Part A Microeconomics Chapter 3 Production and Costs VBQ Questions Class 12 Economics with Answers

Question. In the short run Total Product Price changes with the change in which of the following factors.
1. Economic Cost
2. Fixed Cost
3. All the factors
4. Variable Cost
Answer: Variable Cost

Question. How is Total Physical Product derived from Marginal Physical Product?

3. Cumulative product
4. Cumulative Division
Answer: Cumulative addition

Question. Production function shows a technical relationship between physical input and output of a commodity.
1. A technological relationship between inputs and cost
2. The economic relationship between inputs and cost
3. A technological relationship between inputs and output
4. A technological relationship between inputs and price
Answer: A technological relationship between inputs and output

Question. Does Total Physical Product increase only when Marginal Physical Product increases?
Answer: False, because Total Physical Product increases Marginal Physical Product decreases but remains positive.

Question. Increase in Total Physical Product indicates that there are increasing returns to a factor.
Answer: No, the total physical product also rises when the returns to a factor decrease.

Question. Evaluate the marginal product for the following.

Variable Factor Unit0123456
Total Unit051323282824

Answer: 

Marginal Product0581050-4

 

Question. What is a change in quantity demanded?
Answer: It is a change along a demand curve. The change is due to a change in price and quantity of a commodity. The two types of change in quantity demand are Extension in demand and Contraction in demand.

Question. Explain the relation between Average Cost and Marginal Cost.
Answer: The relation between Average Cost and Marginal Cost
• When Average Cost decreases, Marginal Cost declines faster than the Average Cost. So, that Marginal Cost curve remains lower than the Average Cost curve. This means Average Cost > Marginal Cost.
• When Average Cost increases, Marginal Cost rises faster than the Average Cost. SO, that MC curve is above the Average Cost curve
• Marginal Cost curve intersects Average Cost curve from its lowest point. When the average curve is minimum then Marginal Cost = Average Cost.

Very Short Answer Type Questions

Answer: 

CBSE Class 12 Economics Production and Costs VBQs

Question. What effect does an increase in excise tax have on the supply curve?

Question. When is TPP maximum in relation to MPP?
Answer: When MPP is zero.

Question. How does fall in MPP affect TPP?
Answer: TPP increases at decreasing rate.

Question. Why does average cost fall as output rises?
Answer: AC falls due to operation of the law of increasing returns to a factor as output rises.

Question. What would be the effect of increase in the output on the TFC?
Answer: There would not be any effect of increase in the output on the TFC, It will be constant at different levels of production.

Question. What is the price elasticity of supply of a commodity whose straight line supply curve passes through the origin forming an angle of 75º?
Answer: Price elasticity of supply will be equal to one when a straight line supply curve passes through the origin; angle does not matter anything.

Question. What do you mean by production?
Answer: Production is the method of producing or developing goods or services in large quantities with the help of various materials.

Question. When the returns to a factor decline the marginal and the total product also decline.
Answer: False, when returns to a factor decline only Marginal Physical Product declines.

Question. Why Average Fixed Cost curve never touches “x” axis though lies very close to the x-axis?
Answer: The Average Fixed Cost curve never touches “x” axis though lies very close to the x-axis because Total Fixed Cost can never be zero.

Question. When TVC is zero at zero levels of output, what happens to TFC or why TFC is not zero at zero level od output?
Answer: When TVC is zero at zero levels of output, what happens to TFC or why TFC is not zero at zero levels of output because the fixed cost is to be acquired even at zero levels of output.

Question. Define cost concept. What are the different types of cost?
Answer: The spending experienced on different inputs is known as the cost.
Types of cost
• Money Cost- Total money spent by a company for manufacturing goods.
• Explicit Cost & Implicit Cost- Payment made to an outsider are explicit and self-supplied are implicit cost.
• Real Cost- All hard work, discomforts, sacrifices involved in manufacturing a product is called real cost.
• Opportunity Cost- This the cost for the next best alternative foregone.
• Short Run Cost- Fixed cost- Fixed factors cost Variable Cost– Variable factor cost

Question. Why does average fixed cost fall with increase in output?
Answer: AFC can be calculated from TFC. Which remains constant at all level of output.

Question. Under which situation will MR fall when an additional quantity of a good is sold?
Answer: When per unit price falls by selling an additional unit of a good.

Question. Give one differences between law of supply and price elasticity of supply.
Answer: Law of supply reflects the direction of change in supply where as price elasticity of supply measures the magnitude of change in supply.

Question. Why does a producer moves downward along a supply curve due to decrease in price of commodity?
Answer: Because profit margin of firm (producer) decreases.
