Excuse me, 99% of the interview questions of BMW are wrong. Can you answer correctly? A person spends 8 yuan to buy a chicken and 9 yuan to sell it. Flowers1bought in 0 yuan,

Topic: interview questions of BMW company. 99% of people answered wrong. Can you answer correctly? A person spends 8 yuan to buy a chicken. 9 yuan sells it. 10 yuan repurchased, 1 1 yuan sold. How much did he earn?

1 yuan, for example, he only has 8 yuan. He spent 8 yuan to buy a chicken, and 9 yuan sold it, earning 9-8= 1 yuan. His current fund is 8+ 1=9 yuan. If you buy flowers 10 yuan back, you need to borrow 1 yuan. This is a misunderstanding of many people. You should pay back the money you borrowed. 1 1 yuan and then sell it, and earn110 =1yuan. So 8+ 1- 1+ 1=9 yuan.

9 yuan invested 1 yuan to make this transaction, and made a profit 1 yuan. He earned 1 1-9=2 in 9 yuan and 1 in 2 yuan. Didn't he earn 1 yuan?

If he has the capital of 10 yuan, he will invest in 8 yuan first and then 10 yuan. If he doesn't need to borrow, will he still invest 1 yuan?

The topic is ambiguous.

Is the cost the same for the first time in 8 yuan and later here in 9 yuan? Some people say that it's all their own money anyway. It's all the same. But I ask you, yesterday's meal and today's meal were all eaten in the stomach. Can that be counted together? Is it because I ate something today and I don't have to eat it tomorrow? It's all in your stomach anyway. So there is no solution to this problem.

There are four algorithms:

1, 9-8= 1,110 =1,1+ 1=2, so I finally earned 2 yuan.

2. At the beginning, there was only 8 yuan, and finally you had 1 1 yuan, so you earned 3 yuan;

3, the first sale, the hero lost 8 pieces, got a chicken, the second sale; The hero gets 9 pieces and loses a chicken; On the third sale, the hero lost 10 and got a chicken. In the fourth transaction, the hero got 1 1, and one chicken was missing, so the total GDP was 8+9+10+1= 38 yuan +4 chickens.

There are three transactions in the whole event. Let's take a look at the specific three times. The first transaction: 8 yuan buys, 9 yuan sells, and gains 1 yuan; The second transaction: 9 yuan sells, 10 yuan buys, and the profit is-1 yuan; The third transaction: 10 yuan buys, 1 1 yuan sells for profit 1 yuan; The whole process:1-1+1=1yuan, so the analysis shows that this person is a fool, because the last two transactions are equal to nothing.

After testing, the enterprise thinks that:

Answering the profit of 2 yuan is definitely an interview loser;

It is even more stupid to answer 3 yuan, because if you don't know what the additional cost is, you will definitely fail;

If you answer 1 yuan, congratulations, it is not within the scope of fools;

