than 1......it is inelastic
If PED is zero....it is perfect inelastic
If PED is greater than 1 ........it is elastic
If PED is infinite........ it is perfect elastic
