Explain the law of variable proportions with the help of total product

1.	Explain the law of variable proportions with the help of total product curve. Use diagram.
Answer» Solution :According to the Law of VARIABLE Proportions as only one input is increased, other remaining unchanged, the total product increases at an increasing rate, then at a DECREASING rate and ultimately falls. Phase I In the first phase, TP increases at an increasing rate upto point A. Phase II In the second phase. TP increases at a DIMINISHING rate between point A & B Phase III In the third phase, TP starts falling beyond point B.
