Question

law of variable proportion is valid when​

Answer 1

Answer:

The law of variable proportions is as follows: “If a producer increases the units of a variable factor while keeping other factors fixed, then initially the total product increases at an increasing rate, then it increases at a diminishing rate, and finally starts declining.”

Answer 2

Answer:

The law of variable proportions is universal as it applies to all fields of production.

This law applies to any field of production where some factors are fixed and others are variable.

That is why it is called the law of universal application. The main cause of application of this law is the fixity of any one factor.
