Count the money, and pick it up.

A: 51, 32, 17 respectively.

Note: My algorithm uses a one-dimensional equation, but even in elementary school, I have learned how to solve one-dimensional equations, so you can use it with confidence.

Analysis: 100 coins, a total of 2 yuan, that is, 200 cents, then the average face value of each coin is 2 cents.

So 1 and 5 points can be divided into groups one by one, so that the average face value is 2 points. Of course, it can be calculated that for every 3 1 points, there must be a 5 points, and at this time, the average face value in this group of 4 coins is (3*1+1*5) (3+1)=2 points.

Now we know that the total value of 2 points is 13 points more than that of 1 point, and we set 2 points and x pieces, so there are 2*x-13 pieces for 1 point, and 3 pieces for 5 points are (2*x-13). So column:

x+(2*x-13)+(2*x-13) 3=100 solves x=32, so there are 51 for 1 point and 17 for 5 points. The calculation check shows that there is no problem.

Let's take a look: 1 point x; 2 points y; 5 points z

Then: x+2y+5z=200

x+y+z=100

Since the total value of a 2-cent coin is 13 cents more than a 1-cent coin, so: 2y-x=13x=2y-13

Substitute to the above two formulas:

2y-13+2y+5z=200

2y-13+y+z=100

Get: 4y+5z=213

3y+z=113

It can be solved as: y=32 z=17

then x=100-32-17=51

So 1 point 51, 2 points 32, 5 points 17

Solution: Let 1 point have x, 2 points have y, and 5 points have z.

According to the title, there is.

x+y+z=100...1）

x+2y+5z=200...2）

2y-x=13...3）

Solution: x=51;y=32；z=17。

Let there be x, y, and z respectively, and a system of equations.

x+y+z=100 (pcs).

x+2y+5z=200 (min).

y-x=13

By substituting the third equation into the first two, it becomes a system of binary equations, which can be easily solved.

Let 1 point have x, 2 points y, and 5 points z, and the system of equations is.

x+y+z=100 (pcs).

x+2y+5z=200 (min).

2y-x=13

Solve x=51y=32z=17

x+y+z=100 (pcs).

x+2y+5z=200 (min).

2y-x=13

The third formula upstairs missed a 2

It's only two dollars, a waste of time.

The landlord above is right.

Picking up a lot of money means picking up other people's finances in areas that you don't own, and the financial amount is very large, which is called picking up a lot of money.

If you dream and pick up a lot of money, you are either a poor person who wants to live a rich life, or a person who works hard and can get a large amount of money right away.

If it is a reality and you have picked up a lot of money, you have to go to the owner, otherwise the owner will be in a hurry.

If it is a hard work, then the life situation will be more difficult, and the life will be relatively poor.

If the unemployed are picking up money, it is an auspicious sign that they will be able to find a job that suits their hearts in the near future. There are many situations for picking up money, and it needs to be analyzed according to the actual situation.

If you pick up a large amount of money, it means that you are in good financial fortune, although it is not a huge amount of money, and it is not without a small benefit.

Because a penny is money, we grew up saying "I was on the side of the road e68a8462616964757a686964616f31333431366365, picked up a penny and handed it to the policeman's uncle for .......""Pick up a penny" in the children's rhyme is a good memory for many of us. But now, when a penny is found on the ground, most passers-by ignore it or glance at it and leave, and no one stays and no one picks it up. Sometimes no one even asks for a dime on the ground, why is that?

In the eyes of economists, however, it is a manifestation of economic phenomena such as rising consumer incomes, currency depreciation, and declining purchasing power.

The enlightenment of the wealth tycoon's "penny" wealth concept

It is said that although Rockefeller, the "oil king" of the United States, had a huge amount of wealth, he had to record all kinds of expenses, even the three-cent stamps. Therefore, his ledger never departed from him. It was found that he remembered every one of his books clearly.

It is this "trick" that allows him to always accurately grasp the data of costs and expenses, sales and profits when running an oil company.

The story of Li Ka-shing, the richest man in China, is also widely circulated. It is said that one morning, Li Ka-shing came out of his home, and the moment he stepped through the car door, a one-yuan coin fell from his clothes pocket and fell to the ground, rolling into a nearby sewer. Li Ka-shing asked the staff to pry open the sewer cover and find the yuan.

