Where is the remaining 1 yuan?

First of all, 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 should not be counted, but the 1 yuan returned to each person should be added. That is: 3 * 9 + 3 * 1 = 30 yuan is just right!

This is a paradox, so analyzed: the customer gives 30 yuan to the boss, the boss refunds 5 yuan to the customer, then the boss only has 25 yuan, and then the waiter deducts 2 yuan, then the waiter has 2 yuan, and returns 3 yuan to the customer. This adds up to 25 + 2 + 3 = 30

I refunded 3 yuan to the guest and took 2 yuan for myself, a total of 5 yuan.

55 yuan should be refunded to the guest, and there is 25 yuan left.

What you are asking is: 3 yuan was refunded to the guest, so it was only 27 yuan, and the waiter took 2 yuan, which added up to 29 yuan, and there was 1 yuan to where?

27 can't add 2, should add 3 yuan to the guest refund.

So a total of 30 yuan is just right.

Won't look for me again.

In fact, this is a trick. Fooling people. The algorithm is wrong ...

Then the problem is at the back of 27 + 2 = 29

Customer -30··· 3··· 27

Waiter··· 2··· 2

Boss +30 ·· 5·· 25

It's clear when you look at it this way...

At the guest, the waiter refunded 3 yuan, and the guest had 28 yuan instead of 27

Obviously, the guest is lost.

You seem to have a bit of a problem with this category、、、、、、

"1 yuan food" refers to the low-cost food at about 1 yuan. With the development of the times, they have rarely appeared in stores and supermarkets, and gradually faded out of the sight of consumers.

With the arrival of autumn, the previous scorching heat has increased the demand for beverages, popsicles and ice cream, and many outdoor workers are finding that the "1 yuan" food used to cool down is now becoming less and less common. The reporter of "Workers**" also found that the commercial territory of these low-priced foods on the market is gradually shrinking, and consumers are increasingly calling for "1 yuan food".

$1 ice cream is not extinct.

"1 yuan food" refers to the low-cost food at about 1 yuan. With the development of the times, they have rarely appeared in stores and supermarkets, and gradually faded out of the sight of consumers.

Recently, ** ice cream has caused heated discussions on the Internet. Through on-the-spot visits, the reporter found that although the overall proportion of low-priced ice cream is not large, low-priced popsicles and ice cream of a few dimes and about 1 yuan are still sold in some shops and are not extinct. Some family-packed ice creams are only sold for more than 1 yuan each, and some are less than 1 yuan, such as 20-pack Yili pudding that is sold for less than 20 yuan in supermarkets.

Xiao Chu, who lives in Beijing's Changping District, told reporters that popsicles and ice cream for about 1 yuan are still easy to buy in community stores, but they are not easy on the street, and it is even more difficult to buy them in large shopping malls. "The weather is hot, and it is just necessary to eat a popsicle to cool down, but it is still very distressing to eat an ice cream that costs more than ten yuan a piece. ”

Through the visit, the reporter found that ice cream below 5 yuan on the market has rarely appeared, and it is difficult to buy it in many stores. Ms. Han, who likes to eat ice cream, told reporters: "Ice cream is no longer under 5 yuan.

This product is now more segmented, low-fat and healthy, and less 'friendly'. ”

1 yuan mineral water is also becoming more and more "rare". Zhao He, who needs to walk to and from work every day, told reporters: "It is very inconvenient to commute with water, and it is not guaranteed to be cold.

If you drink 3 bottles of mineral water a day, the unit price of 3 yuan is close to 10 yuan. Now Zhao He likes to buy Binglu, a mineral water that retails **1 yuan, but Zhao He said that it is becoming more and more difficult to buy such a low-cost mineral water brand.

At first, it was a total of thirty yuan, the boss was twenty-five yuan, the waiter was two yuan, and the rest were one yuan for every three people, and finally, he said that, each person spent nine yuan, a total of twenty-seven yuan, and the waiter's two yuan in twenty-seven yuan had been counted, and it was "3x."

$27. The waiter's hidden 2 yuan = 29 yuan" is to confuse our thoughts, 2 yuan has actually been added to 27 yuan, and in the end the remaining three yuan is one yuan for each of them, a total of 30 yuan, this question is very simple, but he added that sentence in it, it is difficult for us to turn around.

