Hello 1 A man bought a chicken for 8 bucks

2 pieces Don't look at so many numbers.

I actually bought and sold 2 times, and I made a dollar each time.

Earned $2.

The first time I made 1 yuan, the second time I made another 1 yuan, that is, a total of 2 yuan.

Eight yuan to buy nine yuan to sell, ten yuan to buy back eleven yuan to sell, you can get:

Equation: 9-8+11-10=2

First of all, people only asked how much money you made in the end, didn't ask how much you could have sold, how much money did you make less, the original cost was only 8 yuan to buy a chicken, I sold it for 9 yuan, and then I saw a chicken, I borrowed 1 yuan from a friend, added up to 10 yuan and bought a chicken, and finally sold 11 yuan, I had 11 yuan left in hand, I returned the 1 yuan I just borrowed from a friend, I still have 10 yuan left, at first I only had 8 yuan, now I have 10 yuan, and finally 10-8=2, so in the end I earned 2 yuan, It's because people who think they're smart make things complicated, and elementary school students can count them.

Originally, there were eight yuan, nine yuan were sold, one yuan was earned, ten yuan **, not counting chickens, nine yuan was lost, eleven pieces sold the chickens, -9 + 11 = 2 yuan earned two yuan.

The questions that elementary school students can calculate are confused by those self-righteous smart people, who ask how much money they make in the end, and they don't ask how much money they make less. First of all, the cost of eight yuan, bought a chicken, I sold it for nine yuan, and then I saw a chicken, I borrowed one yuan from others, made up ten yuan and bought a chicken, and then sold it for 11 yuan, that is, in the end, I had 11 yuan left in my hand, and I returned the one yuan borrowed by others before, I still had 10 yuan, and I only had 8 yuan at the beginning, so 10-8=2, and finally I earned two yuan. This is the final answer, people don't ask the market could have made more money, but how much money you made less, that is, to ask you how much money you made in the end, so you ended up earning two yuan, a question that elementary school students will have.

I earned two yuan, because I made a profit of 1 yuan for the first time, and bought a chicken for 10 yuan, which is equivalent to another 9 yuan and sold for 11 yuan.

Selling, picking up yuan and **, eleven yuan and selling, this person earns a total of a few yuan.

You can actually try it and you're 2 bucks more than the original.

Pit 3! He lost $2. The reason - just hit it!

In this question, you must first calculate how much money you made from the first transaction, and then count the limbs and smile and calculate how much money you spent 10 yuan to buy it back.

Solution: 9-8=1 (yuan).

I made 1 yuan on the first sale.

1 (included in the Yuan calendar).

Answer: This person is equivalent to spending 1 yuan more to buy back this chicken.

Spend $8 to buy a chicken and sell it for $9. A dollar was made here; 10 yuan to buy back the ridge, 11 yuan in the base of the field did not go out. A dollar was also made here. 1+1=2 yuan.

The explanation of economics goes like this:

The principle of economics is the value of commodities, and the pursuit of profit maximization.

The man knew that he had lost money after selling the chicken for 9 yuan, because he later understood that the value of the chicken could reach 11 yuan.

According to the normal principle of profit maximization, from 8 yuan to 11 yuan, a profit of 3 yuan should be made.

However, in the actual operation (i.e., the second transaction), he sold it from 10 yuan ** chicken (increased unnecessary cost, 2 yuan), and finally sold it for 11 yuan, making a profit of 1 yuan (using accounting principles).

In the process, his cost increased by 2 yuan (from 8 yuan to 10 yuan), and the cost expenditure was completely unnecessary.

So in economics, the understanding is: the 3 yuan that should be able to be obtained, the 1 yuan that actually gets is lost, and the 2 yuan.

I don't know if you understand my explanation, but it's easy to understand if you remember to maximize benefits.

I can't reply to your message, I'll explain it to you here.

((It's actually 2 pieces, which is not wrong.)

But this is not the case with the explanation of economics, as I said earlier, profit maximization is the basis of the explanation of problems in economics.

Let me tell you this: What you can buy for 8 yuan, you buy it for 10 yuan, are you at a loss?

What can be sold for 11 yuan, you sell it for 9 yuan, are you losing money?

In the end, compared with the same item, in this process, he lost a total of 4 yuan, earned 2 yuan, and finally lost 2 yuan.

