The following is the schedule representing the marginal utilities obtained by a consumer from consuming good X and marginal utility of a rupee is 2. State the number of units being consumed by him at a prices of ₹6 to obtain his equilibrium
| Unit Consumed | 1 | 2 | 3 | 4 | 5 |
| $MU_X$ (in units) | 16 | 14 | 12 | 10 | 6 |
Answer & explanation
Correct answer: option 2
The correct answer is option (2) : 3 units
Given marginal utility of a Rupee = 2
A consumer will be in equilibrium when MU (₹) = Price (₹)
We have to find equilibrium when P =6
Thus, the units at which the marginal utility in rupees = 6, this will be the equilibrium.
| Unit Consumed | 1 | 2 | 3 | 4 | 5 |
| $MU_X$ (in units) | 16 | 14 | 12 | 10 | 6 |
| MU (in rupee) -MU (util)/MU of a rupee (i.e. 2) | 8 | 7 | 6 | 5 | 3 |
The MU in rupee is equal to 6 at 3 units. This is the point of consumer equilibrium.
