Market equilibrium occurs where the market demand curve and the market supply curve intersect — the price at which quantity demanded exactly equals quantity supplied.

Table (hypothetical figures):

Price (₹)Market Quantity Demanded (units)Market Quantity Supplied (units)Pressure on Price
1010020Excess demand → price rises
208040Excess demand → price rises
306060Equilibrium (QD = QS)
404080Excess supply → price falls
5020100Excess 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.
