Sample Paper 2014-15 & 15-16 & 16-17

(Q1) If it is given that the total variable cost for producing 15 units of output is Rs. 3000 and for 16 units is Rs. 3,500. Find the value of Marginal Cost.

Ans: 500

(Q2) If a firm’s production department data says that the total variable cost for producing 8 units and 10 units of output is 2,500 and 3,000 respectively, marginal cost of 10th unit will be

a. 100 b. 150 c. 500 d. 250

Ans:  (d) 250

(Q3) The total cost at 5 units of output is Rs 30. The fixed cost is Rs 5. The average variable cost at 5 units of output is :

(a) Rs 25 (b) Rs 6 (c) Rs 5 (d)  Re 1

Ans: (c)

(Q4) State true or false 

(a)  AFC curve is a rectangular hyperbola curve.

(b)  Total cost rises only when marginal cost rises

(c) With increase in level of output, average fixed cost goes on falling till it reaches zero.

Ans: 

(a) True : Since TFC remains unchanged / constant.

(b) False : Total cost rises at a diminishing rate when marginal cost falls and total cost rises at an increasing rate when marginal cost increases.

(c) False :  TFC is constant and positive. So with an increase in output AFC will fall but can never be zero.

(Q5) Justify the statement, ‘In economics, normal profits are always a part of total cost’. (3)

Ans: The given statement is correct .

Normal profit is defined as the minimum reward that is just sufficient to keep the entrepreneur supplying his factor service  Since total cost includes payment made to primary inputs: land, labour, capital andenterprise, total cost includes rent, wages, interest and (normal) profits

(Q6) Find out (a) explicit cost and (b) implicit cost from the following :(4 marks)

Ans. 400, 400

C.B.S.E Paper 2014


(Q1) Define variable cost.  (1 mark)

Ans: The cost which changes with change in output is called variable cost.

(Q2) What is cost in economics ?  (1 mark)

Ans: Cost in economics refers to the sum of actual money expenditure on inputs and the estimated value of the free inputs supplied by the owner.

(Q3) Draw a total variable cost curve and a total cost curve in a single diagram.(3M)

(Q4) Explain behaviour of Average Fixed Cost (AFC). Use diagram.(3M)

Ans: AFC falls continuously as output is increased.It is because, even when output is increased TFC remains unchanged.

(Q5) Explain the relation between total Cost and Marginal cost

Ans: W hen TC rises at a decreasing rate, MC falls. When TC rises at an increasing rate MC rises. When TC rises at a constant rate MC is constant

Sample Paper 2015

(Q1) The total cost at 5 units of output is Rs. 30. The fixed cost is Rs. 5. The average variable cost at 5 units of output is :(1 M)

(a) Rs. 25 (b) Rs. 6 (c) Rs. 5 (d) Rs.1

(Q2) State True or False. Justify your answer.(3 M)

(a) Total cost rises only when marginal cost rises.

C.B.S.E Paper 2015

(Q1) What is the behaviour of (a) Average Fixed Cost and (b) Average Variable Cost as more and more units of a good are produced ?(4 M)

Ans:  (a) AFC falls continuously as more and more output is produced. (2M)

(b) AVC falls initially and after a level of output, starts rising as more and more output is produced. (2M)

(Q2) The average fixed cost at 4 units of output is Rs.20. Average variable cost at 5 units of output is Rs.40. Average cost of producing 5 units is :[AI (C)]

(a) Rs.20 (b) Rs.40 (c) Rs. 56 (d) Rs. 60

(Q3) Giving reasons, state whether the following statements are true or false?[AI (C)]

(a) The difference between AC and AVC is always constant. (b) When MC rises, AVC must rise. (c) Average cost will rise only when marginal cost rises. 

(Q4) State the relationship between :[AI (C)]

(a) Marginal cost and average variable cost (b) Total cost and marginal costExplain the

(Q5) Define cost. State the relation between marginal cost and average variable cost.(1M)

Ans: Cost in economics refers to the sum of actual money expenditure on inputs and the imputed expenditure in the form of inputs supplied by the owners including normal profit.

If MC < AVC , then AVC falls

If MC = AVC, then AVC is constant 

If MC > AVC, then AVC rises                      (Diagram not required)

(Q6) The average fixed cost at 4 units of output is Rs 20. Average variable cost at 5 units of output is Rs 40. Average cost of producing 5 units is rupees  : (1)

(a)  20 (b) 40 (c)  56 (d)  60

Ans: (c)

(Q7)Giving reasons, state whether the following statements are true or false : The difference between average cost and average variable cost is always constant

Ans: False, The difference between AC and AVC is due to AFC. As output is increased AFC falls, so the difference between AC and AVC falls.
