8 yuan for something, others give 103, how to think about how much money to find?

The explanation of economics is this: economics.

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

The man lost $9 selling chickens because he later understood that chickens could be worth up to $11.

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

But in actual operation (only the second transaction) from 10 dollars to buy his chickens (added unnecessary fees 2 yuan), and finally 11 dollars to sell, a profit of 1 yuan (using accounting standards).

In the process, it costs 2 yuan (8 yuan to 10 yuan) to increase his fee, which is completely unnecessary.

So the understanding of economics is: 3 yuan that should be able to be received - 1 = 2 yuan that should be able to be received.

Loss, I don't know if you know anything about this explanation, but you remember to maximize the benefits of not knowing enough.

You can't reply to my email, here is an explanation for everyone.

(There's nothing wrong with the actual 2.)

Explaining economics is not like this, but, as I said, the greatest benefit is based on economic science to explain the problem.

To tell you the truth: 8 dollars can buy something, you buy 10, you are not.

11 of the loss of money can sell something, you nine sell, are you a loss?

In the final project comparison, in the process, the total loss of his income was four yuan, two yuan of income, and finally the loss of two dollars. Profit maximization is not realized. ））

103。。The last digit is 3 to 8, so borrow one digit forward, become 13 8 = 5, and then the first 10 becomes 9! And then there's 95.

Think about the fraction of 103 for 3 yuan, 8 yuan minus 3 yuan, and there are 100 yuan left. Someone else bought 5 yuan and gave 100 yuan, and should find 95 yuan.

From an economic point of view, the answer to losing 2 yuan is.

The market is not fixed, and you will lose 2 yuan according to the results? No one can control market changes. There is even a saying that if you earn less, you will lose?

I don't know what the concept of making or losing is According to the gross profit, I earned two yuan, and if I made less, I can only say that the brains of the academic school If you don't spend 10 yuan to buy chickens, you may not be able to sell them for 11 yuan**, and the first time you bought it for 8 yuan, and the second time you can only buy it for 10 yuan, according to the academic algorithm, this person will always lose.

Earned 2 yuan, 8 yuan bought, sold 9 yuan, and made a net profit.

Buy it for 10 yuan, sell it for 11 yuan, and earn a net piece.

Profit = Revenue - Cost.

That's profit.

Earn 1 yuan every time you start to make a move, and earn a total of 2 yuan twice.

It can be said that if A has a total of nine dollars, spend eight dollars to buy, nine dollars to sell, so that there are still ten dollars in his hand, ten dollars to buy, eleven dollars to sell, there are eleven dollars in his hand to remove the principal of nine dollars, and there are two dollars of profit left, and there is an estimate that the brain may be a little atrophied if A buys it for eight dollars, and sells it directly for eleven dollars, and originally earned three dollars and only earned one and lost two dollars, why don't you buy it for eight dollars, sell it for nine dollars, and then buy it for eight dollars, sell it for eleven dollars, and earn four dollars.

The first time I earned $1 The second time I earned $1.

Earned $2.

Suppose you are this person, suppose you originally had 9 yuan, first you bought a chicken for 8 yuan and sold it for 9 yuan, and now you have 10 yuan, and then you think it is not worth buying it back for 10 yuan, and then you sell it to another person for 11 yuan. Then you'll have 11 bucks. Finally, 11-9=2

It should be answered from the perspective of economics: he originally had eight yuan, 11 yuan was sold, and he could have made 3 yuan, but after this stage he only made 1 yuan, which is obviously a loss of 2 yuan.

From an economic point of view, the loss of two yuan is nonsense, the key sophistry is wrong, don't be too greedy, according to this calculation, the chicken finishing can be sold for 100 or even higher, not a loss? Obviously, it is a total of 2 yuan in two transactions, but it is actually counted as a profit of one yuan in three times, and it is also served, so what if the chicken is the same one, it is just a transaction intermediary.

Mathematically earn two bucks; I made one piece from economics, but I could have sold it directly for three yuan, so I lost two yuan.

8 yuan to buy nine yuan, earn one plus a piece, ten yuan is to accompany a dollar in the sale and sale.

