Fundamental Concepts Utility: The want-satisfying power of a commodity. consumer equilibrium class 11 notes free

• Formula: $MU_n = TU_n - TU_n-1$

6. Quick Revision Points (For Exams)

1. Assumptions: Rational consumer, fixed income, fixed prices, cardinal measurement of utility (for MU analysis).
2. Equilibrium: A state of balance with no tendency to change.
3. Law of DMU: Fundamental basis for determining equilibrium price.
4. Diagram: Always draw a neat labeled diagram (IC tangent to Budget Line) for the Indifference Curve approach.

• Buy 1st Chai (₹5 left ₹45). MU/Price: Samosa=3, Chai=3? No, after 1 chai, chai's MU/price falls to 3 (15/5). Now both equal.
• Buy 1st Samosa (₹10, left ₹35). Now check again: Next samosa MU/price = 2, next chai MU/price = 2.
• Buy 2nd Chai (₹5, left ₹30).
• Buy 2nd Samosa (₹10, left ₹20).
• Buy 3rd Chai (₹5, left ₹15).

Numerical Example (Price of Apple = ₹5)

| Units of Apple | MU (utils) | Price (₹) | Decision | | :--- | :--- | :--- | :--- | | 1 | 10 | 5 | MU > P → Buy | | 2 | 8 | 5 | MU > P → Buy | | 3 | 5 | 5 | MU = P → STOP (Equilibrium) | | 4 | 2 | 5 | MU < P → Don’t buy | Consumer equilibrium is a state where a consumer
