# In case of law of variable proportions, point of inflexion is where: •

A. TP starts declining because MP is negative.

B. TP stops increasing at the increasing rate and starts increasing at the decreasing rate.

C. MP is decreasing and TP is increasing at the increasing rate.

D. MP is increasing and TP is increasing at the increasing rate.

### Right Answer is: B

#### SOLUTION

• **The Law of Variable Proportions is also known as the Law of Proportionality.**

• The law explains the production function with one-factor variable, keeping other factors as fixed.

• In the case of the law of variable proportions, the point of inflexion is where Total Product stops increasing at the increasing rate and starts increasing at the decreasing rate.