$2. bai

We can count this as one.

du people's income and expenses, so that zhi avoids being stunned

The total amount of money spent by this person is 8 + 10 = 18 yuan, and the total amount of money he gets is 9 + 11 = 20 yuan, so this person earns 20-18 = 2 yuan.

Earn two dollars, you can copy the assumption that there is.

If you hit 10 yuan and spend 8 yuan, you still have 2 yuan left, and if you sell 9 yuan, it is 2 + 9 = 11, and if you buy it back for 10 yuan, it is 11-10 = 1, and the last 11 yuan is sold, it is 1 + 11 = 12, and if you originally had 10 yuan, you will make 12-10 = 2 yuan.

Then I'll change it:

A man has a chicken at home, and he sells it for 9 yuan, and then he thinks it's not worth it, so he buys it back for 10 yuan, and sells it for 11 yuan.

Ask him how much he earns?

There is an answer above that says minus 2 yuan, I don't think so, it's like ** and the house will change at any time, and it is called money when you earn it. Let's say that he loses, if he buys land next time, 800 million buys 900 million and sells it, is it a loss, I would rather lose me every day.

First he paid 8 yuan to buy, and then 9 yuan to sell, made 1 yuan and then 10 yuan to buy, from which he took out another 1 yuan on the basis of 8 yuan, bought it for 10 yuan, sold it for 11 yuan, in short, bought 9 yuan and sold it quickly for 11 yuan, and made 2 yuan.

It's up to you to recover.

My statement is simple and easy to understand. The first step is to buy a chicken for 8 yuan, sell it for 9 yuan, and make a dollar here.

The second step is to buy a chicken for 10 yuan and sell it for 11 yuan, and you will earn a dollar here. The first step earned a dollar, and the second part also earned a dollar, which is 1+1=2. Earned 2 bucks.

This shows that he didn't make or lose money, but only guaranteed 8 yuan.

I read the answer of the great god just now... It's so complicated, you can see it if you earn 1 yuan.

It's so simple to explain, but it doesn't have to be so complicated.

(Abstract -8=1,11-10=1,1+1=2, the copy is made at the end of 2 yuan.) bai

2. Initially only.

du 8 yuan, and in the end you have 11 yuan, so you can earn 3 yuan;

3. The first time I bought and sold dao, the protagonist lost 8 yuan, got a chicken, and bought and sold 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 yuan and loses a chicken, so the entire GDP (gross domestic product) generated is 8 9 10 11 38 yuan 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:

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!

The total profit should be $2.

Money spent: 8 + 10 = 18

Money sold: 9 + 11 = 20

Money earned: money sold - money spent.

So: 20-18=2

The low-intelligence children who say that they earn one yuan and have not graduated from elementary school are obviously two yuan.

When I was in the sixth grade of primary school, my math teacher asked us, and of course I was puzzled by the answers, as if there were three answers. The first is to earn 2 yuan, the second is to lose 1 yuan, and the third is to lose 4 yuan. It mainly depends on the angle of your understanding.

Personally, I think there are many more answers to this, depending on personal understanding.

This is an IBM exam question.

Mathematically speaking, he made two bucks. This person invested a total of 18 yuan, sold a total of 20 yuan, and made a total of 2 yuan.

However, IBM is not testing mathematical logic. It examines the question of profit in economic transactions. Before solving the problem, it is important to note that the value of commodities changes in the process of exchange.

The issue of cost accounting should be taken into account here, that is, the cost of chickens is not set in stone.

1.The first purchase of 8 yuan, the cost of the chicken for him (and for those who will trade with him in the future) is 8 yuan. Then sell it for $9, at this time you make $1, here it is obvious, there is no doubt.

2.Note that the next sentence is the key: the person who bought the chicken (we call it B) spent 9 yuan to buy the chicken, so at this time for B (and for the person who will trade with B in the future), the cost of the chicken is 9 yuan, just as the cost of the chicken was 8 yuan when the person (we call it A) spent 8 yuan to buy the chicken at the beginning.

