Q3 of 31 Page 1

Which of the can be referred to as ‘point of satiety’?

i) Marginal Utility is negative


ii) Marginal utility is zero


iii) Total Utility is rising


iv) Total Utility is falling

Marginal utility is zero


Explanation


The utility is the want-satisfying power of commodities. Total utility (TU) is the sum of the total utilities derived from the consumption of a defined unit of commodities. Marginal utility (MU) is the addition made to the total utility when an additional unit of a good is consumed. The relationship between TU and MU can be explained as:


• When TU increases at an increasing rate, MU rises.


• When TU becomes maximum, MU becomes 0. This is the point of satiety.


• When TU falls, MU becomes negative.
