(a)

Price (Rs.)Qty (Uts)Total expenditure
20801600
161001600

Here total expenditure remains constant, Elasticity of demand is equal to units, i.e. 

ep= 1

(b) Two exceptions of law of demand: 

1. Ignorance: Sometimes people buy more of a commodity at a higher price merely because they consider the commodity to be superior. If the price is low, people think the commodity to be of poor quality and may not like to buy it. 

2. Change in fashion or taste: The law does not apply if there is a change in fashion or taste. If a commodity, goes out of fashion, it may not be demanded even at a lower price.

(c) Individual Supply Schedule for Apples

Price (Rs./kg)Qty. Supplied (Kgs)
102
204
306
408
5010

supply curve
