Answer #1

7.

Q=5KL2

If K=10 fixed

Q=5*10 L2

Q=50 L2

Hence short-run production function will be

Q=50 L2

Hence option d is the correct answer.

8.

If total cost function is linear

For example

TC=a+bQ

Here a and b are constant.

MC=dTC/dQ

=0+b

=b

AVC=TVC/Q

=bQ/Q

=b

It means both MC and AVC will be equal.

Hence option b is the correct answer.

9.

Since the slope of isoquant is Marginal rate of technical substitution (MRTS) and it is calculated as= MPL/MPK

Hence it can be said that marginal rate of technical substitution is the absolute slope of the isoquant.

Hence option d is the correct answer.

10.

Since with the decrease in the variable inputs price will leads to decrease in total variable cost as well as average variable cost. so AVC curve will shift downward.

Since this is not given in the option.

Hence option e is the correct answer.
