Question 2: Distinguish between cardinal and ordinal utility. (2 marks) Answer:
| Cardinal Utility | Ordinal Utility |
|---|---|
| Utility can be measured in absolute terms (utils) | Utility can only be ranked or ordered |
| Assumes utility is quantifiable | Assumes utility is subjective and cannot be measured |

| Based on cardinal numbers (1, 2, 3, etc.) | Based on ordinal numbers (1st, 2nd, 3rd, etc.) |
| Interpersonal comparison of utility is possible | Interpersonal comparison of utility is not possible |
Question 3: Explain the law of demand with its exceptions. (5 marks) Answer: The law of demand states that there is an inverse relationship between the price of a commodity and its quantity demanded, other factors remaining constant.
Explanation:
- When price increases, quantity demanded decreases
- When price decreases, quantity demanded increases
- This relationship is represented by a downward-sloping demand curve
- The law operates due to income effect, substitution effect, and diminishing marginal utility
Exceptions to the law of demand:
- Giffen goods: Inferior goods with strong income effect that outweighs substitution effect (e.g., low-quality food items for very poor people)
- Veblen goods: Goods purchased for their snob appeal or prestige value (e.g., luxury goods, diamonds)
- Expectation of future price changes: If prices are expected to rise further, people may buy more at higher prices
- Necessities: Essential goods like medicines are purchased regardless of price increases
- Ignorance and habit: Consumers may be unaware of price increases or might continue buying out of habit
- Emergency situations: During crises, people buy necessities regardless of price
- Bandwagon effect: Desire to conform with majority leads to increased demand despite price rise

3. March 2022 Economics Question Paper with Answers
Question 1: What is the significance of statistics in economics? (1 mark) Answer: Statistics in economics helps in collecting, organizing, analyzing, and interpreting numerical data to identify patterns, establish relationships between economic variables, test economic theories, forecast trends, and formulate effective economic policies.
Question 2: Discuss the properties of indifference curves. (3 marks) Answer: Properties of Indifference Curves:
- Indifference curves slope downward from left to right:
- Negative slope indicates that to increase consumption of one good, some amount of the other good must be sacrificed
- Based on the assumption that both commodities are desirable
- Indifference curves are convex to the origin:
- Reflects diminishing marginal rate of substitution
- As more of one good is acquired, consumer is willing to give up less of the other
- Higher indifference curves represent higher levels of satisfaction:
- Curves further from the origin indicate higher utility
- Consumer prefers points on higher indifference curves
- Indifference curves cannot intersect:
- Intersection would violate the assumption of consistent consumer preferences
- Same point cannot represent two different levels of satisfaction
- Indifference curves are thick sets:
- Infinite number of curves can be drawn between any two commodities
- Each curve represents a specific level of satisfaction
- Indifference curves cannot touch either axis:
- Based on assumption that consumer always prefers some combination of both goods
- Complete elimination of one good would reduce utility drastically
Question 3: Explain the law of variable proportions with suitable diagram. (5 marks) Answer: The law of variable proportions states that when the quantity of one factor is increased while all other factors are held constant, the total product initially increases at an increasing rate, then increases at a decreasing rate, and finally starts decreasing.
Stages of the Law:
- Stage I – Increasing Returns:
- Marginal product (MP) increases and is greater than average product (AP)
- AP also increases
- Specialization and efficient utilization of fixed factors
- Ends when MP reaches its maximum
- Stage II – Diminishing Returns:
- MP starts decreasing but remains positive
- AP first increases, reaches maximum, then starts decreasing
- Optimum utilization of fixed factors
- Ends when MP becomes zero
- Stage III – Negative Returns:
- MP becomes negative
- TP starts decreasing
- Over-utilization of fixed factors
- Irrational stage of production
Diagram: [A graph showing Total Product (TP), Average Product (AP), and Marginal Product (MP) curves. TP rises at increasing rate, then at decreasing rate, and finally decreases. AP rises, reaches maximum, then falls. MP rises, reaches maximum before AP, then falls, crosses x-axis and becomes negative.]
Significance:
- Helps determine optimal combination of fixed and variable factors
- Explains the stage in which production should operate (Stage II)
- Demonstrates importance of proportional factor utilization
- Forms basis for returns to scale concept
- Provides foundation for cost curves

(1 mark) Answer: The basic characteristics of Indian economy include mixed economy structure, co-existence of public and private sectors, low per capita income, dependence on agriculture, demographic diversity, and persistent economic inequalities.
Question 2: Explain the law of diminishing marginal utility with suitable diagram. (3 marks) Answer: The law of diminishing marginal utility states that as a consumer consumes more and more units of a commodity, the utility derived from each additional unit goes on diminishing, assuming that consumption of all other commodities remains constant.
Explanation:
- First few units provide high satisfaction
- As consumption increases, additional satisfaction decreases
- Eventually additional units might provide zero or negative utility
- Based on psychological fact that wants are satiable
Assumptions:
- Homogeneous units of the commodity
- Continuous consumption
- No change in consumer tastes or preferences
- No change in price of the commodity
- No change in consumer’s income
- No time gap between consumption of units
Diagram: [A graph showing Total Utility (TU) and Marginal Utility (MU) curves. TU increases at decreasing rate and eventually reaches maximum. MU consistently decreases and eventually becomes negative.]