As a result, 3 yuan could have made a direct profit, but after three transactions, the total profit became 1 yuan. So the correct answer is: -2 yuan! Answer -2 yuan, congratulations! The interview was successful! ! ! Ordinary people choose the cost of 2 ~ ~ 8 quick money ~ ~ When they buy 9 quick money for the first time, the profit is a quick money ~ ~ But when they spend 10 to buy it quickly, then the cost of subtracting the profit and adding a quick money is the cost of 9 quick money ~ ~ When they buy it at 1 1, it is the profit of 2 quick money and 8 (cost)+. 38+00 10 cost profit and increased cost)-1 profit =9 (cost)1(final transaction price) -9 (cost) =2 profit, this kind of investment may fail ~ ~ ~ profiteers will choose/kloc-0. ~ You bought a chicken with 80,000 yuan from the bank ~ ~ You bought a chicken with 90,000 yuan and earned 1 10,000. ~ you have to ask the bank for 10 thousand yuan to buy it back ~ and then you lose 10 thousand yuan ~ ~ because you have increased. After that ~ ~ the chicken is still your chicken ~ ~ You earned 10,000 ~ ~ Then you bought 100,000 from 90,000 ~ ~ Originally you earned 10,000 ~ You posted 10,000 and bought it back ~ ~ Although you said that you later earned 10,000 ~ ~ But whose money you posted 10,000 was ~ ~ Your own cost. 8000 yuan earned 1065438+. The business of 38+00000 yuan earned10000 ~ ~1-1=1~ ~ This is the merchant's algorithm ~ ~ The correct answer should be -2 ~ ~ because if he doesn't buy it back, the direct economic benefit can be answered to 3 fast ~ ~. The accounting profit is two yuan, the first sales profit rate is 12.5%, and the second sales profit rate is 10%, which is not cost-effective. Why should I have earned three yuan, unless 8 yuan bought direct 1 1 and sold it! You can earn three dollars! Why buy 9 on 10 again? In fact, if the cost is controlled, it will be one yuan for the first time, three yuan for the second time, and four yuan for a * * *! The second time, the cost can be increased by two yuan, so the loss is two yuan. Conclusion: Cost control is very important. The answer is that 2 yuan's explanation of economics is this: the principle of economics is commodity value, and the pursuit is profit maximization. In 9 yuan, the chicken seller knew that he had lost money, because he later learned that the value of chicken could reach 1 1 yuan. According to the principle of maximizing normal interests, from 8 yuan to 1 1 yuan, 3 yuan should benefit. But in practice (the second transaction), he bought chicken from 10 yuan (increasing the unnecessary cost, 2 yuan), and finally sold it from 1 1 yuan, making a profit of 1 yuan (using accounting principles). In this process, his cost increased to 2 yuan (from 8 yuan to 10 yuan), and the cost expenditure was totally unnecessary. So the economic understanding is: 3 yuan should be available-actually available 1 yuan = lost 2 yuan. How can I count them all together? 8-9 =+1 9-10 =-11=+65438. Speaking of two pieces, why don't you consider the quick money repurchase of10, because What is really included in the calculation is 10- 1 1. A brief analysis of his business, with two business cycles, earned 2 yuan. The optimal scheme is: 8 yuan buys, 1 1 yuan sells, earns 3 yuan, and uses a trading cycle. The yield of one cycle is (8- 1 1)/8=37.5%. According to this rate of return, the two-cycle return is 8 *1.375 *1.375-8 = 7.125 yuan. In a word, he earned two yuan. -2 yuan This question is not about mathematical calculation ability, but about whether you can put "how to get the maximum profit" in the first place in economic activities, and it also tests whether you can define your position in the complicated trading process. Before solving the problem, first of all, it should be explained that the value of goods will change during the exchange process. Here we should consider the problem of cost accounting, that is to say, the cost of chicken is not static. (1) 8 yuan When I first bought it, the cost of chicken was 8 yuan for him (and for people who would deal with him later). Then it was sold in 9 yuan, at which time it earned 1 yuan. There is no doubt that this is obvious. (2) Please note that the following sentence is the key: the person who bought the chicken (we call it B) spent 9 yuan money to buy the chicken, so at this time, for B (and those who will trade with B in the future), the cost of the chicken is 9 yuan money, just like when that person (we call it A) spent 8 yuan money to buy the chicken, the cost of the chicken was 8 yuan money. (3) At this time, Party A purchased the chicken from Party B at a cost of 10 yuan. If you think from the perspective of B, B sold the chicken bought by 9 yuan at 10 yuan, and B earned 1 yuan, which means A lost 1 yuan. (4) Now that the chicken in A's hand was bought by 10 yuan, the cost of chicken has risen to 10 yuan for A (and those who want to trade with A in the future). (5) Finally, A sold the chicken with the cost of 10 yuan to another person at the price of 1 1 yuan (just call it C), and earned 1 yuan as in (1). Then sum up: (1) Earn 1 yuan,+1; (3) Time