Question : When marginal utility is negative, total utility is as follows:
Option 1: Starts decreasing
Option 2: Increases at a decreasing rate
Option 3: It is at his maximum point.
Option 4: None of the above
Correct Answer:
Starts decreasing
Solution :
Total utility decreases when marginal utility is negative because at that point, consuming one more unit of the product has a negative impact on total utility. Marginal utility is the rate of total utility.
Hence option a is the correct answer.
