Three people stay in the hotel, three people stay in the hotel, each person 100 yuan.

Today, Xiaobian will share with you the knowledge of three people living in a hotel, and it will also analyze and answer the answer of three people living in a hotel per person 100 yuan. If you can solve the problem you want to know, pay attention to this website.

Three people stay in a hotel, each at ten yuan.

Summary: This involves the logical concept of stealing, because 2 yuan has counted the waiter in 9*3=27 (the actual hotel expenses of three people), plus the returned 3 yuan ***30 yuan.

This question was misunderstood because the questioner stole the concept. Starting from the payer, first, each of the three people takes out 10 yuan and returns it to Party A, Party B and Party C, that is, 1 yuan. Now each of them has 1 yuan * * 3, the rest of the waiters took 2 yuan, and then the shopkeeper charged 25% of the hotel fee, so 3+2+25=30.

Starting from the payee, the shopkeeper first charges 30 minus the returned 5 yuan, which happens to be 25 yuan. Finally, 9 yuan and 2 yuan have different concepts of money from different angles.

Math:

Mathematics is a subject that studies concepts such as quantity, structure, change, space and information. Mathematics is a universal means for human beings to strictly describe the abstract structure and mode of things, and can be applied to any problem in the real world. All mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science. Different mathematicians and philosophers have a series of views on the exact scope and definition of mathematics.

Three people go to a hotel, how to solve the problem?

The money stolen from 2 yuan by the waiter has been included, which means that as soon as they hand it over to 27 yuan, 25 yuan gives it to the boss, and 2 yuan is kept by the waiter. So it should be 27 yuan and 3 yuan, who will pay them back, which is exactly 30.

Ask a brain teaser. Three people in a hotel, 30 yuan.

Analysis: In fact, there is no problem of losing one yuan in this problem. The correct way of thinking is this. First, the boss started to take 30 yuan, and then he returned to 5 yuan, which means that he only took 25 yuan in the end; Then the waiter took 2 yuan; They each got 1 yuan. Total * * is1+1+1+2+25 = 30 yuan. That's right.

Or you can think of it this way. At first, each of them paid 10 yuan, and finally each of them got 1 yuan, which is equivalent to each of them only paying 9 yuan, and a * * * is 3×9=27 yuan, and then the waiter gave them 3 yuan money, so the total * * * is 27+3=30 yuan.

Both of the above ideas are correct. But as mentioned in the title, the 27 yuan they have been paying should be added to the 3 yuan money returned to them, which has nothing to do with the 2 yuan money pocketed by the waiter, so it can't be added together.

The problem of three people staying in a hotel

In fact, three people only used 30-3=27.

By the end of 20 12, there were nearly 3.3 million accommodation and catering enterprises in China, with annual operating income exceeding 2 trillion, accounting for about 5% of the GDP of that year. 20 1 1 year, the national catering revenue was 2,054.3 billion yuan, up by 16.9% year-on-year, with more than 22 million employees.

In terms of accommodation industry, there are more than 280,000 accommodation enterprises in China, of which the number of enterprises above designated size in the accommodation industry has reached 6,543,800+6,000, an increase of 8.4% year-on-year; Operating income was 2 184 billion yuan, a year-on-year increase of 23.3%; Operating profit was 654.38+060.3 billion yuan, up 22% year-on-year. The slowdown in the growth rate of the industry shows that the era of high profits in previous years has passed and entered the era of low profits.

China leads the rapid development of tourism and hotel industry in Asia, and the growth momentum of business and leisure income is strong. Compared with first-tier cities, the price of hotel rooms in second-and third-tier cities in China has increased greatly. With the opening of new hotels in second-and third-tier cities, the government has invested in the construction of new transportation facilities, which will further promote the steady growth of hotel room prices in China.

Chinese and foreign hotel brands continue to expand their business maps, and the balance between supply and demand of hotels in the future will be a topic of great concern. The proportion of all kinds of chain hotels in the world is: luxury 5%, high-grade 30%, middle-grade 37%, economical 20% and applicable 8%. However, affordable hotels only account for 28% and have great development potential.

Three people stayed in the hotel, and each person paid 10 yuan * * * plan: 30 yuan. The next day, the boss said he would give them a 5% discount.

Tip: Don't walk around! This is a question of account balance.

To explain by mathematics is to find the equivalence relation. There are many, just to give an example:

1, A/R and A/P balance, that is, A/R = A/P.

10×3=30

Or (10- 1)×3+5-2=30.

2. Display the paid-in balance of the boss.

( 10- 1)×3-2=30-5

3. According to the balance of passenger expenditure.

( 10- 1)×3=30-5+2

Or 10×3-3=30-5+2.

4, according to "buddy" corruption.

( 10- 1)×3-(30-5)=2

The direct answer to your last question is the second one above.

That is, 27-2=30-5, (27+2 is meaningless)

mean

The meaning on the left is: passengers pay -man corruption = preferential price,

Left: Hotel receivables-preferential amount = preferential price.

I hope it helps you!
