Zhu Ping'an glanced at everyone's reactions and raised the corners of his lips slightly, "Actually, my method is very simple, almost the same as cracking eggs just now."
After the revelation of the cooked eggs just now, these accountants no longer dare to underestimate Zhu Ping'an, but they also don't believe that there is such an easy way to detect false accounts in the world.
Looking at the various accountants who were whispering and discussing, Zhu Ping'an raised the corners of his lips slightly, "I know you don't believe it, and I wouldn't believe it either. However, there is no such absolute thing in the world.
This method was also accidentally learned from a senior expert whose real name was Ford when I was taking the college examination in Yingtian."
Speaking of this, Zhu Ping'an paused and said with a bit of embarrassment, "Actually, I have spent a lot of money, so I can make this method public to all the seniors, but all the seniors are in the accounting field.
Chu, my net worth is not comparable to that of a poor boy from a mountain village like me. I think your seniors will definitely not let me go home empty-handed. Although it is vulgar to talk about money, how can I avoid accounting, accounting, and checking accounts."
"Of course, it must be after the method has been verified." Zhu Pingan added lightly.
In fact, I didn't have this idea at first, but who made me feel a little unhappy with the attitude of these accountants towards me just now.
Besides, why not use intellectual property rights in exchange for some returns? My brother is getting married, and I have to take exams in the future. Why not do it if I can help my parents reduce the burden? Besides, I will use Benford's Law, which should have only appeared in the 20th century.
It was first proposed by the Ming Dynasty more than 400 years ago, and it can be regarded as a contribution to our country's mathematics. I don't know whether Benford's law will be called Ping'an's law in the future. Hahaha, what if it was discovered by Wai Guoren in the 20th century?
When China proposed this law more than 400 years ago, it would be very interesting to see what the reaction would be.
"If your method is really feasible, then it doesn't matter." The gray-haired accountant said leisurely, stroking his beard, with doubts still in his eyes.
"That's right, we are not cheap people."
"You tell me first, I don't believe there is such an easy way."
The other counting houses had different reactions, but they were all full of suspicion.
Zhu Pingan smiled and shook his head, and then said calmly, "This method is very simple. In fact, you only need to take the account book in your hand. Just look at the numbers that appear in the account book. From a bunch of data drawn from real life
, the number of occurrences of numbers with 1 as the first digit is about 30% of the total number of all numbers. The later the numbers appear at the beginning, the fewer the occurrences. Six, seven, eight, and nine together appear less than 20% of the time.
, as long as the discrepancy is too large, it must be a false account."
After all the accountants heard Zhu Pingan's method, they burst into laughter. How could it be possible? What a joke. They were treating the account books as child's play.
All the accountants who originally had high expectations were disappointed.
"Shouldn't the beginning of the number be the same? Whoever stipulated that 1 must appear 30% of the time. What a mess."
The accountants complained in different ways.
However, this situation was completely within Zhu Pingan's expectation.
"That's right. I had the same reaction at first. It completely goes against people's intuition: which number should start with the same number of times? But think about it carefully. Starting from 1, going through 1, 2, 39. Until this point
When it comes to ending, the number of numbers starting with them is the same, but after 9 there are 10 to 19. The number of numbers starting with 1 here is much higher than other numbers. And in the next pile of numbers starting with 9
Before a number appears, it must go through a bunch of numbers starting with 2, 3, 4, and 8. If this numbering method has an end point, the number of numbers starting with 1 will generally appear more often than 9."
"So, in the ledger data, the number of occurrences of numbers with 1 as the first digit is about 30% of the total number, and the number of subsequent numbers is smaller. Accounts that violate this rule must be fake accounts."
"If you don't believe it, you can find some other accounts and you will know the authenticity after a try."
Zhu Pingan's face was confident and his voice was sonorous and powerful. At this moment, he seemed to be a military advisor in the military formation, wearing a feather fan and silk scarf, and the powerful enemy was wiped out in ashes while talking and laughing.
The accountants talked a lot, but still didn't believe it.
"Dad, you can just use our family's account books and try it out. There will be no loss. If he makes it up randomly, watch how I scold him!"
The sinister girl walked up to Rich Man Li and pouted, then took Rich Man Li's arm with her slender hand and shook it.
Rich Man Li was only shaken twice, and then he waved his hand and asked Accountant Wang to fetch some account books.
Wang went to the accounting office for a while and came back with a stack of account books, about five or six of them.
As soon as the sinister lady Li Shu entered the Wang Accounting Room, she went up and grabbed it. Then she walked up to Zhu Pingan in two steps, glared at Zhu Pingan hard, and immediately pressed her into Zhu Pingan's arms.
"If you mess around, I want you to look good!"
Miss Li glared hard at Zhu Pingan, snorted, twisted her waist, and left Zhu Pingan with a proud back.
You are so arrogant, let’s see how you can get married!
Zhu Pingan slandered.
After receiving the account books, Zhu Ping'an distributed the six account books equally to the three accounting desks and said with a naive smile:
"The matter has come to this, seniors, you might as well give it a try. If there are any mistakes, Ping An is willing to admit defeat."
Just try it.
When the results come out, let’s see what excuses the kid will come up with!
The accountant followed suit, flipped through the account books, and calculated them. They calculated the account books that Zhu Pingan handed them once according to Zhu Pingan's method, and then took two of the account books to be checked and started calculating them.
In less than half an hour, these accountants completed the accounting.
Then, everyone was in a mess, looking in disbelief. Their faces were red, and the hands holding the account books were trembling. I don't know if they were excited because they got a method to check the accounts, or because they had misunderstood Zhu Ping'an just now.
Ashamed
"Oh my god, what I just got is about 30%, and these accounts are only about 10%."
“It’s really like that”
“It’s so weird”
"I still have a few account books here, I'll try again."
After a while, the cloth bag that Zhu Pingan was carrying was bulging with money. There were a lot of broken silver coins of two, two, and three taels, as well as many ten-tael silver notes, and even a fifty-tael silver note.
It was the gray-haired old accountant who forced it on Zhu Pingan with trembling hands. Zhu Pingan still couldn't shirk it. As soon as he pushed it, the old accountant blew his beard and stared. Are you saying that I have no eyesight and no knowledge of goods?
Helpless, Zhu Ping'an just had to accept the order. Speaking of which, these people are really honest.
This all works!
Hua'er, the steamed bun maid next to her, looked at the accountants who had originally laughed at Zhu Pingan, and each one rushed to stuff money and banknotes into Zhu Pingan's hands, with her little mouth opened in an O shape.
Sure enough, he was sold, and he helped the bad guy count the money!
The dark girl's eyes lit up, but when she saw Zhu Ping'an holding his schoolbag and smiling innocently, those beautiful eyes couldn't help but roll their eyes.
