There are four algorithms:
1, 9-8= 1,110 =1,1+ 1=2, so I finally earned 2 yuan.
2. At first there was only 8 yuan, and finally you had 1 1 yuan.
So it is to earn 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. On the fourth sale, the hero got 1 1 and lost a chicken.
So the total GDp (gross domestic product) is 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, the interview was successful! ! !
A strong answer:
The total profit should be two yuan.
I think the total profit should be two yuan. (If it comes out, it will come out. Obviously, it is so complicated not to get involved in the muddy water of that enterprise. )
First of all, we must clarify two basic points:
1, the calculation method of profit is the difference between sales and expenses (including production expenses, management expenses and financial expenses);
2. Profit is ultimately money.
Therefore, the above two behaviors of buying chickens should be calculated independently. Two buying and selling behaviors are two complete profit production processes, and each process produces a gross profit of one yuan.
Selling the chicken and buying it back is a loss, which violates the two basic principles mentioned above. Chicken, like industrial materials, land and water and electricity, cannot be used as the final calculation method of profit. When you buy things with money, you must carry out the sales process, recover the currency and complete a currency cycle before you can calculate the profit. Chicken, originally sold in 9 yuan, has completed the currency cycle. When I bought chicken 10 yuan for the second time, the original profit 1 yuan was not lost, not to mention 9- 10 =- 1 yuan, but lost 1 yuan, just starting a profit production process again, which had nothing to do with 8 yuan and 9 yuan for the first time.
If I later find out that this chicken is a rare species in space, I will buy it back at 1 1,000 yuan, sell it at 1, and earn 500 yuan for the second time. According to the above algorithm (1 1 yuan sold 1000 yuan bought back, losing 989 yuan), isn't it a big loss?
Therefore, some enterprises have a lot of book profits, in fact, they are all on accounts receivable, so they are overwhelmed and closed down.
There is a saying in financial circles that "cash is king". Without money, it is very dangerous to manage materials, commodities and land with much worse liquidity than money as money.
Another powerful answer:
The first transaction: -8 (cost)
The second transaction: -8+9= 1 (profit plus cost)-at this time, there is the cost of 9 yuan.
The third transaction:-8+9-1 0 =-9 (the cost of 9 yuan, plus the cost of1yuan, the cost at this time is 10 yuan).
The fourth transaction:-8+9-10+1 = 2 (but the previous cost was10 yuan, and it was sold to 1 1 yuan, only earning1.
Cost accounting:
8 yuan earned back the cost in the second transaction, with a profit of 1 yuan.
The cost of the third transaction is 10 yuan, which was bought with the 9 yuan obtained from the second transaction (note that the cost of the first transaction was also included, adding 1 yuan) and 1 yuan.
The fourth transaction is to sell 1 1 yuan, which means that the profit based on 8 yuan cost is 3 yuan, but the profit based on 10 yuan cost is 1 yuan.
There are stronger ones! !
Return on investment = net income/total investment
= ( 1 1 - 8 ) / 8 = 37.5%
The first transaction:
Return on investment = (9-8)/8 =12.5% = I1.
Net present value = (cash inflow-cash outflow) *[( 1+ discount rate)-1]
=(9-8)*[( 1+37.5%)^- 1]= 1 * 0.7273 = 0.7273 = NPV 1 & lt； 0
Losing money business
The second transaction:
Return on investment = (11-10)/10 =10% = I2.
Net present value = (11-10) * 0.7273 = 0.7273 = npv2.
This guy tripped in the same place twice.
Internal rate of return = I1+[NPV1(| NPV2 |+NPV1|)] * (I2-I1)
= 12.5% + [ 0.7273 / ( 0.7273 + 0.7273 ) ] * ( 10% - 12.5% )
= 1 1.25% = IRR & lt； 37.5%
The economic impact is unacceptable.
Net income = 9+11-[8 * (1+37.5%)+10 * (1+37.5%)]
= 20 - 24.75 = -4.75
He earned -4.75 yuan.
Contribution to GDP:
"The total GDp (gross domestic product) is 8+9+10+1= 38 yuan +4 chickens." Let's stop ERp and go home and sell chickens. Maybe China's GDp will be the first in the world next year.
There used to be two economists, and Lu Yu was a piece of shit.
A said to B, "You eat this shit and I'll give you 50 million."
B think about it, eating shit is worth 50 million! So I held my nose and ate the shit.
A gave B 5000 million, and the more I think about it, the more depressed I get-50 million is gone, no, I have to find a way to get it back. Not long after, I met another shit, so A said, "I ate this shit and you gave me 50 million."
B ate dog shit and his stomach was upset. He thought, I ate shit and wanted you to taste it.
So the two hit it off, A ate shit, and B returned 50 million to A. ..
As they walked, the more they thought about it, the more wrong they were: What kind of mental illness have we got today? One of us ate a piece of shit. ...................................................................................................................................
After listening to their narrative, Wu Lao said, "Congratulations, you have contributed 1 100 million yuan to the GDp growth of the motherland." .
