Suppose the price of Maggi falls down to Rs.120 from Rs.210. As a result, the budget line shifts to AC and indifference curve to IC1. Hence, the consumer equilibrium point shifts to F. At this point, the consumer is getting maximum satisfaction by spending Rs.480 on 4 units of Maggi and Rs 360 on 18 units of Noodles. Hence, consumers consumption of Maggi increases and quantity demanded of Noodles decreases with a fall in the price of Maggi.
