One day, three people go to the hotel at the same time, ten yuan per person, just thirty yuan, and t

There is also one yuan in the 25 yuan charged by the boss. 25 yuan divided by 3 equals so it is equal to each person paid. Three people add up to 1 yuan.

This is a trick and this calculation is incorrect. is pushing, the boss has 25 yuan; Extrapolating, each person pays nine yuan and subtracts the waiter to take two yuan, and the boss receives twenty-five yuan.

The calculation is wrong.

Tricks. They pay nine yuan per person in the hotel, 3 9 27 is actually the 25 yuan charged by the owner plus the 2 yuan and 27 yuan charged by the waiter, but he adds the two yuan charged by the waiter, of course, it is not right, and if the two yuan is added in this way, it is equivalent to repeating the addition, and it should be added to the three yuan returned to them.

The hotel pays 30 yuan, the boss returns 5 yuan, and the waiter gets 2 yuan from it.

3 people pay 9 yuan per person 3x9 27+2=29 It is true that there is not a single yuan.

But think differently.

Ignore the waiter for now.

The boss refunded 3 yuan 3x9 27+3=30 so that there was no missing.

Why was it less than one dollar before?

Because I didn't figure out the difference between $3 and $2.

2 yuan is obtained by the waiter, if the guest room rate is 9 yuan.

Then the owner of these two dollars should be the owner of the shop.

Because it's 27+3.

The lost dollar was taken by the customer himself.

Three people stayed in a store, and the result was 10 yuan per person, a total of 10 3 = 30 yuan.

Each person returned 1 yuan, that is, 9 yuan was spent per person, and the three people spent a total of 27 yuan. Of the 27 yuan, the boss left 25 yuan, and Xiao Er left 2 yuan privately.

Add the 3 yuan returned, and the result is exactly 30 yuan.

Conclusion: This question confuses people mainly because it separates the 2 yuan from the 27 yuan, and the algorithm of the original question mistakenly believes that the 2 yuan left by Xiao Er is not included in the 27 yuan, so there is an error result of 1 yuan less; In fact, the 2 yuan left without permission was included in the 27 yuan, plus the 3 yuan returned, and the result was exactly 30 yuan.

Set a contribution of $x per person.

From the inscription: 3x+5=30

Solution x = 1 yuan per person is returned, and no one happens to pay 1+

The total contribution of the three people is about 28 yuan, plus the waiter's 2 yuan, which is equal to 30 yuan.

The question of this question is where the dollar went, and all of you answered the question correctly, in fact, the dollar was divided among the three renters Thank you!! Bogo answers.

In this question, the key is that the questioner first guides the two yuan hidden by the waiter into the "3 yuan", which forms a conceptual dislocation in our thinking!

1. There is nothing wrong with spending 9 yuan per person! Compared with the 30 yuan handed over at the beginning, the remaining 3 yuan is the 3 yuan returned by the waiter, 1 yuan per person, and he took it back.

2. The 2 yuan hidden by the waiter is included in the 27 yuan that has been paid.

3. The 27 yuan paid is composed of 25 yuan charged by the boss + 2 yuan hidden by the waiter!

This is a question of the questioner leading the way in the wrong direction.

In fact, this is a matter of confusion.

At the beginning, the three people paid a total of 3x10 = 30 yuan, and the boss asked the waiter to return 5 yuan to the three people, and the boss received 25 yuan, but the waiter secretly hid 2 yuan and only returned 3 yuan to the three people, so the last three people only paid 30-3 = 27 yuan in total, and there was no concept of 30 yuan.

30 yuan = 25 yuan (received by the boss) + 2 yuan (private collection of the waiter) + 3 yuan (one yuan per person for three people) Everyone only needs to track the whereabouts of 30 yuan!

I wonder if you can understand this explanation?

Because 27 = 25 + 2, not 3 * 9That is, the rent + the money that the waiter secretly took. plus the returned 3 yuan, that is, 27 + 3 = 30Not a single point was missing.

Is that how it counts?

Everybody spent 9 yuan, 27 yuan, minus the 2 yuan the waiter paid, and the boss got 25 yuan.

Each person spent 9 yuan, and what does the 2 yuan that the waiter hide adds up?

Giving = Receiving.

9 * 3 = 25 +2 This is true.

Throwing 2 to the left should be subtraction.

This question is very nonsensical, and ordinary thinking can't solve it.

I don't know, there's a lot of money, and I don't know how to do it.

1. The 9 yuan spent per person has included the 2 yuan hidden by the waiter (that is, ***25 yuan + 2 yuan hidden by the waiter = 27 yuan = 3 * 9 yuan), therefore, when calculating the composition of the 30 yuan, the 2 yuan hidden by the waiter cannot be counted, but the 1 yuan returned to each person should be added. That is: 3 * 9 + 3 * 1 = 30 yuan is just right!

Think about it another way. The three people paid a total of 30 yuan, spent 25 yuan, and the waiter hid 2 yuan, so each person spent 9 yuan, plus the 1 yuan they shared, it was exactly 30 yuan. So the dollar was found.

Summary: This question confuses people mainly because it separates the 2 yuan from the 27 yuan, and the algorithm of the original question mistakenly believes that the 2 yuan left by the waiter is not included in the 27 yuan, so there is an error result of 1 yuan less; In fact, the 2 yuan left without permission was included in the 27 yuan, plus the 3 yuan returned, and the result was exactly 30 yuan.

2, a pound of money refers to whether it is green onion white or green is a dollar a pound, when he bought the green onion white and green onion separately, the green onion white 7 cents green onion green 3 cents, in fact, its weight is not changed, but the unit price has changed, the green onion white received 3 cents per catty, the green onion received 7 cents per catty, so in the end 50 yuan was bought.

3. 5 days.

Many people don't think about this question and say it's seven days. It works in a very simple way.

You take a piece of paper and draw it and it comes out. It's a very simple question.

Buy 10 for money, and leave 10 cores after eating. Change 3 more peaches, and after eating, there are 4 cores left.

Change 1 more peach, and after eating, there are 2 cores left. 1 peach sold on credit, and 3 cores left after eating. Give all the cores to the one who sells peaches, the one who pays the credit.

So, you ate a total of 10 + 3 + 1 + 1 = 15 peaches.

This is the method that everyone knows. There's another way.

Don't buy ten at a time. Buy it separately.

Three for the first time. Two for the second time. Two for the third time. Such. Very simple. It's also 15 pcs.

One dollar in the hands of the boss. 10 yuan per person, 1 yuan was returned, and 9 yuan was actually taken out per person; plus the waiter's $2, a total of $29; The service has 5 yuan in his hand, and it stands to reason that the boss should only get 24 yuan, but in fact, the boss gets 25 yuan, so this yuan is in the boss.

This kind of question is just going around and around, and it's not interesting. 3 people gave 30, and then the boss left 25, and the guy took 5 yuan.

Step 2: The guy gives money to 3 people, 1 yuan each, and the guy has 2 dollars left.

Now it's clear that the boss has 25 bucks, the guy has 2 bucks, and 3 people have taken 3 back.

The guy kept 2 yuan for himself, and if the money was added up in the end 3x9=27 plus the 2 yuan in the guy's hand 27 + 2 + 29, where did the 1 yuan go? This is just misleading you.

The guy left 2 yuan and the boss's 25 is just 27 yuan, which is the money given by those 3 people. The remaining 3 pieces were taken back by the 3 men.

The first question: Are you saying that the three people each returned one yuan, that is, the three people paid a total of 27 yuan, which is true, but the waiter received 2 yuan, that is, 27-2 = 25 (instead of 27 + 2 = 29), so the remaining 25 yuan is the boss's, and that one yuan does not exist at all!

The first one, draw out 6 yuan, 25 = 9 + 8 + 8, plus 3 is 10 + 9 + 9. So the vulnerability is a problem of 25 and 26.

One dollar is in the one dollar divided among the three people.

Let me answer question 3, the snail will be able to crawl out during the day on the seventh day!

I'm depressed, I'm too lazy for you, think for yourself...

The whole question is this, right?

Question: There are 3 people who go to the hotel, 30 yuan per person 10 yuan Today's festival is only 25 yuan, ask the waiter leg 5 yuan to give them, the waiter takes 2 yuan, take 3 yuan to give them 3, 1 yuan per person, they pay 9 yuan, 3 times 9 and so on 27, 27 plus 2 and 29, and 1 yuan?

Answer: In fact, each person paid 25 yuan, and the waiter was greedy for 2 yuan, plus 3 yuan, 30 yuan is enough Note 1: This is a typical problem of stealing beams and changing columns.

