QUESTION: 8

The Average fixed cost for producing on output of 6 units of a product by a firm is Rs. 30. The same cost for producing an output of 4 units will be Rs. ______.

Solution:
QUESTION: 9

Which of the following cost curves is never ‘U’ shaped?

Solution:

The total fixed curve is plotted as straight line parallel to the x axis as fixed costs do not change with the level of output produced in the short run.

QUESTION: 10

Marginal cost changes due to change in ________ cost.

Solution:
QUESTION: 11

Average total cost to a firm is Rs. 600 when it produces 10 units of output and Rs 640 when the output is 11 units. The MC of the 11th unit is:

Solution:

At level 10
TC=AC x Q
=600x 10
= 6000
At level 11
TC= 640 x 11
=7040
Now MC = 7040 - 6000
= 1040

QUESTION: 12

Solution:
QUESTION: 15

Suppose the total cost production of a commodity ‘x’ is Rs. 1, 25,000 out of which Implicit cost is Rs. 35,000 and normal profit is Rs. 25,000. What would be the explicit cost of commodity x?

Solution:

125000-25000-35000 = 65000 = explicit cost.
Total cost = implicit cost + explicit cost.