Determination of Equilibrium Price:
- Market forces of demand and supply interact
- At equilibrium point, demand equals supply
- No tendency for price to change
- Stable market situation
Diagram: [A graph showing demand and supply curves intersecting at point E. The equilibrium price is P* and equilibrium quantity is Q*.]
Mathematical Representation: If demand function is Qd = a – bP And supply function is Qs = c + dP At equilibrium: Qd = Qs Therefore: a – bP = c + dP Solving for P: P* = (a – c)/(b + d)
Effects of Changes in Demand and Supply:

Question 3: Define elasticity of demand. Explain the methods of measuring price elasticity of demand. (5 marks) Answer: Elasticity of Demand: Price elasticity of demand is the degree of responsiveness of quantity demanded of a commodity to a change in its price. Mathematically, it is the percentage change in quantity demanded divided by the percentage change in price.
Formula: Ed = (Percentage change in quantity demanded) / (Percentage change in price)
Methods of Measuring Price Elasticity of Demand:
- Percentage Method:
- Formula: Ed = (ΔQ/Q) ÷ (ΔP/P) = (ΔQ/ΔP) × (P/Q)
- ΔQ = Change in quantity, Q = Original quantity
- ΔP = Change in price, P = Original price
- Simple and widely used method
- Example: If price increases by 10% and quantity decreases by 20%, Ed = 20%/10% = 2
- Point Method (Point Elasticity):
- Used for infinitesimal changes in price
- Formula: Ed = (dQ/dP) × (P/Q)
- Where dQ/dP is the derivative of demand function
- Used in continuous demand functions
- Measures elasticity at a specific point on demand curve
- Arc Method (Arc Elasticity):
- Measures elasticity over a range of the demand curve
- Formula: Ed = (Q₂-Q₁)/(Q₂+Q₁) ÷ (P₂-P₁)/(P₂+P₁)
- Uses average of two prices and quantities
- More accurate for larger price changes
- Example: If P₁=10, P₂=12, Q₁=50, Q₂=40, then: Ed = (40-50)/(40+50) ÷ (12-10)/(12+10) = (-10/90) ÷ (2/22) = -1.22
- Total Expenditure Method:
- Based on relationship between price and total expenditure
- Total expenditure = Price × Quantity
- If price increases and total expenditure increases: Ed < 1 (inelastic)
- If price increases and total expenditure decreases: Ed > 1 (elastic)
- If price increases and total expenditure remains constant: Ed = 1 (unitary elastic)
- Simple but less precise method
- Geometric Method:
- At any point on demand curve, elasticity = Lower segment/Upper segment
- At midpoint of straight line demand curve, Ed = 1
- At upper end of demand curve, Ed = ∞
- At lower end of demand curve, Ed = 0
- Useful for linear demand curves
Factors Affecting Price Elasticity:
- Nature of commodity (necessity vs. luxury)
- Availability of substitutes
- Proportion of income spent
- Number of uses
- Time period
- Habit formation
- Postponement of consumption

Question 3: Explain the concept of consumer’s equilibrium using indifference curve analysis. (5 marks) Answer: Consumer’s Equilibrium using Indifference Curve Analysis:
Consumer’s equilibrium refers to the situation where a consumer maximizes satisfaction from spending income on different goods, given market prices and budget constraints.
- Basic Components:
- Indifference Map: Set of indifference curves showing consumer preferences
- Budget Line: Shows all possible combinations of goods that can be purchased with given income and prices
- Equilibrium Point: Point where budget line is tangent to the highest possible indifference curve
- Mathematical Representation:
- At equilibrium: MRSxy = Px/Py
- MRSxy = Marginal Rate of Substitution between goods X and Y
- Px/Py = Ratio of prices of goods X and Y
- This represents equality between subjective rate (MRS) and objective rate (price ratio)
- Graphical Representation: [A graph showing multiple indifference curves with a budget line tangent to one of them at point E. The budget line connects points on X and Y axes representing maximum purchasable quantities of each good alone.]
- Conditions for Consumer’s Equilibrium:
- First-order condition: MRSxy = Px/Py
- Second-order condition: Indifference curve must be convex to origin at point of tangency
- Budget constraint must be satisfied: PxQx + PyQy = Income
- Properties of Equilibrium:
- Unique solution under normal assumptions
- Stable equilibrium as consumer has no incentive to move
- Maximizes utility for given budget constraint
- Satisfies both necessary and sufficient conditions
- Changes in Equilibrium:
- Income Effect: Change in real income shifts budget line parallel
- Substitution Effect: Change in relative prices rotates budget line
- Price Effect: Combination of income and substitution effects
Advantages of Indifference Curve Analysis:
- Avoids cardinal measurement of utility
- Accounts for diminishing marginal rate of substitution
- Accommodates both inferior and normal goods
- Integrates income and substitution effects
- Provides clear geometric representation
