Question of 29

Q.From following table, draw the diagram of determination of equilibrium price under perfect competition-
Price (₹ per Unit): 1, 5, 8, 10, 20
Demand (Units): 100, 60, 50, 30, 10
Supply (Units): 10, 40, 50, 60, 100

From the given schedule, demand equals supply (both = 50 units) at price ₹8 — that is the equilibrium point.

Tabulate the data:

Price (₹): 1, 5, 8, 10, 20

Demand (units): 100, 60, 50, 30, 10

Supply (units): 10, 40, 50, 60, 100

At ₹1, demand (100) far exceeds supply (10) — excess demand of 90 units pushes price up. At ₹5, demand (60) still exceeds supply (40) — excess demand of 20 units, price keeps rising. At ₹8, demand (50) exactly equals supply (50) — no excess demand or supply, so price has no further tendency to change: this is the equilibrium. At ₹10, supply (60) exceeds demand (30) — excess supply of 30 pushes price back down. At ₹20, supply (100) far exceeds demand (10) — a large excess supply, price falls further.