Note 2: The question should be "The waiter took [two] dollars", which is a mistake made by the questioner. First, we should figure out what "each of them came out with nine bucks" is going on:

Threesome: 10 3= 30 Boss receives: 30-5= 25 per person to the boss:

25 3= 25 3 Each person is taken by the waiter: 2 3= 2 3 The total amount given to the boss and the waiter per person: 25 3 + 2 3= 9 10 yuan per person is given, and the total amount given to the boss and waiter is 9 yuan per person, so 1 yuan should be recovered.

Secondly, we should figure out why there is a phenomenon of "there is still one dollar to go to **": The total amount of three people to the boss and waiter: 25 + 2 = 27 (that is, "each person gave nine dollars" 9 3 = 27) [ps:

These 27 include the 2 yuan taken by the waiter] Q: Why is there a phenomenon of "there is still one dollar to go"? A:

The author deliberately added "2 yuan taken by the waiter" to the 27 yuan that already included "2 yuan taken by the waiter" to numb everyone, but did not add the "3 yuan that should be recovered". Actually, when I said, "Each of them paid nine dollars, and the two dollars the waiter took included in the three nine dollars," do you already understand? That is, it should have been:

10 3-5)+2+3=30 is counted as: (10 3-5)+2+2=29

Got it?

At first, it was 30 yuan, 5 yuan was returned, and now it is 25 + 5, and then the waiter takes 2 yuan, which becomes 25 + 3 + 2.

After the 2 yuan is taken away, there is 25 + 3 yuan left, 3 yuan is returned, and 25 is left, let's calculate the 25 + 2 yuan 27 from them, yes, they are nine yuan out of one person!

This is conceptual confusion.

In fact, it only costs $27 in total, of which the boss gets $25 and the younger brother gets $2.

If you want to say that the original payment of $30 is fine, the owner gets $25, the younger brother gets $2, and the three residents get $3 back.

That's clear enough.

The money returned was one dollar, but the total amount paid to the waiter by three people together was 28, and the money made up by the waiter was mixed with the money given.

There are 3 people to stay, 30 yuan a night. The three of them each paid 10 yuan, and 30 yuan was handed over to the boss.

Later, the boss said that today's discount was only 25 yuan, and he took out 5 yuan and ordered the waiter to return it to them, and the waiter secretly hid 2 yuan, and then distributed the remaining 3 yuan to the three people, each of whom received 1 yuan.

In this way, at the beginning, each person paid 10 yuan, and now it is returned 1 yuan, that is, 10-1 = 9, and only 9 yuan per person, 9 yuan per person for 3 people, 3 x 9 = 27 yuan + 2 yuan hidden by the waiter = 29 yuan, and one yuan went to **???

Answer: Each person took out 9 yuan, not 10 yuan, so the store owner took 25 yuan, and the correct one should be 27-25=2 yuan. The $2 is at the waiter's.

Summary: This question confuses people mainly because it separates the 2 yuan from the 27 yuan, and the algorithm of the original question mistakenly believes that the 2 yuan left by the waiter is not included in the 27 yuan, so there is an error result of 1 yuan less; In fact, the 2 yuan left without permission was included in the 27 yuan, plus the 3 yuan returned, and the result was exactly 30 yuan.

The boss took 30 yuan and took out 5 yuan for the waiter to find the guest... The boss actually accepted 25 yuan...

The waiter hid 2 yuan··· Find a guest for 3 yuan.

The guests paid 30 yuan, but found 3 yuan, and the guests spent a total of 27 yuan·· The 27 yuan spent by the guests, including the 25 yuan from the boss and the 2 yuan from the waiter, is there still a single yuan? ~

If you haven't figured it out... When I didn't say anything... Break your toes and count on your own fingers...

This can't be counted that way.

Briefly talk about the flow process of this 30 yuan.

At first, it was 10 yuan per person.

Later, after paying the money the boss 30 yuan.

After the money is refunded the boss 25 dude 5

In the end, after returning the money, the boss 25 guys, 2 guests, 1 each, so look at it, the money is right.

So according to the algorithm in the question, what went wrong?

The fault is that the total amount of money has changed, and it is no longer 30 yuan. It's $27.

Because after returning 1 yuan per person, it is equivalent to 9 yuan per person. That is to say, a total of 27 yuan was paid.

The boss gets $25 and the guy $2.
