I chose D

I see why C is correct, but why can’t D also be correct?

If the client’s noticed that they had been overcharged, then they won’t pay the amount they’d been overcharged with and that would affect their profit because

Correct Answer: (C)
Reason: The accountant assumes that because the number of clients overcharged equals the number of clients undercharged, the total financial effect will cancel out. However, this ignores the possibility that the total amount of overcharges might be larger than the total amount of undercharges. If BanqueCard overcharged clients by a larger total amount than it undercharged, then correcting the errors would reduce its profits.

Eliminating the Other Options:
(A) Relying on the reputation of BanqueCard as a trustworthy credit service to maintain the company's clientele after the error becomes widely known
❌ Incorrect: The argument is about whether correcting billing errors will affect profits, not about whether BanqueCard will maintain its clientele. While reputation could be a relevant concern for long-term profitability, it is not a flaw in the accountant's reasoning about the immediate financial impact of corrections.

(B) Failing to establish that BanqueCard charges the same rates of interest for all of its clients
❌ Incorrect: The issue is not whether interest rates vary among clients. Even if different interest rates apply, the key flaw in reasoning is assuming that overcharges and undercharges cancel out without considering their total monetary impact.

(D) Assuming that the clients who had been overcharged by BanqueCard had not noticed the error in their credit bills
❌ Incorrect: Whether or not clients noticed the errors does not affect the conclusion about BanqueCard’s profits. The argument focuses on the company's overall financial standing rather than individual client awareness.

(E) Presupposing that each one of BanqueCard's clients had either been overcharged or else had been undercharged by the billing error
❌ Incorrect: Even if some clients were charged correctly, the critical issue is whether the total amount of overcharging equals the total amount of undercharging. This option does not address the key flaw in the accountant’s reasoning.

An assumption is something that the author of the statement (In this case the accountant) should believe to be true. That may or may not be true in real life, but as long as author believes it, its a valid assumption.

Lets examine option D

Assuming that the clients who had been overcharged by BanqueCard had not noticed the error in their credit bills - Does the accountant need to assume that error went unnoticed? Not at all. The clients may have noticed, yet the accountant's statement may hold true.

Thus Option D is incorrect as it says the accountant has assumed something he clearly didnt.

Hope this helps.

Cheers,
Su!
