A person bought a chicken for 8 yuan, sold it for 9 yuan, and bought it back for 10 yuan, 11 yuan

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?

[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!

No tax, earn $2 or lose $2.

Earning binary is mathematically speaking, this will count.

The loss of two yuan is calculated like this: this person can spend 8 yuan ** and sell it for 11 yuan, so he will earn 3 yuan; Then you can sell it for another 10 yuan** and 11 yuan, so that you can earn another 1 yuan. In this way, he could earn a total of 4 yuan, but he only earned 2 yuan, so he lost 2 yuan.

If the tax is calculated, uh, eighty percent will be compensated...

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.

It was 2 yuan, but he lost 1 yuan in terms of investment and profit.

It must be a loss ... I haven't counted the tax rate yet...

In terms of making money, I earned 2 yuan, but "originally: 9 yuan to buy 12 yuan to sell, and earn 3 yuan; 11 yuan to buy 12 yuan to sell, earn 1 yuan, a total of 4 yuan, now the income is less, equal to a loss.

This is the mathematical explanation: his initial cost is 8 yuan, 9 yuan is sold for 1 yuan, 10 yuan is bought, the cost is added 1 yuan, 11 yuan is sold, the total cost is 2 yuan, and the result is 11 yuan in hand, so he earns 2 yuan.

In terms of business: he could have sold it directly for 11 yuan, but he made 1 yuan, so it is equivalent to him losing 2 yuan. That is, he earned -2 yuan.

A: Earned 2 bucks.

Analysis: The landlord can think like this: Suppose you have 10 yuan on you.

1. I bought a chicken for 8 yuan, and now I have 10-8=2 yuan left.

I sold the chicken for money, and the money left on my body was 2 + 9 = 11 yuan.

3. Spend another 10 yuan to buy chickens, and the remaining money is 11-10=1 yuan.

After selling the chicken for a few dollars, there is 1 + 11 = 12 yuan left.

So, compared to the beginning, I made 12-10=2 dollars.

Hope landlord! Give it points! Hehe.

The answer is not right after earning two dollars, this question involves the opportunity cost of economics, and the person in the question is actually very unwise, he made a loss-making transaction and lost two dollars.

Hahaha, this person has an addiction to trading.

Don't talk about economics and what accounting statistics, no wonder Chinese like to be pyramid schemes so much, it turns out that they are all people who like to be smart and don't know how to see the essence clearly, you had 8 yuan in your pocket yesterday, as of this morning, no matter how many transactions you had yesterday or what behavior you cheated and deceived, anyway, you now have 11 yuan in your pocket, no matter how you calculate it, it is good to count it as a loss of 1 million, it is good to count it as a profit of 100 million, anyway, it is 11 yuan. Nothing more, nothing less. As for how you calculate, that's fooling others, unless you used to have 8 yuan, and now you only have 6 yuan, I will admit that you lost 2 yuan.

People who obviously have 11 yuan in their pockets and shout that they have lost money, do you think about their intentions? Isn't it just learning like this and learning to fool people? You don't look at those people who are so reasonable, you just say to him:

I will buy your chicken for 80,000 yuan, 90,000 yuan will be sold to you, 100,000 yuan will be bought back, 110,000 yuan will be sold to you, if I lose money, it is my own, I will return 10,000 yuan to you, and I will return 20,000 yuan to you. "Do you think they're willing to do that??

This question is not a question of how much he earns. He's looking at the way you look at the problem. A normal person earns 2 yuan.

The merchant earns $1. The investor earns -$2. Honest work and people who have to spend is -3 yuan.

Originally, if you can't eat it, you can sell it for 11 yuan, but you can sell it for 8 yuan. You can buy it for 8 yuan, but you buy it for 11 yuan, but no matter how you buy it, they can make your money). Earn 3 yuan is **.

The one that comes out of nothing can be printed). (Honest people don't have the qualifications and experience to make money with money).

There are such transactions in life. If the interval between two transactions is long, the price of goods and the cost of chickens rise, this may happen. It's impossible for you to still want to stock at the original cost price. So the answer should be to earn two bucks.

