6 In microeconomic theory, the opportunity cost, also known as alternative cost, is
the value (not a benefit) of the choice in terms of the best alternative while making a
decision. A choice needs to be made between several mutually exclusive alternatives;
assuming the best choice is made, it is the "cost" incurred by not enjoying the benefit that
would have been had by taking the second best available to the consumer.

9 Explanation With Schedule and Diagram:
We assume that a man is very hungry. He takes the paratha successively. The marginal
utility of the successive paratha decreases, ultimately, he reaches the point of satiety.
After this point the marginal utility becomes negative, if he is forced further to take next
unit. The behavior of the consumer is indicated in the following schedule:
Units of commodity Marginal utility Total utility
1 10 10
2 8 18
3 6 24
4 4 28
5 2 30
6 0 30
7 -2 28
On taking the 1st glass of water, the consumer gets 10 units of utility, because he is very thirsty.
When he takes 2nd paratha, his marginal utility goes down to 8 units because his hunger has
been partly satisfied. This process continues until the marginal utility drops down to zero which
is the saturation point. By taking the seventh parataha r, the marginal utility becomes negative
because the hunger of the consumer has already been fully satisfied.
The law of diminishing marginal utility can be explained by the following diagram drawn with the
help of above schedule:
