There were 3 people who went to stay, 30 yuan a night, and the three people each paid 10 yuan to mak

I cut it and was stolen to change the concept. 25 yuan in the boss's hand, three yuan in the hands of the three people, and two yuan in the waiter's hand. Nine yuan and two yuan are not in the same system.

This is certainly the case below.

It only cost $9 per person plus $2 for the waiter.

So the total amount is 29 yuan, so the remaining 1 yuan is taken.

I'll ask this question 3 people 9 yuan each, 3 x 9 = 27 yuan + 2 yuan hidden by the waiter = 29 yuan.

This is a misunderstanding, 27 yuan is paid by 3 people, and the 2 yuan is taken by the waiter, and his 27+2 has no practical meaning at all.

It should be the money paid by the hosts = the money taken by the waiter and the boss.

So 10-1 = 9, 3*9 = 27, 27 = 2 + 25

JB waiter: What are you doing greedy for other people's money, you can't settle the account in the end If you are found out, you have to post 10 yuan upside down So you must be kind.

3 people actually paid 9 yuan each.

The boss took 25 yuan, and the waiter hid 2 yuan.

By the way, you don't think you're done yet.

I haven't even asked the questions!

3 people, no one 9 yuan 3x9 = 27, plus the waiter secretly hid 2 yuan 27 + 2 = 29, ask where is the yuan, yes?

Your 27+2 is not right at all, because it is not a thing at all.

Three people spent a total of 3 * 9 = 27 plus the 2 pieces that the waiter hid for a total of 29 so what about the remaining piece.

The three of them paid a total of 25 plus the three yuan returned, and the three of them paid a total of 25+3

28 yuan, plus the 2 yuan taken by the waiter, isn't it exactly 30.

lzDon't mislead.

The logical loophole is actually 30 yuan paid and 3 yuan returned.

I didn't know that there was that dollar, and I didn't know it later.

Don't think about it, bro

Analysis: The three of them paid a total of 30 yuan, spent 25 yuan, and the waiter hid 2 yuan, plus the 3 yuan he shared, which was exactly 30 yuan. 25 + 2 + 3 = 30, so this dollar is 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.

Hope it helps

The final addition of this question is incorrect.

Because the 2 yuan hidden by the waiter is 9 yuan paid by 3 people, and the 3 yuan returned to 3 people is not 9 yuan paid by 3 people, so the 3 x 9 = 27 yuan paid by 3 people includes the 2 yuan hidden by the waiter, because these two yuan were not returned to them, or the money they spent, and the amount of money really returned to them should be the 3 yuan.

So 3 9 = 27 yuan paid by 3 people.

Refund $3 for 3 people.

Sum: 27 + 3 = 30 yuan.

The amount of money has not decreased.

If the waiter hides 5 yuan, isn't it 30 + 5 = 35 yuan.

The actual algorithm is: 3*9-2=25 yuan.

Solving algorithmic problems.

At the beginning, the boss charged 25 yuan + 2 yuan hidden = 27 yuan.

3 people each out 9 yuan, exactly equal to 27.

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 it only costs 9 yuan per person, 9 yuan per person for 3 people, 3 x 9 = 27 yuan, and now it is 1 yuan back 2 yuan = 29 yuan hidden by the waiter, and one yuan has gone to **???

The waiter secretly hid 2 yuan, which means that the 3 people also paid another 2 yuan. Therefore, it is necessary to deduct 2 yuan first and divide it by 3 to get that each person has paid about yuan.

30 in addition to the 5 yuan refunded and 25 yuan in the hands of the boss, 25 plus 3 yuan in the hands of 3 people, plus the 2 yuan taken by the waiter, is not 30.

This set of questions made a logical error: in fact, it is very simple, these three people actually only paid 9 * 3 = 27 yuan each, of which the 27 yuan is divided into two payments, the first accommodation fee is 25 yuan, and the second waiter is 2 yuan. If you want to make up 30 yuan for the exam, it is 25 accommodation fee + 2 yuan, and the waiter falls +1 yuan (1 yuan per person returns) + 1 + 1

This question is fully solved.

The three of them spent a total of 27 yuan, the boss earned 25 yuan, and the buddy earned 2 yuan. It's exactly 27 yuan, don't be misled.

I know! The waiter hides 2 yuan, plus the original ten yuan per person, which is equal to 32 yuan, minus the free 5 yuan, which is equal to 27 yuan, and then divides by three to get 9 yuan, therefore, the answer is that each person originally spent 10 yuan, and the discount is 5 yuan, that is to say, each person paid an average of 25 divided by 3, and got 8 and 1/3 of 1 yuan, plus one yuan recovered per person, 9 and 1/3 of 1 yuan, multiplied by three plus 2, to get 28 + 2 yuan hidden by the waiter, 28 + 2 = 30 yuan, so 1 yuan is not less, but the algorithm is wrong, Don't be fooled.

Actually, I thought of a better understanding and more understandable answer: that question has been circulating on the Internet for a long time.

In fact, the problem lies in singular and negative numbers. It's really simple. In elementary school, I learned singular and negative numbers.

Where did the dollar he asked go? In fact, the question was simply asked the wrong question, or there was no answer at all. The real final answer, or the loophole of the question, is singular and plural.

There is a problem with this problem, and the problem is the gap between singular and plural.

That one dollar went out of this formula: 3*9=27 2=2 disappeared from this arithmetic.

His expression was wrong, he spent 27 yuan to live in the hotel, but the boss received 25 yuan, and the two yuan for Xiao Er was the difference between the two. Therefore, the actual cost is 25 yuan for the boss + 2 yuan for the waiter black + 1 yuan for 3 people, which is 3 yuan = 30 yuan.

3 x 9 = 27 yuan Now it's back 1 yuan The 2 yuan that the waiter hid = 29 yuan, and there is one more yuan to go to**?? And this algorithm is wrong. The 2 yuan of the waiter black should be subtracted rather than added.

It's elementary school math that didn't work. The actual cost of staying in a hotel is 3x9=27 yuan. Plus the money returned is 27 + 3 x 1 = 30 yuan.

No more, no less 3 9 = 27 27-2 (waiter's money) = 25 boss's money.

Tell you that the extra dollar doesn't exist at all.

Forehead... Only the ordinary way ...

Just think about it differently. If it was 9 yuan per person, the three of them paid a total of 27 yuan, including 25 yuan for the boss and 2 yuan for the waiter. Therefore, using 27 yuan plus the 2 yuan hidden by the waiter is obviously incorrect, and the 3 yuan that should really be added should be the 3 yuan recovered.

Therefore, if the algorithm of this problem is incorrect, there is no way to talk about the unity. Thinking must not be misled by the title.

Because the 3*9=27 yuan paid by the three of them already includes the 2 yuan received by the waiter. So yes. 3 * 7 - 2 + 5 = 30 yuan, this is correct.

Or 3 * 9 = 27 plus 3 yuan that 3 people have already received, 27 + 3 = 30 yuan is also correct.

Use your brain, alas.

3 9 = 27 = 2 pieces from the waiter + 25 pieces left by the boss.

There are 30 customers in total, 3 waiters, and 25 bosses.

3+2+25=30, 27 spent, 2 pieces of waiter, can you add them together???

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. The main reason why this question confuses people is that 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.

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

One: Pay 30 yuan: 25 yuan for the boss plus 2 yuan for the waiter plus 3 yuan for return.

2: Pay 30 yuan and return 3 yuan. There were only twenty-seven dollars left: twenty-five dollars for the boss and two dollars for the waiter.

The three of them paid a total of 25 plus the three yuan returned, and the three of them paid a total of 25+3

28 yuan, plus the 2 yuan taken by the waiter, isn't it exactly 30.

Dude, don't mislead.

The one yuan is in the boss's place, if it is charged according to the person, 9 yuan per person, 3 people get 27 yuan, of which 2 yuan is taken by the waiter, and the boss is only 25 yuan.

This kind of question is a test of whether people are proficient in the order of operation, first find 5 yuan, it is impossible for 3 people to divide it equally, and then there are 2 yuan left in the waiter's place, and 2 yuan cannot be divided equally by three people.

25 is for the boss, 2 yuan is for the waiter, and there are three yuan for them, so the 27 has already wrapped the waiter's money.

The boss charges 25 yuan. The remaining 5 yuan is divided into 4 people, and the waiter is 2 yuan, and the three of them are one yuan each.

Secretly changed the concept, 3 people spent a total of 27 yuan (including 2 yuan for the waiter), 3 yuan has been returned to the hands of the guest, it should be 27 + 3 = 30

This was originally wrong, and three people spent 9 * 3 = 27 yuan. And the boss got 25 yuan, and 2 yuan was taken by the waiter, so 25 + 2 = 27

You're so good, I'm speechless!

That dollar is no less.

1. Each of the three people took out ten yuan to the boss, and the boss charged a total of 30 yuan 2, and the boss took out five yuan to the waiter, and there was 25 yuan in his hand.

3. The waiter is greedy for two yuan, and he has 2 in his hand

4. The waiter gave the three people one yuan each, and the three people had 3 yuan 5, the boss's 25 + the waiter's 2 + the three people's 3 = 30 yuan, and the landlord's algorithm was wrong! 9 * 3 = 27 yuan, of which the actual accommodation fee is 25 yuan, and the waiter is greedy for 2 yuan in the amount of money refunded by the boss, so the actual total amount is 27 yuan, obviously, the money has been settled.

The 27+2 yuan proposed in the question is actually a double calculation of 2 yuan, and the 27 yuan includes the 2 yuan that the waiter is greedy, and the calculation is wrong again.

The algorithm is wrong, and the 27 yuan paid by the three people already includes the 2 yuan stolen by the waiter.

At the beginning, each person paid 10 yuan, 10x3 is equal to 30, the boss only needed 25 yuan, and the waiter took two.

Yuan returned three yuan, in fact, the money is not less, but the algorithm is different, on the surface, it seems that the 10 yuan per person is minus the return.

1 yuan, 10-1 is equal to 9 is not wrong, but the total number has changed, the boss wants 25 yuan + returned 3 yuan = 28 yuan, the average score is 28 divided by 3 is equal to yuan, this question actually tests whether we use the word "average", the average two words in arithmetic are often ignored, so this phenomenon will occur, the total number has changed, the average amount of money paid by the three of them is not the beginning of the payment of 10 yuan minus the return of 1 is equal to 9 yuan, it should be the boss to ask for 25 yuan + returned 3 yuan = 28 yuan, The average score of three people should be 28 divided by 3 = yuan.

Yuan. Why? First of all, let's confirm:

They give the boss only: 25 yuan. 25 yuan divided by 3 yuan, then it is yuan, everyone out of yuan:

yuan, plus the 1 yuan returned by the waiter, doesn't that mean that each person has: yuan? Yuan per person multiplied by 3 people equals Yuan.

Plus the waiter's 2 yuan: equal to yuan, that is, 30 yuan!!

The correct answer is: that one yuan is already in 25 yuan.

25 3 = yuan.

Rent paid per person.

There is actually that much money per person.

The three of them have so much money in total'

Yuan = 30 yuan.

The total amount of money.

There are three people to stay, 30 yuan a night, three people each paid 10 yuan to make up 30 yuan to the boss later, the boss said that today's discount is only 25 yuan is enough, the boss took out 5 yuan and ordered the waiter to return it to them, the waiter secretly hid 2 yuan, and then, put the rest.

3 yuan was distributed to the three people, each of whom received 1 yuan, so that at the beginning, each person paid 10 yuan, and now it is returned 1 yuan, that is, 10-1 = 9, each person only spent 9 yuan, 3 people 9 yuan each, 3 9 = 27 yuan + the waiter hid.

2 yuan = 29 yuan, and 1 yuan went to **???

In fact, "3 people have a total of 27 yuan, and 2 yuan is 29 yuan in addition to the shopkeeper's second, and where does the one yuan go" This is a false proposition).

The boss charged 25 yuan.

Xiao Er received 2 yuan.

That is to say, three people gave 27 yuan.

And at the beginning, the three people gave 30 yuan.

Xiao Er paid back 3 yuan.

That is, the three of them finally gave 27 yuan.

That's fine.
