Question

Observe the given table and answer the questions given below it:
| Unity of a commodity | Total Utility (TU) units | Marginal Utility (MU) units |
| --- | --- | --- |
| 1 | 6 | `square` |
| 2 | `square` | 5 |
| 3 | 15 | 4 |
| 4 | 15 | `square` |
| 5 | `square` | -1 |
Questions:
Complete the above table.
a. When the total utility is maximum, marginal utility is - `square`
b. When total utility falls, the marginal utility becomes - `square`

Accepted Answer

> [!TLDR]
> Using MU = TU(this unit) − TU(previous unit), the completed table is TU = 6, 11, 15, 15, 14 and MU = 6, 5, 4, 0, −1. When total utility is maximum, marginal utility is zero; when total utility falls, marginal utility becomes negative.

> Marginal utility (MU) is the change in total utility (TU) from consuming one additional unit, i.e. MU of the nth unit = TU of n units − TU of (n−1) units. Using this the blanks are filled:
>
> - Unit 1: MU = TU(1) − TU(0) = 6 − 0 = 6
> - Unit 2: TU = TU(1) + MU(2) = 6 + 5 = 11
> - Unit 3: TU = 15, MU = 15 − 11 = 4 (given, consistent)
> - Unit 4: MU = TU(4) − TU(3) = 15 − 15 = 0
> - Unit 5: TU = TU(4) + MU(5) = 15 + (−1) = 14
