And what about 1 yuan? Where is the other 1 yuan?

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!!

It doesn't make sense to take 27+2=29!

27 yuan is 25 yuan for accommodation plus 2 yuan for the younger brother!

So much clearer!

If you still don't understand!

It's 30 bucks in total!

9 pieces per person.

A total of 27 pieces were produced.

There is only one piece left for each person, so there are three pieces! 27+3=30!!

This is 2 and 3 to confuse your mind! 27+2 is meaningless!

The 1 yuan was originally gone, because the last rent paid by the three of them was 25 yuan, and the waiter hid 2 yuan, that is, they just paid (10-1) x 9 = 27 yuan each, and the latter result has nothing to do with the previous 30 yuan.

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

The room was 25 yuan, they paid a total of 27 yuan, and the other 2 yuan was given to the waiter, no.

In fact, you must not use 27+2 for this question, this is just a 27-2 problem.

It wouldn't be wrong with the room price being 25 yuan, they wouldn't be wrong with paying 27 yuan, and it wouldn't be wrong with giving it to the waiter for two days.

Don't let $30 get it reversed.

Did you miscalculate? 5 yuan is divided among 3 people, and 1 yuan for one person is not 2 yuan? When the service fee is just right!

Halo, what does it mean, arithmetic problems for elementary school students?

I have a headache about this

"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?

Problem description: Xiao Ming saw a pair of shoes for 97 yuan, and he had no money. So he borrowed $50 from A and B. After he bought 97 yuan of shoes, he put away the remaining 3 yuan, one of which was a volt key element, and then returned A and B for one yuan. Then Xiao Ming owes A and B 49 yuan each.

Now add up the 49 yuan of A and B to 98 yuan, plus Xiao Ming's one yuan is equal to 99 yuan, which 1 yuan went to ** cracking? Analysis:

3 divided by 2 equals.

Xiao Ming should first lack the source and return the 3 pieces to A and B.

97 divided by 2 is equal to yuan) and then returned to A and B.

One yuan is still with Xiao Ming.

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.

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!

A, B, and C stay in the hostel together, and each person spends 10 yuan, a total of 30 yuan to pay the accommodation fee. But later, the manager only charged 25 yuan and asked the waiter to refund 5 yuan to the three people. The waiter wanted 5 yuan to give the three people a bad score, so he deducted 2 yuan as a tip and paid 1 yuan per person.

So in the accommodation fee of 30 yuan, the three people each spent 9 yuan, a total of 27 yuan, and the waiter took 2 yuan, so what about 1 yuan?

This question is confusing concepts.

The key is at the end.

The three of them are paying, and the accommodation fee is being paid for.

Later, the three of them each spent 9 yuan, a total of 27 yuan, 25 yuan for accommodation, and 2 yuan for the waiter, which happened to be 27 yuan.

So in the accommodation fee of 30 yuan, the three people each spent 9 yuan, a total of 27 yuan, and the waiter took 2 yuan, so what about 1 yuan? Read this sentence carefully The second half of the sentence is withdrawn, and the first half of the sentence is not retreated. So this sentence has to be said: "Of the 25 yuan accommodation fee, the three people each spent 9 yuan, a total of 27 yuan, and the waiter took 2 yuan."

Then the answer is obvious!
