Inside fig, X-axis suggests the quantity of Maggi needed while Y-axis suggests the amount of the other item (Noodles) demanded. Here, Ab ‘s the fresh funds range and you may IC ‘s the brand-new Apathy bend. E is the balance point in which budget line Ab try tangent for the IC contour. Up until now, an individual gets restriction satisfaction from the using his money of Rs.840 ( Rs.420 toward dos products away from Maggi and Rs.420 toward 2step one gadgets regarding Spaghetti). 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. Similarly, When the price of Maggie again, reduced to Rs.70, the budget line and indifference curve shifts to AD and IC2. As a result, the equilibrium point shifts to F where budget line AD is tangent to indifference curve IC2. At this point, the consumer is spending Rs560 on 8 units of Maggi and Rs.280 on 14 units of Noodles to get maximum satisfaction.What is the Rates Use Curve :
