A piece of money that was missing

Today is a logical problem, strictly speaking, not the reasoning problem, but also interesting.

Restatement of the problem:

3 people go to the lodging, 30 yuan a night. Three people each took 10 yuan to gather enough 30 yuan to give the boss.  Later the boss said that today's offer is only 25 yuan enough, take out 5 dollars to order the waiter returned to them, the waiter secretly hid 2 yuan, and then, the remaining 3 yuan to the three people, each divided into 1 yuan. So, at the beginning of each cut 10 yuan, now returned 1 yuan, that is, 10-1=9, each person only spent 9 yuan, 3 Each person 9 yuan, 3 *9 = 27 Yuan + The waiter hides the 2 yuan = 29 Yuan, also has one yuan money to go where?

Analysis and Solution:

This problem is a logical question, used to test that we can not withstand the flicker. In front of the information, we must first do is to maintain their own sober and independent thinking, do not be led by the information of the nose, thus losing their ability to think, into the wrong, into the "knowledge more more passive" dilemma. This is the J I learned from this problem.

Let's do the problem by ourselves:

We know that 3 people started out with a total of 30 dollars. In other words, the input of this question 30 yuan, then the 30 dollars is how to allocate it: The boss took 25 yuan, the waiter took 2 dollars, they took 3 dollars. There seems to be no less money, so how do they count? Why is there 1 dollars missing?

We walked along his train of thought:

Start each to dig 10 yuan, now return 1 yuan, namely 10-1=9, each person only spent 9 yuan, 3 person 9 yuan per person, 3 *9 = 27 Yuan.

This 27 yuan is divided into two parts: of which 25 yuan to the boss as the room rate, 2 dollars to the waiter. At this point, we understand, how can they put 27 to add 2, 2 itself is 27 inside AH. If you want to get 30 dollars, it should be: 27 dollars to pay out and 3 dollars left to add up is 30 ah.

"Confusion Concept", the construction of "thinking misunderstanding" is now a lot of high-level deception tricks, we must maintain independent thinking.
