Class 12 Micro Economics - Chapter Production and Costs NCERT Solutions | What is the marginal product of an input

What is the total product of input?

Explain the relationship between the marginal products and the total product of an input.

The following table gives the total product schedule of labour. Find the corresponding average product and marginal product schedules of labour.

What is the law of diminishing marginal product? 

What do the long-run marginal cost and the average cost curves look like? 

What are the average fixed cost, average variable cost and average cost of a firm? How are they related? 

Briefly explain the concept of the cost function. 

What does the average fixed cost curve look like? Why does it look so?
