The cost of accommodation is 30 yuan for 3 people, but it is one yuan less????

The front is all right, the back"3 9 27 The waiter hid 2 yuan 29 yuan, and one yuan went to **"Misleading.

The actual expenditure for each person was 9, a total of 27 yuan. And the waiter and the boss are earning this money, which is 25+2. That is, the 2 yuan hidden by the waiter came from the 27 yuan actually spent by the three people.

According to the boss's meaning, three people will cost 2 5 yuan for a night, because 25 is not divisible by 3, so we are temporary, just ignore 1 yuan for the time being.

So it's 25 1 24 yuan 24 3 8 yuan, so the average person gets 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 the 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 this is where this yuan is

The algorithm is wrong, you want to be wrong, give 30 yuan, refund 5 yuan, equal to 25 yuan, swallow 2 yuan, and leave 3 yuan, 25 + 2 + 3 = 30 yuan.

By the way, nonsense, is this question considered a high-IQ question? My teacher taught me when I was in the third grade of elementary school

10-5 3+1)*3+2=30 Can't be blinded by the title Can't follow him to say that 10-1 will be subtracted by one, in fact, the average consumption of each person is 10-5 3+1 instead of a simple 10-1 That's this 5 3 Pay attention, the logic is easy to be disrupted.

In fact, this question can only be regarded as a trick.

It's okay to actually do it.,The 27 yuan for 3 people actually includes the 2 yuan that the waiter hid.。

That's 27 yuan.

Each person returned another dollar, which is 3 yuan.

27 + 3 * 1 = 30 yuan.

That's it, just practice it and you'll understand.

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!

Each person would have taken out 10 yuan. Later, each person took back another one yuan, which means that each person only took out 9 yuan in the end. That's a total of 27 yuan.

The 27 yuan was given, who got it? The boss had 25 yuan and the waiter had 2 yuan.

27 2 29 This algorithm does not make sense. Because this 27 already includes this 2.

Because it should be 27 3 1 = 30 is the 27 given by three people plus one yuan for each person who returned to his hands, which is exactly 30 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!

3 people for 3 people, 30 for one nightEach person paid 10 yuan to make up 30 yuan. The boss said that 25 yuan was enough, and he returned 5 yuan, and the waiter hid 2 yuan, and the remaining 3 yuan was divided into the three people, 1 yuan per person. (The description is clear here, and the logic is also clear).

Analysis: $9 per person.

The accommodation fee is 25 yuan.

The waiter's tip is 2 yuan (automatically deducted).

Question: In this way, it costs $9+ per person

Where can the waiter hide 2 yuan = 29 yuan and pay one yuan?

Where not to use this dollar is logically wrong.

It should be 27-2=25! The boss charged 25 yuan, the waiter hid 2 yuan, and the three people paid a total of 27 yuan, which was just right.

25 of 1 3=

1x3=3 The boss refunds the money and the waiter deducts 2

8 3 + 1 = Later, the boss said that today's discount, only 25 yuan.

8x3+1)+1x3=3 boss refund + waiter deduction 2=303x9=27

8+1=9((8x3+1))1 is at the boss's place soon.

You can't apply both algorithms at the same time because the conditions are different. "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 + 2 yuan hidden by the waiter = 29 yuan" - this sentence itself is problematic, because the 2 yuan hidden by the waiter is included in the 27 yuan, which is obviously unreasonable. It should look like this:

27-2+5=30 yuan,

The two yuan hidden by the waiter is in the money spent by these 3 people, 9 yuan per person, 3 27 yuan = 25 yuan + 2 yuan for the waiter,,, I want to ask LS what do you mean by minus 2.

The algorithm is wrong! The house price is 25 yuan + the money returned to the three people + the money taken by the waiter = 30 yuan.

There are two algorithms, one of which can never be calculated. Unconventional algorithms.

The key to mathematics is with the = sign.

You='re not right.

How much does it cost? $25 or $27? Please find out the answer to this question.

The weather has not been very good these days, and it may turn sunny at the end of March, so if the sun is out for a few days in a row, you can consider going to see the sunrise, otherwise you will only see fog! If it costs, because I am a student, the ticket is half price fifty, not a student suggests that you can borrow a student ID card is very convenient, the food on the mountain is very expensive, such as a bottle of water under the mountain, two pieces halfway up the mountain, three pieces at the top of the mountain, a cake at the top of the mountain are three pieces, it is simply a price to sit on the ground, so prepare the necessary water and dry food before going up the mountain will save a lot of money! If you choose to find a place to rest at the foot of the mountain, about 50 to 100 can be, and then start climbing the mountain at 12 o'clock in the evening to see the sunrise, if the economic conditions allow, you can go to the hotel on the top of the mountain, but a few hundred is normal, and the rental fee of the padded jacket on the mountain is fifty-one, establish wear thick clothes to keep warm, I wish you a happy journey!

I went the day before yesterday. Tickets 100Tickets up the hill to and from 70

There are small hotels on the mountain. I asked for a single room because I was alone. 80.

Meals are more expensive. It's best to bring your own dry food. It doesn't matter if you can accept three times the price.

I just eat. Not an item.

This question is a long time coming.

In the end, each person spent 10 yuan, and their total consumption was 30

The boss gave a discount of 7 yuan, and if the waiter returned 7 yuan to them, their consumption was 23 yuan.

But the waiter only refunded them 3 yuan, and theirs spent 27 yuan.

The difference between 27 and 23 is exactly 4 yuan, and this 4 yuan is since the waiter was hidden.

If you think confused, it will be 30-27, which is not right, because the boss has a discount, if you calculate it, that one yuan is the boss's discount.

Method 2 The boss discounted 7 yuan, the actual discount was 3 yuan, and there was 4 yuan left, no more, no less.

Why does the waiter have an income of 4 yuan, it takes 3 people 27 yuan to have 4 in 27, 27+4 is meaningless.

27 = 4 + 23 The 27 yuan spent is 23 yuan at the boss 4 yuan at the waiter's office, and the total money is 30 = 23 + 4 + 3 at the boss's office, 23 at the waiter, 4 guests, 3 This kind of question is equal to the money, and the money spent by yourself = the money earned by others is OK, this question I have answered n times before.

3 people stayed, each person took 1 yuan, which is 3 yuan, plus only 23 yuan, it is 26 yuan, and the waiter took 4 yuan, which is 30 yuan.

The amount of money paid by the person is 27 = 23 handed over to the boss + 4 (yuan) stolen by the waiter.