3.At this time, A bought the chicken with a cost of 9 yuan from B for 10 yuan, if we think from B's point of view, it is B that sells the chicken bought for 9 yuan for 10 yuan, B earns 1 yuan, and relatively A loses 1 yuan.

4.Now the chicken in A's hand was bought back for 10 yuan, so for A (and for those who want to trade with A in the future), the cost of the chicken has risen to 10 yuan again.

5.In the end, A sold the chicken, which cost 10 yuan, to another person for 11 yuan (let's call it C), and made 1 yuan for the same reason as (I).

Finally, to sum up: the first time you earn 1 yuan, +1;The second time the loss of 1 yuan, -1;Earn $1 on the fourth time, +1. , from the cost change point of view, a total of +1-1+1=1 yuan.

Let's take a look at it now, the chicken is in C's hands, and he bought it for 11 yuan, which means that the cost of the chicken has risen to 11 yuan now. If A sold the chicken that cost 8 yuan in his hands to C for 11 yuan at the beginning, it would also be possible to achieve the current situation, that is, A could have earned 3 yuan, but now he only earns 1 yuan, so A actually lost 2 yuan in the whole process (that is, he did not get the profit he should have got, which is also a disguised loss).

Economically, it loses two dollars.

That's a total of one dollar.

At the beginning, he bought 9 yuan and sold it for a dollar, but then he spent 10 yuan to buy, which is equivalent to losing the 1 yuan he earned before to the cost of buying chickens later, and then sold it for 11 yuan, which is equivalent to making a dollar, if the chicken could have been sold for 11 yuan, he spent two times but only earned one, which means that he made a profit but made a loss, and he could sell it for 8 yuan and 11 yuan.

Subtracting the price at the end of the sale minus the price at the time of the first purchase equals the final profit.

11-8=3, so he actually earned $3.

It's a logical paradox.

He only made 1 dollar, which is only the final cost.

It's two pieces,,, and I borrowed eight pieces and sold them for nine dollars, and I made one piece. Later, I borrowed nine dollars to make ten dollars and sold them for eleven dollars! 11-9=2

Earn 2 bucks. This is a transaction that is bought and sold twice, earning 1 dollar each time.

（9-8）+（11-10）=2

Only count the difference between each buy and sell, and earn 2 yuan.

Eight dollars to buy nine dollars to sell a piece of money, nine dollars to sell ten dollars to buy a loss of a piece.

Ten dollars to buy, eleven dollars to sell, sell and earn a dollar.

In general, a piece was earned.

Mathematically earn 2 yuan, you could have earned 11-8 = 3 yuan and the second person earned 1 yuan.

Whatever bullshit economics you have, all I know is that I used to have 10 dollars, and it turned out to be 12 dollars.

If you have 18 yuan, and you buy fish for 8 yuan and sell it for 9 yuan, you now have 19 yuan in your hand. Then I bought the fish for ten dollars, and sold it for eleven dollars, and now I have twenty dollars in my hand, and of course you have earned it.

It doesn't have to be complicated.

Cost: 8+10

Sales: 9+11

Profit: Sales - Cost.

I don't need to tell you the answer.

Your logical mistake is to sell it for 9 yuan and buy it for 10 yuan, and you feel that you have lost money, but in fact, the value of the fish has changed, and the fish itself is worth 9 yuan, and now the value of the fish in your hand has become 10 yuan. So if you sell it for 9 yuan and buy it for 10 yuan, you don't lose money. This is a logical error.

8 yuan**9 yuan, sell it for a dollar, make a dollar, 10 yuan**, sell it for another dollar, make a total of two dollars.

If you lose 1 yuan, if you buy it directly for 8 yuan and sell it for 11 yuan, you will earn 3 yuan. In fact, he only earned 2 yuan, so he lost 1 yuan.

Earn two bucks.

Let's say you only have 8 pieces.

I bought a fish for 8 yuan and sold it at 9 yuan. I picked up a piece with someone else. Buy it for 10 yuan, sell it quickly for 11 yuan, and leave 10 yuan after repaying the borrowed 1 yuan.

Those count as a piece of earning. Just ask: 8 in, 8 out. How much do you earn by 10 yuan in and 11 yuan out? That's what makes a piece.
