Take a brand study its price elasticity of demand and relate it to revenue. Say how the REVENUE of the product increases or decreases because of the ELASTICITY. The elasticity of demand measures the responsiveness of the quantity demanded of a good, to change in its price, price of other goods and change in consumer’s income. Accordingly elasticity of demand is of three types:

Price elasticity of demand
Income elasticity of demand
Cross elasticity of demand
Price elasticity of demand: it is the ratio of the percentage change in quantity demand of a commodity to the percentage change in its price. Price elasticity of demand denotes the ratio at which the demand contracts with a rise in price and extends with a fall in price. Ed=(percentage change in quantity demanded)/(percentage change in price)

Ed=ΔQ/ΔP×P/Q; where P=price; Q= quantity demanded.

Price elasticity of demand is of five types:
Perfectly inelastic(Ed=0)
Perfectly elastic(Ed=∞)
Relatively inelastic(Ed1)
Unitary elastic(Ed=1)

It is a brand of chocolate bar made by the Cadbury plc unit of Kraft foods. It first started sales in UK in the year 1905 and thereby came to India in the year 1948.
