Part – B

Answer the following questions in one or two sentences

Question 1.
Give the definition for Economic Cost?
Answer:

1.    Economic cost refers to all payments made to the resources owned and purchased or hired by the firm in order to ensure their regular supply to the process of production. It is the summation of explicit and implicit costs.

2.    Economic Cost is relevant to calculate the normal profit and thereby the economic profit of a firm.

Question 2.
What is the economic cost?
The economic cost is the summation of explicit and implicit costs.

Question 3.
What is the Average Variable Cost?
Answer:
The average variable cost refers to the total variable cost per unit of output. It is obtained by dividing total variable cost (TVC) by the quantity of output [Q], AVC = TVC/Q, where AVC denotes Average variable cost, TVC denotes total variable cost and Q denotes the quantity of output.

Question 4.
What is a floating cost?
Answer:
Floating cost refers to all expenses that are directly associated with business activities but not with asset creation.

Question 5.
What are variable costs?
Answer:
Variable cost vary with the level of output. It is also called as prime cost, special cost or direct cost.

Question 6.
What is total revenue?
Answer:
Total revenue is the amount of income received by the firm from the sale of its products.

Question 7.
What is marginal revenue?
Answer:
Marginal revenue is the addition to the total revenue by the sale of an additional unit of a commodity.
MR = TR_n – TR_n-1

Part – C

Answer the following questions in One Paragraph

Question 1.
How can you calculate average fixed cost ?
Answer:
Average fixed cost is the fixed cost per unit of output. It is obtained by dividing the total fixed cost by the quantity of output.
AFC = TFCQ
(Eg.) If TFC is 100;
Q = 10 Find AFC
AFC = TFCQ
= 100010
AFC = 100.

Question 2.
Define the Prime Cost?
Answer:

1.    All costs that vary with output, together with the cost of administration are known as Prime Cost.

2.    Prime Cost = Variable Costs + Costs of Administration.

Question 3.
Write a note on average revenue.
Answer:
Average revenue is the revenue per unit of the commodity sold. It is calculated by dividing the total revenue (TR) by the number of units sold (Q).
AR = TRQ
If TR = PQ
AR = PQQ = P
AR = P
AR – Average revenue, TR – Total revenue, Q – quantity of unit sold.
