This document provides an overview of consumer equilibrium using both the utility and indifference curve approaches. It defines key concepts like total utility, marginal utility, indifference curves, and budget lines. It explains that in the utility approach, consumer equilibrium occurs when the marginal utility per rupee is equal for all goods. In the indifference curve approach, equilibrium is reached at the point where the budget line is tangent to the highest attainable indifference curve, meaning the slope of the indifference curve equals the slope of the budget line. The document also discusses how changes in prices and income affect the budget line and consumer equilibrium.