Profit maximization is not achieved. ))

11-8=3 So the first time you should earn 3 yuan, the second time you earn 1 yuan, so you should earn 4 yuan, but you only earn 2 yuan, so you lose 2 yuan, but if you count the first purchase price is 8 yuan, the second time you buy it is expensive, so you lose 4 yuan.

Negative 2 yuan is calculated like this, there is only 8 yuan in hand, then 8 yuan is bought, 9 yuan is sold, 1 yuan is earned, and 9 yuan is in hand; 10 yuan to buy, 9 yuan needs to be pasted 1 yuan to have 10 yuan, 11 yuan to sell, earn 1 yuan, just to protect the capital, still 9 yuan in hand. So according to the maximization of benefits, the original 8 yuan can be sold for 11 yuan, earn 3 yuan, but you only earn 1 yuan, from the business perspective of corporate profitability, you do not earn 3 yuan, is a loss of 2 yuan.

It's because you can sell it for 8 yuan for 11 yuan, but you buy it for 10 yuan, so you lose 2 yuan.

The total income of the two times was 20 yuan, and the investment was 18 yuan. 20-18=2 That's how I understand it.

To put it simply; The first 'buying' earns 1 yuan;

The second 'buy', earn 1 yuan.

Earn a total of $2.

8+4=12 total cost.

7-4=3 fees earned for the first time.

12-3=9 to profit expense.

11-9=2 Fees actually earned.

Many people have been misled about this question, the question is how much money they made, not how much money they made less, or how much money they could have made, so they were all interfered with by two transactions, and they didn't care about him 8 into 9 throws, 10 into 11 throws! 9 throws and 10 into is the process, you don't need to count it in, you just need to remember, you went out and took 8 yuan! Enter the door hand 11 fast!

How much money do you say you made today? Speculation **** t+0 is this logic, for example, you open a position for 10,000 yuan, buy multiple **, make money and lose money, and finally sell at the same time (in reality, you can't ** and sell at the same time, because you have to do the bottom cost, I just take this as an analogy) to see how much your 10,000 becomes, if it's 13,000 congratulations! Profit 3000!

If it's 8000! Then you will lose 2000, and you don't need to calculate how much the ** ticket in the middle has earned, and how much the ** ticket has lost! That's too tiring!

Just look at how much your account changes from 10,000! This question is 8 blocks to 11 pieces! That's a profit of 3 yuan!

In the middle is the process! It is not the result!

The protagonist incurs two costs of the original cost of 8 yuan, and the cost of generating again is 10 yuan, and the cost of 8 yuan earns 1 yuan, and 10 yuan earns 1 yuan.

To sum up: the cost of 8 yuan and 10 yuan cost each earn 1 yuan, and the income is 2 yuan.

The meaning of earning and the meaning of earning should be clear.

The same chicken incurs two costs in front of the protagonist, each earning 1 yuan each.

As a result, "the cost is 8 yuan and 10 yuan each, and 1 yuan is earned", so it is concluded that "1 yuan and 1 yuan are earned."

This problem earns two yuan according to mathematics and one yuan according to economics, but those who originally earned 3 yuan can only earn one yuan now, so they lose 2 yuan. But in reality, the real money to trade is actually to make two dollars, why the economic society is considered to lose two dollars. What's the secret?

8 = 1, 11-10 = 1, 1 + 1 = 2, so in the end earn 2 yuan.

2. At first, there are only 8 yuan, and in the end you have 11 yuan, so you earn 3 yuan;

3. The first time to buy and sell, the protagonist loses 8 yuan, gets a chicken, and buys and sells for the second time; The protagonist gains 9 pieces and loses a chicken; The third time he buys and sells, the protagonist loses 10 yuan and gets a chicken; In the fourth sale, the protagonist gets 11 pieces and loses a chicken.

So the entire GDP (gross domestic product) generated is 8 9 10 11 38 yuan for 4 chickens.

4. There are 3 transactions in the whole event, let's take a look at which 3 are the specifics?

The first transaction: buy for $8, sell for $9, profit $1;

The second transaction: sell for 9 yuan, buy for 10 yuan, profit -1 yuan;

The third transaction: 10 yuan to buy, 11 yuan to sell profit 1 yuan;

The whole process: 1-1+1=1 yuan.

So the analysis shows that this person is a fool, because the last two transactions are equivalent to doing it in vain.

After testing, the enterprise believes that:

If the profit is 2 yuan, it must be a failure in the interview;

3 yuan is even more stupid, because I don't know what the additional cost is, and it must be a failure;

1 yuan, congratulations, you don't belong to the scope of fools;

The result is: he could have earned 3 yuan directly, but after 3 transactions, the total profit became 1 yuan.

