Xiao Ming, why do you have two covers?

Question 1: Xiaoming, why are there two bottle caps?

This is really a very special situation

It's usually just a bottle cap.

You can stay as a souvenir.

Question 2: Xiaoming sells drinks, 5 yuan for a bottle, 4 caps for a bottle, 1 bottle for two empty bottles, and you only have 20 yuan. Theoretically, you buy four bottles 1.20 yuan. After drinking, there are four empty bottles and four lids;

2.4 Empty bottles are 2 bottles and 4 caps are 1 bottle. After drinking, there are 3 empty bottles and 3 caps.

3.2 Replace the empty bottles with 1 bottle, and there will be 2 empty bottles and 4 caps after drinking;

4.2 Empty bottles are 1 bottle, and 4 caps are 1 bottle. After drinking, there are 2 empty bottles and 2 caps.

8. Borrow 2 bottles. After drinking, there are 2 empty bottles and 4 lids. Replace two bottles and return them. Don't leave the bottles and lids.

So there are: 4+3+1+2+1+2+1+2 =16.

Question 3: Why does Xiaoming have two eyelids? . . . . Leak-proof and easy to twist, it is also a brand symbol. In order to leave a deeper impression. In fact, you should think about why people choose dual card dual standby mobile phones. I don't understand in an instant. Answer.

Your question is beside the point. I answered so many questions, which shows that my love is earth-shaking and extremely touching.

Question 4: Xiaoming, why are there two bottle caps? Xiaoming will have two bottle caps.

Because it is the wrong bottle cap.

Then I saw my bottle cap.

This is why there are two bottle caps.

Question 5: Xiao Ming's beverage promotion, buy four bottles and get one bottle, two bottle caps can also be changed, 20 yuan can drink 1.20 yuan buys four bottles, and after drinking, there are four empty bottles and four lids;

2.4 Empty bottles are 2 bottles and 4 caps are 1 bottle. After drinking, there are 3 empty bottles and 3 caps.

3.2 Replace the empty bottles with 1 bottle, and there will be 2 empty bottles and 4 caps after drinking;

4.2 Empty bottles are 1 bottle, and 4 caps are 1 bottle. After drinking, there are 2 empty bottles and 2 caps.

5.2 Replace the empty bottle with 1 bottle. After drinking, there will be 1 empty bottle and 3 caps.

6. Borrow 1 bottle. After drinking, there are 2 empty bottles and 4 lids. Change 2 bottles, return 1 bottle, and leave 1 bottle.

7. Borrow 1 bottle, drink 2 bottles, 2 empty bottles and 2 caps; Replace 1 bottle, with 2 bottle caps left;

8. Borrow 2 bottles. After drinking, there are 2 empty bottles and 4 lids. Replace two bottles and return them. Don't leave the bottles and lids.

So there are: 4+3+1+2+1+2+1+2 =16.

Question 6: 20 yuan Xiaoming has five yuan for a bottle, four caps for a bottle and two bottles for a bottle. Why can the total number actually be bottle cap 1.25 yuan, bottle 2.5 yuan and beverage itself 1.25 yuan? Therefore, 20 yuan can drink at most 20 ÷ 1.25 = 16 bottles.

Question 7: Xiaoming urged five yuan for a bottle with four lids or two empty bottles for one bottle. There are twenty yuan now. The theory is to drink at most 1.20 yuan buys four bottles. After drinking, there are four empty bottles and four caps.

2.4 Empty bottles are 2 bottles and 4 caps are 1 bottle. After drinking, there are 3 empty bottles and 3 caps.

3.2 Replace the empty bottles with 1 bottle, and there will be 2 empty bottles and 4 caps after drinking;

4.2 Empty bottles are 1 bottle, and 4 caps are 1 bottle. After drinking, there are 2 empty bottles and 2 caps.

6. Borrow 1 bottle. After drinking, there are 2 empty bottles and 4 lids. Change 2 bottles, return 1 bottle, and leave 1 bottle.

7. Borrow 1 bottle, drink 2 bottles, 2 empty bottles and 2 caps; Replace 1 bottle, with 2 bottle caps left;

8. Borrow 2 bottles. After drinking, there are 2 empty bottles and 4 lids. Replace two bottles and return them. Don't leave the bottles and lids.

So there are: 4+3+1+2+1+2+1+2 =16.

Question 8: Xiaoming is doing promotion. 5 yuan has one bottle, one bottle with two empty bottles and one bottle with four caps, and 20 yuan can buy at most 16 5 points. The first method: 5 yuan 1 bottle of wine, 1 bottle with four caps, one bottle with two bottles. The calculation method is: 1 bottle cap 5/4 = 66. 1 bottle of pure beer =5- 1.25-2.5= 1.25 yuan, so 20/ 1.25= 16 bottles of beer.

The second method: 20 yuan bought four bottles of beer and borrowed 12 bottles of wine, so he drank 16 bottles of beer altogether. After drinking, 16 changed the empty bottle to 8 bottles of beer, and 16 changed the bottle cap to 4 bottles of beer, so a total of 12 bottles of beer were returned. Ok, the total number of bottles to drink =4+ 12= 16 bottles of wine.

Question 9: I remember how Xiaoming's first lid was opened. I can just pull it out, or my nails are longer. Just try it.

Question 10: Xiaoming is having a big promotion. One bottle of 5 yuan, four bottle caps or two empty bottles can be exchanged for one bottle. Now I'll give you 20 yuan. Theoretically, 10 can drink a few bottles at most. Buy four bottles first, drink them, 1 bottle for cap, empty bottle for two bottles, and then drink them, so there are three caps, three empty bottles, and one empty bottle for another. Replace an empty bottle with one, drink three bottles with 1 empty bottle, borrow one bottle from the boss, drink four bottles with two empty bottles, return one bottle to the boss, drink one bottle with one empty bottle, borrow another bottle from the boss, have two empty bottles with two caps, return one empty bottle to the boss, keep two caps, borrow two bottles from the boss and drink four empty bottles with caps. However, it is estimated that Xiaoming's children's shoes will go to the hospital soon, and it is strange to drink 16 bottles.
