Three people went to a hotel to stay in three rooms, at $10 per room. So they paid the owner a total of $30. The next day, the owner thought that three rooms only cost $25, so he told his employee to return $5 to the three guests. However, the employee was greedy and gave each guest back only $1, keeping $2 for himself. As a result, each of the three guests ended up paying $9, meaning they spent a total of $27. Adding the $2 that the employee kept for himself, the total amount comes to $29. But they three paid a total of $30 back then, so where is the remaining $1?

The 2 yuan I paid is already included in the 9 yuan they paid; 27–2=25. Adding the 5 yuan refunded by the owner gives a total of 30

The original expenditure was 30: 25 went to the boss, 2 to the assistant, and 3 to the customer, so it was balanced. The current expenditure is 27: 25 goes to the boss and 2 to the assistant, which is also balanced. Do not confuse the recipients (the assistant receiving 2) with the expenditures (the customer’s 27); otherwise, the accounts will not be balanced.

It seems that many marine professionals should take the CPA exam.

A typical case of misrepresentation: the two conditions are that the three people spent a total of $27 and that the three people paid a total of $30; only one of these conditions can be true. If one wants to deceive others, at least one of these conditions needs to be altered so that it doesn’t start with “the three people”. This would make the deception more effective

This is a misleading question; expenses and income cannot be mixed together when calculating

Hehe. It’s easy to get confused

This question is quite interesting; it subtly manipulates the concepts involved
