Fall in Prices of the Related Goods: Related goods may be complementary or supplementary.
In Case of Substitute Goods: Let “A” and “B” are substitutes. If the price of the good “A” falls, then the consumer will shift their preference towards that good “A”. As a result, the demand for the good “B” decreases. Ex. If the price of tea falls, then the supply of coffee will fall.
In Case of Complementary Goods: Suppose “M” and “N” is complementary goods. If the price of the goods “M” falls, then the consumer will shift their preference towards its complementary good “N”. This will lead to increase in the demand of the good “N.
Define an indifference curve. Explain why an indifference curve is downward sloping from left to right.
When price of good is Rs 7 per unit a consumer buys 12 units. When price falls to Rs6 per unit he spends Rs 72 on the good. Calculate price elasticity of demand by using the percentage method. Comment on the likely shape of demand curve based on this measure of elasticity.

Explain the conditions of a producer’s equilibrium in terms of marginal cost and marginal revenue. Use diagram.
Market for a good is in equilibrium. There is simultaneous increase both in demand and supply of the good. Explain its effect on market price.
