Table (hypothetical figures):
| Price (₹) | Market Quantity Demanded (units) | Market Quantity Supplied (units) | Pressure on Price |
|---|---|---|---|
| 10 | 100 | 20 | Excess demand → price rises |
| 20 | 80 | 40 | Excess demand → price rises |
| 30 | 60 | 60 | Equilibrium (QD = QS) |
| 40 | 40 | 80 | Excess supply → price falls |
| 50 | 20 | 100 | Excess supply → price falls |
Explanation: The market demand curve (downward sloping) shows the total quantity all buyers are willing to buy at each price; the market supply curve (upward sloping) shows the total quantity all sellers are willing to sell at each price. At prices below equilibrium (e.g., ₹10 or ₹20 above), quantity demanded exceeds quantity supplied, creating excess demand, which pushes the price up. At prices above equilibrium (e.g., ₹40 or ₹50 above), quantity supplied exceeds quantity demanded, creating excess supply, which pushes the price down. Only at ₹30 (in this example), where quantity demanded equals quantity supplied (60 units each), is there no further tendency for price to change — this is the market equilibrium price, and 60 units is the equilibrium quantity.
