The numbers turn sharply 99 percent will not

Lou is correct, 27 yuan is the money paid by three people, 2 yuan is part of the money returned, the two cannot be added together, this is the title is misleading Lou is to re-analyze the problem, but did not solve the actual contradiction. The analysis on the 5th floor was wrong, the three people originally paid 30 yuan, and later returned 3 yuan, 30-3 = 27, and the three actually paid 27 yuan.

Take 30 yuan for analysis: 25 (shopkeeper) + 2 (small two) + 3 (returned) = 30 (yuan) store small return.

The main two also.

At the beginning, the consumption of 3 people was 25 yuan, that is, 25 3 yuan per person, and later 1 yuan was returned per person, then, each person spent (25 3) + 1 yuan.

Multiply each person's expenses by 3, which is the total accommodation fee for three people. i.e.: [(25 3)+1] 3 28.

plus the 2 yuan that the shopkeeper took, 28 2 30.

It's a reunion, right? Hehe.

Each guest spent 10 yuan to stay, and took back 1 yuan, that is, each person took out 9 yuan, 3 9 yuan is 27 yuan, here is right, but why use 27 plus 2 later, this is a problem, three people each out of 9 yuan, a total of 27 yuan, of which 25 yuan in the owner's place, 2 yuan in the second place, 25 plus 2 just 27 is not 27,

The shopkeeper returned 5 yuan, and there was 25 yuan left, and Xiao Er took 2 yuan of it, and 5 yuan was left, so the 3 people paid 28 yuan together.

plus the 2 yuan of the primary two is 30 yuan.

And 3 people paid a total of 27 yuan for 9 yuan, of which 2 yuan was taken away by Xiao Er, and the 2 yuan taken by Xiao Er was actually in 27 yuan, so it was 25 yuan.

The answer to the 5 6 7 9 floors under the summary is correct.

This question is misleading.

In fact, the three people who lived in the hotel only paid 27 yuan, and the so-called 30 yuan was to add the three yuan returned by each person, which added up to 30 yuan. In the question, 27 yuan plus the 2 yuan of the shopkeeper became 29 yuan, but in fact, the 2 yuan of the shopkeeper was included in the 27 yuan.

In fact, 30 = 25 + 2 + 3 * 1

So no one took that 1 yuan at all.

The total payment of 3 9 yuan is 27 yuan, of which 2 yuan was taken away by Xiao Er, and the 2 yuan taken by Xiao Er was actually in 27 yuan.

Lie! The house obviously used 25 yuan, plus the returned 3 yuan, plus the 2 yuan in the small second bag, just 30 yuan!

That one yuan is not less, but the algorithm is wrong.

Isn't it at the shopkeeper's?

It's that complicated.

Dizzy, who knows

Even if a cat took it and put it (snickering).

This problem has been around for a long time, and it comes in many forms.

You mean 99 people are in elementary school
