THE THEORY OF THE FIRM MCQs

Total Questions : 25 | Page 1 of 3 pages
Question 1. The slope of the TC curve gives
  1.    MC
  2.    SAC
  3.    AVC
  4.    0
 Discuss Question
Answer: Option A. -> MC
:
A
The slope of the TC curve = ΔTC/Δq
= MC
Question 2. If we multiply the x and y coordinates of any point on the AFC curve, we get
  1.    TVC
  2.    ATC
  3.    TFC
  4.    1
 Discuss Question
Answer: Option C. -> TFC
:
C
If we multiply the x and y coordinates of any point on the AFC curve, we get TFC since
AFC x q = TFC
Question 3. For a firm operating in a perfectly competitive market, the slope of the TR curve is
  1.    increasing
  2.    decreasing
  3.    constant
  4.    zero
 Discuss Question
Answer: Option C. -> constant
:
C
For a firm operating in a perfectly competitive market, the slope of the TR curve is equal to the price and is constant.
Question 4. The efficient scale of production is the quantity of output that minimizes the ___ .
  1.    Average fixed cost
  2.    Average total cost
  3.    Average variable cost
  4.    Marginal Cost
 Discuss Question
Answer: Option B. -> Average total cost
:
B
The efficient scale of production is the quantity of output that minimizes the average total cost.
Question 5. What is the average product of the first three hours of labour?
HoursMP01100280360
  1.    60
  2.    80
  3.    100
  4.    240
 Discuss Question
Answer: Option B. -> 80
:
B
TP = sum of all MPs
=100+80+60 = 240
AP for three hours = TP/3
= 240/3 =80
Question 6. What is the shape of the AFC curve?
  1.    Parabola
  2.    Straight line
  3.    Rectangular hyperbola
  4.    U-shaped
 Discuss Question
Answer: Option C. -> Rectangular hyperbola
:
C
Shape of the AFC curve is a rectangular hyperbola.
Question 7. Which of the following pairs of curves start from the same point?
  1.    AVC and AFC
  2.    SAC and AVC
  3.    SAC and SMC
  4.    AVC and SMC
 Discuss Question
Answer: Option D. -> AVC and SMC
:
D
For the first unit of output, SMC =AVC. Hence these two curves start from the same point.
Question 8. The numbers of units produced by a firm and the corresponding costs are tabulated below.
No. of unitsTotal cost100Rs 2000250Rs 3500
Assuming constant variable cost per unit, calculate the AFC for 100 units.
  1.    Rs 10
  2.    Rs 20
  3.    Rs 100
  4.    Rs 1000
 Discuss Question
Answer: Option A. -> Rs 10
:
A
Let the fixed cost be F and the variable cost per unit be v.
F +100 v = Rs 2000
F + 250 v = Rs 3500
On solving, we get F = 1000 =TFC and v = 10 = AVC
Now, AFC = TFC / 10 = 1000/100 = Rs 10
Question 9. The profit of a firm is given by ___
  1.    (P−SAC)×q
  2.    (SAC−P)×q
  3.    (P−AVC)×q
  4.    (AVC−P)×q
 Discuss Question
Answer: Option A. -> (P−SAC)×q
:
A
The profit of a firm is given by (PSAC)×q
Question 10. The slope of the TFC curve is equal to 
  1.    AFC
  2.    1
  3.    -1
  4.    0
 Discuss Question
Answer: Option D. -> 0
:
D
Slope of TFC curve = 0 since TFC is a constant. TFC curve is a straight line parallel to the x-axis.
