From the above schedule, it is clear that at price Rs.4, the market demand is equal to market supply of 20 units. Hence at Rs.4, the market is in equilibrium. For market price to remain unchanged or constant, increase in demand should be exactly equal to increase in supply. In the above schedule, 100 per cent increase in both demand and supply causes no change in market price. Therefore, new equilibrium is also stuck at a price Rs.4 per unit.