deficit 1 yuan,-1; (5) Earn 1 yuan,+1. A * * *+1-1+1=1yuan. So it can be said that this guy A is crazy. After (me), he has earned 1 yuan. Steps (ii) to (v) are futile and inefficient. Let's take a look now. C has that chicken, and he spent 1 1 yuan on it, which means that the cost of chicken has now risen to 1 1 yuan. If A had sold his chicken to C at the price of 1 1 yuan at the cost of 8 yuan, it could have reached the present situation, that is, A could have earned 3 yuan, but now it only earned 1 yuan, so in the whole process, A actually lost 2 yuan (that is, it did not get the profit it should have earned, which is also a disguised loss). How simple! Spent 18, sold 20 20- 18=2! ! ! ! Obviously, two answers are given, that is, negative two. . . There are so many people counting. . . People don't take math, they take economic benefits. Without the continuous increase in the previous period, will someone buy chickens with 1 1? Just like the stock market, if 5 yuan buys, 10 yuan can sell? When the chicken rises to 1 1, the expectation disappears. Don't wait for the loss? He also said that he earned less. That's interesting. According to this, everyone who stocks stocks should die. According to an interview with BMW, there is no such problem at all ... bullshit, and economic principles! "Without the continuous increase in the previous period, some people will use 1 1 to buy chickens? Just like the stock market. " I think this sentence is not entirely correct. God knows how much you spent on this chicken when you sold it. Besides, even if the cost of chicken keeps rising, it is artificially fried. Is chicken really valuable? Don't take chicken ~ I want to answer that according to the landlord's theory, the loss should also be 1. The landlord's point of view is that the interests of others are their own losses. Do you think you are the time for God to roll the dice? I don't think this problem should be earning, but losing. Now society is on the rise. The consumption between buying this chicken and selling this chicken is far greater than the profit. I'm just a soy sauce maker. Only personal opinions are expressed here. Of course, I will also adopt what some people said before, just as a summary. For the record, I'm just a young man who didn't graduate from junior high school. First of all, no matter what this topic means, whether it is an interview question of BMW or not, when we do any topic, we must read it clearly first, right? This should be said by a primary school teacher. As for the deeper meaning of this question, I will talk about it later. Let's do it first. I think it's easy to do the problem, right? Selling 9 yuan at 8 yuan's price must have earned 1 yuan, so now I have 9 yuan, and then I bought it back with 10 yuan, which obviously lost 1 yuan. Finally, I sold it with 1 1 yuan, which obviously earned me and 2 yuan. There is certainly no need to write a mathematical format in the middle, right? A problem that everyone can think of with their feet. Then let's analyze whether this friend made a profit or lost. First, he bought a chicken with 8 yuan's money. At this time, his capital can be said to be 8 yuan, and then he sold it for 9 yuan. He earned 1 yuan, and then he bought it back with 10 yuan. It must be a loss. With his capital and previous profits, he wants to buy the chicken back with 1 yuan, so this should be. Finally, he sold the chicken for 1 1 yuan. This is also very simple, that is, he subtracted the capital 9 yuan from the last sold 1 1 yuan, so he earned 2 yuan. Maybe I talk too much nonsense, I can't help it, and I have no culture. I just want to say that no matter what business you do, one thing will never change, and that is, when you get it back, you don't have that much money. It must be a loss. Everyone knows this. As for why you can't get it back, I won't discuss it here. Let's talk about the deeper meaning of this problem. The landlord said that this question is to test whether you can put "how to get the maximum profit" in the first place in economic activities. A friend said very well, and I agree with him very much, that is, without the continuous increase in the previous period, it is difficult for your 8-yuan chicken to rise to that high at once, of course, it is not very difficult, depending on your own skills, and anyway, the first price can never be the highest. Even if you sell 1 1 yuan for the first time, you may earn 15 yuan in 3 yuan, 20 yuan and even 30 yuan, because it is easy to give people the illusion that this chicken will appreciate for the first time. Of course, chickens are definitely hard to appreciate in real life. So if it goes higher and higher, how do you sell it when you buy it for the last time? Will others be so optimistic? Of course, this is only a hypothesis, and there is nothing practical to compare. So, to put it simply, this man earned, and he also earned 2 yuan. If you think too much, your brain may not be enough. Oh, at least I'm not enough. All I know is that if I get more money back than I take out, I will make money. This is inevitable.