Then he took out 100 yuan and handed it to the staff, thanking him for helping him find it! Spending 100 yuan to get back 1 yuan, many people are puzzled. Li Ka-shing believes that for 1 yuan, no matter how much money it is, it represents wealth; And the staff helped him find a dollar, and he deserved to be paid.

In Yiwu, Zhejiang, there are still many people who are "picking up" 1 penny, starting with small profits and quick sales by only earning 1 penny, known as "ant merchants". The secret of their money-making is to open factories from house to house, minimize costs, and only earn 1 cent per item. It is this inconspicuous one-cent profit that has cultivated countless millionaires and multimillionaires.

They calculated: a pair of socks earns 1 cent, and an ordinary stall sells 700,000 to 800,000 pairs of socks every month, and there is a profit of 7,000 yuan to 8,000 yuan, and in a year, there is nearly 100,000 yuan.

For the attitude of 1 cent of wealth, perhaps in today's rise of entrepreneurship, there is still something worth thinking about.

I think it's impossible to throw money around and pick it up at will, and it's still valuable.

It is to maintain the habit of thrift and thrift, and every penny is money.

Diligence and thrift are the traditional virtues of the Chinese nation, in order not to waste national resources.

Maybe it's because it's still money, so people usually pick it up.

Diligence and thrift are the traditional virtues and good customs of the Chinese nation.

In fact, there is no need at all, we can't do anything for a penny at the moment.

In fact, this is not the case, this is just to not waste national resources.

This statement is not certain, and it can not be picked up, depending on your own situation.

It is said that this is more auspicious.

I picked up money, and when I was in elementary school, I picked up 20 yuan, and I was so excited that I finally bought spicy noodles and ate them.

When I was a child, I picked up five cents and handed it to the teacher, and the teacher praised me for being a good boy who picked up money. On the way home, I picked up 100 yuan and handed it to my mother, who made me a dumpling.

Then he threatened me to buy him snacks to eat, and then said that if I told my mother, once I told my mother that the money was gone, so I was threatened by him and bought him a lot of snacks, at that time it was still popular to eat snacks for one dollar and five dimes, unlike now. But he was so cheeky that he wanted to have a second time after having one, but I couldn't think of a better idea and didn't want to give it to my mother, so I couldn't buy it. In those days, we were really a local tyrant, all kinds of snacks, whether you like it or not, buy it, and give it to your classmates if you can't eat it.

Then the denomination of the money dropped sharply, just a few days later, I suddenly found that the money was gone, I knew that then I should save a little money, the money was gone, I could only watch others eat snacks, and I drooled when I saw it. I didn't think about handing it over to the police uncle or picking up gold, I didn't have that consciousness at the time, and now it seems that the way was wrong, but it doesn't change anything, I can only say that the only opportunity to find gold was wasted, and I haven't picked up money since.

Picked up a men's bag, tens of thousands of cash visually, bank cards, ID cards, driver's licenses, medical cards, etc., almost a person's card is proof, all in it, and there are large IOUs issued to him by others, decisively found the owner, and returned it to him.

It's something to be proud of, and it happened in my junior high school.

There is also a small episode at the beginning, which is at the flag-raising ceremony on Monday, a student was praised by the teacher in front of the majority of teachers and students because of the gold, mainly because the owner wrote a thank you letter for the school, which can be described as emotional and impassioned, so that the teachers felt gratified, so they would publicly praise the student on such an important occasion.

We don't know exactly how much money this student found, and the subsequent reports did not continue, and my focus was cut off. But after this incident, I am also looking forward to finding gold for once.

It was during a trip to the supermarket that my dream came true.

That time I went to the supermarket with my cousin and cousin, I was walking lazily, and I accidentally found that there was a piece on the ground that was not quite the same, after all, the floor of the supermarket was very clean, and it was obvious that it was different, I fixed my eyes and saw that it was 50 yuan, which should be a big windfall for us students at that time.

I walked over and picked up 50 yuan, and my cousin, a foodie, suggested buying food, but under my eyes, he stopped talking, so the 50 yuan was at my disposal.

I took 50 yuan to find the staff, the staff found the manager, the manager carefully asked us about the process of picking up the money, very angry is that the manager obviously does not trust us, at that time I wanted to break out, but helplessly we are few, it is inevitable that we will be outnumbered, I just endured.

After waiting for the manager to understand the situation, she comforted us a few words, and then said that we would contact us if there was something, and I fantasized about whether I would write a thank you letter, and then the reality deeply told me that things would not develop according to my own ideas.

The above is such a process, I am very proud, and there is no consequence.