It's such a simple question, first of all, the chicken could be sold for 11 dollars, but at first he only sold it for 9 dollars, and here he lost 2 dollars.

And then, he could buy the chicken back for eight dollars, but then he used 10 dollars, and here he lost two dollars.

He bought 8 dollars, sold 9 dollars, made a dollar, bought 10 dollars, sold 11 dollars, made another dollar, and he made 2 dollars for trading here.

So he lost 2 yuan.

It's always a fake BMW Microsoft question. The German company is so rigorous. It's definitely $2.

Otherwise would you dare to drive a BMW's car. The mechanical structure inside does not work according to normal logic.

It doesn't matter how much money he makes or not, but at the very least, he gets the chicken.

From a marketing point of view, he lost two bucks.

Regardless of the intermediate transaction, just counting his first and last transactions, the principal of 8 yuan and the final profit of 11 net profit of 3 yuan, this is no problem.

But he traded four times.

The first time: the principal is 8 yuan, ** a chicken.

The second time: sell, earn 9 yuan, profit +1 yuan.

The third time: **, it costs 10 yuan, counting the 9 yuan he earned the second time, this time the profit is -1, this is no problem.

Fourth: Sell, earn $11, profit +1

In this case, the profit of the four transactions is: 1-1+1=1 after removing the excess trades, which would have earned 3 yuan, and finally becomes 1 yuan, and the cost is increased (two more transactions), so he loses.

It's not that I know what this question is trying to examine.

To put it simply, it's actually obvious that it's two transactions:

The first year: 8 buy 9 sell to earn a piece.

It's been a year (the second year).

Another 10 buy 11 sell to earn a piece.

In the past two years, I have made a total of two trades and made 2 yuan, so don't sell 9 and buy 10.

This is an interview question for a foreign company, telling you that the correct answer is 1 yuan, but the answer that the company wants is -2 yuan. According to the title, this person bought 8 yuan to sell 9 yuan, earned 1 yuan, and then bought 10 yuan, he lost 1 yuan, and sold 11 yuan and earned 1 yuan, so it is 1-1+1=1, let's assume that the principal of this person is 8 yuan, 8-8+9=9, at this time the principal is 9, and then 9-10+11=10, the topic ends here, that is, after the business is done, this person still has 10 yuan in his hand, minus the principal of 9 yuan, then he only earned 1 yuan, pay attention to the principal subtracted is 9 yuan instead of 8 yuan, After doing business three times to earn 1 yuan, then he lost 2 yuan.

A: Earned 2 bucks.

Analysis: The landlord can think like this: Suppose you have 10 yuan on you.

1. I bought a chicken for 8 yuan, and now I have 10-8=2 yuan left.

I sold the chicken for money, and the money left on my body was 2 + 9 = 11 yuan.

3. Spend another 10 yuan to buy chickens, and the remaining money is 11-10=1 yuan.

After selling the chicken for a few dollars, there is 1 + 11 = 12 yuan left.

So, compared to the beginning, I made 12-10=2 dollars.

I hope the landlord adopts! Give it points! Hehe.

I bought it for 8 yuan, sold it for 9 yuan, and earned 1 yuan.

I bought it for 10 yuan, sold it for 11 yuan, and earned another 1 yuan.

So it adds up to a total of two pieces.

He lost a lot, and if he had been buying for 8 yuan and selling for 11 yuan, he would have sent it early.

Don't talk about anything else I made 2 bucks. Simple, complicated, in fact, you have to use simple thinking.

This seems to be a company recruitment question, right? I remember the answer was a loss. Because it seems that he made two yuan, but if he bought 8 yuan at the beginning and sold 11 yuan, he could earn 3 yuan, so he made one less profit for the company, that is, he lost one yuan.

Brother, he did two businesses, that is, he bought the goods twice, and each time he made 1 yuan, a total of two yuan.

1. Earned two dollars.

2. 9 people use 27 buckets of water for 9 days.

3. 50-50-15-29=-44 yuan, the boss lost 44 yuan.

1. Earned two dollars.

2. 9 people use 27 buckets of water for 9 days.

Three, 15 50 29 94, the boss lost 94 yuan.
