A chicken is bought in 8 yuan and sold in 9 yuan; Buy 10 yuan and sell 1 1 yuan. How much money did you make?

The answer is 1, 9-8= 1,1-1,1 = 2, so you 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 see which 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)+. Principal profit and increased cost)-1 profit =9 (cost)1(final transaction price) -9 (cost) =2 profit, and this kind of investment may fail ~ ~ ~ profiteers will choose1~ ~ and make a profit first and then buy back/kloc. ~ 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. ~ Chicken is still your chicken ~ ~ You earned 1 10,000 yuan ~ ~ Then you bought 1 10,000 yuan from 90,000 yuan ~ ~ You originally earned 1 10,000 yuan ~ You earned 1 10,000 yuan and bought it back ~ ~ Although you later earned 1 10,000 yuan. The selling profit of ~ ~1-1+1=1~ This is the merchant's algorithm ~ ~ The correct answer should be -2 ~ ~ because if he doesn't buy back ~ ~ the direct economic benefit can be answered as soon as 3 ~ ~ but the profit caused by a person's business is 65433 ~.