So the correct answer is: -2 yuan!

Interviews alone, it's just that you make two dollars, and anyone can figure it out, and you really wouldn't take nine dollars to buy it.

I think the correct answer should be to earn two dollars, and one less.

This person bought for 8 yuan and sold it for 9 yuan = earned a dollar.

Sold for 9 yuan for 10 yuan and bought back = lost a piece.

10 yuan to buy, 11 yuan to sell = earned a piece.

I don't think it's right to do this with 1-1+1=1 (saying that if you lose two yuan, you may count it as 8 yuan, and buy 11 directly to earn 3 yuan, because you don't buy it like this, so you can count it less first, and it is expressed in plural.) Then -3-1=-2).

It should be calculated like -8+9- (10)+11=2 pieces (if you don't earn it, it may be calculated like this (-8+9)-(10+11)=0).

Mine is -8 + 9 (-10) + 11 = 2

If you buy it directly for 8 yuan, sell it for 11 yuan and earn 3 yuan directly.

I was supposed to earn 3 yuan, but now I only earn 2 yuan, so I earn 2 yuan, and I earn one less.

I think it's not enough to say -3, -8, -9).

Is it the problem of losing two bucks?

Maximize economic benefits.

8 yuan to buy chicken is the lowest price, 11 yuan to sell chicken is the most.

Then the biggest profit he made from selling chickens twice was 6 yuan.

And he only earned 2 yuan.

So he also earned 4 yuan less.

So he lost $4.

This question lacks premise assumptions, most of them will have different calculation results under different premises, and in the interview, you should ask the examiner about the premise to show your thoroughness.

The assumptions that come to mind at the moment are whether there is sufficient information about the market, whether there is sufficient freedom of trading, whether the person's funds are abundant.

And so on and so forth. If he can't get the information, he can only sell for 9 yuan for the first time, and he will not lose money on his first transaction, he may not be free to buy and sell, and he may start with only 8 yuan, the first time he earns one yuan, and the second time he has to borrow one yuan, what I want to express is that different assumptions will have different answers, and the key is to look at thinking.

This person earned 2

9 Whoever buys chickens earns 1

The 5th floor is too powerful, but I didn't understand it.

Earned, the same reason.

$2. It can be seen as two different trades.

Earn $1 each time.

This question is an interview question for a well-known foreign commercial company, and their requirement is to see if you can create the maximum profit for the company, and you can buy something that could have been bought for 8 yuan, but you bought it for 10 yuan, is it a loss of 2 yuan? What could have been sold for 11 dollars, but it was sold for 9 yuan, did it lose 2 yuan? A total loss of 4 yuan and the income is 2 yuan -4 + 2 = -2 is not a loss of 2 yuan If you buy 8 yuan directly and sell 11 yuan, not only save the steps in the process, but also directly earn 3 yuan.

1. The actual situation only focuses on the results of the income, without considering the details, and he earns two yuan. Reason: -8+9-10+11=2

2. If he sells for 11 yuan for the first time, 11-8=3, he can earn 3 yuan, but the actual situation is that he only earns 2 yuan.

He paid 1 yuan for his ignorance of the market.

In fact, it can be calculated in the simplest and stupidest way:

If A has 15 yuan, first he spends 8 yuan to buy a chicken and then sells it to earn 9 yuan, then he has a total of 15-8+9=16

And then the same goes for it: 16-10+11=17

So he earned $2!

But that's not the end of the story.

If A does not resell these few times, but buys 8 yuan, and then sells it directly when ** reaches 11 yuan, then he will earn: 15-8 + 11 = 18, so he will earn 3 yuan, but because he only earned 2 yuan by taking the first method, it is equivalent to not earning what should be earned, so the final answer is 1 yuan!

[Note] A person buys a chicken for 8 yuan and sells it for 9 yuan. I spent another 10 yuan to buy a [duck] and sold it for 11 yuan. How much did you earn???

8 yuan to buy a chicken, 9 yuan to sell === earned 1 yuan 10 yuan to buy a duck, 11 yuan to sell === earned 1 yuan Summary: two businesses net 2 yuan!!

Two-year-olds get it. If you have to talk about the topic. Then a chicken that can earn (11-8) 3 yuan, and in the end only earns (1-1)2 yuan, the final result is.

Earned 1 buck less. There is no such thing as losing money!!

If you make less money, you lose money, you lose 1 dollar!
