Two people buying the same quantity of a good at the same

Explanation of Solution
Relative comparison of two different people satisfaction is not possible. Two people consuming the same quantity of good at the same price can have different satisfaction level according to their interest, so they cannot have the same marginal utility. Interpersonal utility comparison is not possible.
CONCEPT INTRODUCTION:
Marginal utility:
Marginal utility measures the additional fulfilment a customer earns from expending extra units of products or services. The idea of marginal utility is utilized by financial specialists to decide the amount of a thing customers are eager to buy. Positive marginal utility happens when the utilization of an extra thing builds the all-out utility, while negative marginal utility happens when the utilization of an extra thing diminishes the absolute utility.

Suppose that a power plant dumps byproducts into a nearby river, creating a negative externality for those living downstream from the plant. Producing additional electricity imposes a constant per-unit external cost of $490. The following graph shows the demand (private value) curve and the supply (private cost) curve for electricity. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $490 per unit.