3 people actually paid 9 yuan each.

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

30-25=5, this 5 yuan is taken by the waiter!

The waiter gave them 3 yuan.

5-3=2 he doesn't have 2 yuan left.

Isn't 2+3+25 = 30?

So there is no less with the original.

3x3x3 - 2 yuan from the waiter's hiding = 25

$3 per person and $2 for waiters. A total of 5 yuan.

So in fact, there is no less than one dollar at all.

First of all, 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 should not be counted, but the 1 yuan returned to each person should be added. That is: 3 * 9 + 3 * 1 = 30 yuan is just right!

We can also calculate the other way around, let's start from the back, according to the boss's meaning, three people for a night to 2

5 yuan, because 25 is not divisible by 3, so we temporarily, just temporarily ignore 1 yuan, so 25 1 24 yuan 24 3 8 yuan, so the average person takes 8 yuan, but after the waiter came, he returned 3 yuan, an average of one yuan per person, because I just calculated it the other way around, so three people each took one more yuan, then 8 1 9 yuan, 3 9 27 yuan 27 yuan plus the waiter greedy 2 yuan, 27 2 29 yuan how is it 29 yuan, don't worry, just ignore the 1 yuan, remember, 29 1 30 yuan, so that's where this dollar is

That's not how money counts!

9*3=27 is the accommodation fee spent per person!

The 27 yuan already includes the 2 yuan that the waiter took away without permission, plus the preferential 3 yuan.

Just got it?

The algorithm you said is that at the beginning, each person paid 10 yuan, and now it is returned 1 yuan, which is 10-1=9, and only 9 yuan per person, 9 yuan per person for 3 people, 3x

9=27 yuan +

The 2 yuan hidden by the waiter = 29 yuan, but the 2 yuan that the waiter got was spent by 3 people, assuming that the 2 yuan of the waiter was a tip, then it is equivalent to 3 people paying a total of 2 yuan to the waiter, not 2 yuan to one person, so the money spent by each of the 3 people in the end should be 9 minus (3 divided by 2) money. That's it.

There's a problem with the logic! “3x9

$27. 2 yuan = 29 yuan from the waiter's hiding".

3 people 9 yuan per person, 3x

9 = 27 yuan - 2 yuan from the waiter = 25 yuan for one night.

If you follow it in the end you come wrong.

30 = 3 x 10 yuan - 2 yuan from the waiter = 3x9 = 27 yuan?

It's obviously wrong!

That dollar was not paid at all!

It's a kind of trick-like subject, if you follow his train of thought, you will only be puzzled, but a little bit of thinking will reveal the mystery. First of all, 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 should not be counted, but the 1 yuan returned to each person should be added. Namely:

3 * 9 + 3 * 1 = 30 yuan is just right!

Actually, the reason is very simple.

27+2, it doesn't mean anything, these two numbers can't be added together at all. The reason is very simple, what is 27, is the sum of 25 yuan of the actual room fee and the 2 yuan hidden by the waiter. It already contains 2, and adding 2 doesn't make sense.

Correct calculation: the actual room fee is 25 yuan, and the waiter hides 2 yuan, which is a total of 27 yuan; "The remaining 3 yuan was distributed to the three people, and each person was given 1 yuan", 27 + 3 = 30, which is the money paid by the first three people. In this way, there is no contradiction.

The title is from "3x

$27. The waiter's hidden 2 yuan = 29 yuan" to guide you to drill the tip of the bull's horns, if you think about it from this aspect, you will not get the answer.

It's an old problem, it's a numbers game.

Because it gives the impression that the meal cost is 30 yuan, but the actual meal price is 25 yuan. The 2 yuan that the staff embezzled was not from the meal money, but from the customer.

So the relationship should be 3x9=27, 27-2=25 (should be subtract rather than add), 25+5=30 (5 yuan is preferential).

Meal money 25It took 3 * 9 = 27 employees to swallow 2 yuan, and the problem behind it is around you. In fact, the answer is as simple as that.

Come on, let's look at the problem this way, it actually took a total of 27, and the title is my own. Then the meal money was given 25, and the employee swallowed 2 yuan, isn't that 25 + 2 = 27?
