Class 11 Microeconomics Half-Yearly Important Questions

These Class 11 Economics half-yearly important questions cover key concepts from Microeconomics. They include questions on economic problems, opportunity cost, consumer equilibrium, demand and production.

1. What are the causes of the economic problem?

Answer: The economic problem arises because:

1. Human wants are unlimited.

2. Resources are limited.

3. Resources have alternative uses.

2. Explain the concept of opportunity cost with an example.

Answer: Opportunity cost refers to the value of the second-best alternative that is given up.

For example, if a person has two job options, one offering Rs. 10,000 and another offering Rs. 9,000, choosing the Rs. 10,000 job means Rs. 9,000 is the opportunity cost.

3. Explain the problems of what to produce, how to produce and for whom to produce.

Answer:

• What to produce: It refers to deciding which goods should be produced in an economy and in what quantity.

• How to produce: It refers to choosing the production technique. The two techniques are labour-intensive and capital-intensive technology.

• For whom to produce: It is related to the distribution of income and the choice between social equality and economic growth.

4. What is the relationship between MU and TU?

Answer:

• When MU is falling but positive, TU increases.

• When MU is zero, TU becomes maximum.

• When MU becomes negative, TU starts falling.

5. Explain consumer equilibrium in the case of a single commodity.

Answer: Consumer equilibrium is a situation where a consumer maximises total utility from a given income.

The conditions are:

1. MU must be falling.

2. The consumer should reach the condition where the marginal utility of the commodity is equal to the marginal utility of money multiplied by its price.

6. Explain the three properties of indifference curves.

Answer:

1. Downward sloping: An indifference curve slopes downward because consuming more of one good requires giving up some quantity of the other good to maintain the same satisfaction.

2. Convex to the origin: It is convex because of diminishing marginal rate of substitution.

3. Higher indifference curve: A higher indifference curve represents a higher level of utility.

7. What are the factors affecting demand of a commodity?

Answer: The important factors include:

• Price of the commodity

• Taste and preferences

• Income of the buyer

• Number of consumers

• Price of related goods

• Expectations about future prices

8. Differentiate between change in quantity demanded and change in demand.

Answer:

9. Explain the factors affecting price elasticity of demand.

Answer: The factors include:

• Nature of the commodity

• Availability of close substitutes

• Number of uses

• Habit

• Share in total expenditure

• Level of income

• Possibility of postponing use

10. State the relationship between MP and TP.

Answer:

• When MP rises, TP increases at an increasing rate.

• When MP starts falling but remains positive, TP increases at a decreasing rate.

• When MP is zero, TP is maximum.

• When MP becomes negative, TP starts falling.

11. Explain the law of variable proportion.

Answer: The law states that when more units of a variable factor are used with a fixed factor, total product first increases at an increasing rate, then at a decreasing rate and finally starts falling.

The law has three phases:

1. Increasing returns: TP increases at an increasing rate and MP also rises.

2. Diminishing returns: TP increases at a decreasing rate and MP falls but remains positive.

3. Negative returns: TP starts falling and MP becomes negative.

Class 11 Statistics Important Questions 

Statistics is an important part of Class 11 Economics. The following questions cover key concepts such as the importance and limitations of statistics, types of data and classification of data.

These questions can help students revise the main Statistics concepts and prepare for different types of questions in the half-yearly exam.

1. What is the importance of statistics in economics?

Answer: Statistics helps in:

• Making economic laws.

• Finding mathematical relationships between variables.

• Studying market structure.

• Economic planning and forecasting.

• Business decision-making related to costs, demand, prices and sales.

2. Explain the limitations of statistics.

Answer: The main limitations are:

1. Statistics studies only numerical facts.

2. It studies aggregates rather than individual units.

3. Data should be homogeneous for comparison.

4. Statistical results are generally true only on an average.

3. Differentiate between primary and secondary data.

Answer:

Primary data is collected directly by the person using it. It takes more time to collect but is more accurate.

Secondary data is not originally collected by the person using it. Its collection takes less time but it is comparatively less accurate.

4. Explain the different methods of classification of data.

Answer: The main methods are:

• Chronological classification: Data is arranged according to time.

• Geographical classification: Data is classified according to place.

• Qualitative classification: Data is classified using descriptive characteristics.

• Quantitative classification: Data is classified using measurable characteristics.

• Conditional classification: Data is classified according to a condition.

5. Explain the essential properties of arithmetic mean.

Answer:

1. The sum of deviations of observations from the mean is zero.

2. The sum of squared deviations from the mean is minimum compared with other central values.

3. If every observation is replaced by the mean, the total remains equal to the sum of the original observations.
