Chapter 169： it's all right

Chapter 169 This is okay

Zhu Pingan glanced at everyone's reactions, and raised the corners of his lips slightly, "Actually, my method is very simple, similar to cracking eggs just now."

After the boiled eggs came out just now, these accountants didn't dare to underestimate Zhu Pingan anymore, but they didn't really believe that there would be such an easy way to detect fake accounts in the world.

Seeing all the accountants whispering and discussing, Zhu Pingan raised the corners of his lips slightly, "I know you don't believe it, and I wouldn't believe it if it were me. However, there is no such absolute thing in the world. This method was also given to me by chance when I took the college exam in Yingtian from a senior expert whose real name is Ford."

Speaking of this, Zhu Pingan paused, and said with a little embarrassment, "Actually, I paid a lot of money, so I can disclose this method to all seniors, but all seniors are accounting workers. Chu, my wealth is not comparable to that of a poor boy in a mountain village like me, I think the seniors will definitely not let me go home empty-handed. Although talking about money is vulgar, how can I avoid accountants and account checks?"

"Of course, it must be after the method is verified." Zhu Pingan added another sentence lightly.

In fact, I didn't have this kind of thought at first, but who made me feel a little uncomfortable with the attitude of these accountants to me just now.

Besides, why not exchange intellectual property rights for some returns. My brother is getting married, and I have to rush for the exam in the future, so why not do it if I can help my parents reduce the burden. What's more, I first proposed Benford's law, which should have appeared in the 20th century, in Daming more than 400 years ago, which can be regarded as a contribution to Chinese mathematics. It is not clear whether this Benford's law will be called the law of peace in the future. Hehehe, if the crooked nuts in the 20th century discovered that this law was proposed in China more than 400 years ago. It will be very interesting what kind of reaction it will be.

"If your method is really feasible. So what's the matter." The grey-haired accountant smoothed his beard and said leisurely, with doubts in his eyes.

"That's right, we are not cheap people."

"Let's listen first, I don't believe there is such a simple method."

The rest of the accountants had mixed reactions, but they were all suspicious.

Zhu Pingan smiled and shook his head, then said lightly, "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. The number of times the number 1 appears as the first digit in the account book The proportion of the total number of all numbers in this ledger is about 30%, and the number of times 2, 3, 4, 5, and 9 appears as the first word accounts for a smaller and smaller proportion of the total number of numbers. The total number of numbers appearing as the first word accounts for less than 20%, if the ratio is too different from what I said, it must be a fake account."

After hearing Zhu Pingan's method, all the accountants burst into laughter. How could it be possible? What a joke. It is completely treating the ledger as a child's play.

The accountants who were expecting so much were disappointed.

"Shouldn't the number at the beginning be the same? Whoever stipulates that 1 must appear in 30% of the numbers. Mess up"

The accounting office complained differently.

However, this situation was completely within Zhu Pingan's expectation.

"That's right, when I got this method for the first time, I also had the same reaction as you. I also thought that all the numbers should appear almost the same number of times. But after Mr. Benford's explanation, I finally understood. Seniors, you can Think about it carefully, the 9 numbers from 1 to 9 appear once for everyone, which is the same. But after 9, 10, 11, 12, 13... whoever is not 1 appears more times, after 2 , 3, 4, 5, 6, 7, and 8 appear as the first character, and then it will be the turn of 9 to appear as the first character. If it continues, the number of occurrences of 9 as the first character must be the least, and the number with the first character 1 appears The number of times is generally more than the number of times 9 appears as the first word."

"So, in the ledger data, numbers with 1 as the first digit appear about 30% of the total number, and the number of occurrences is smaller as the number goes later. A ledger that violates this rule must be a fake ledger."

"If you don't believe it, you can find some other ledgers, and you can tell if it is true or not."

Zhu Ping'an's face is full of self-confidence, and his voice is sonorous and powerful. At this moment, he seems to be a military adviser in the army who is pointing the country.

According to the accountants, they still don't believe it.

"Daddy, just take our family's account book and try it out. There is no loss. If he makes it up, let me see how I scold him!"

The black-bellied girl walked up to rich man Li and pouted, holding rich man Li's arm with her slender hand and shaking it.

Big rich man Li was only shaken a couple of times before he waved his hand and asked the accountant Wang to fetch some ledgers.

Wang went to the accountant for a while, and then came back with a stack of ledgers, probably five or six.

The black-bellied lady Li Shu just entered Wang's accountant's room, she went up and snatched it, then walked up to Zhu Ping'an in two steps, gave Zhu Ping'an a hard look, and immediately pressed her into Zhu Ping'an's arms.

"If you mess around, I want you to look good!"

Miss Li gave Zhu Pingan a hard look, snorted, and twisted her waist to give Zhu Pingan a proud back.

You are so arrogant, let's see how you can get married!

Zhu Ping'an was defamed.

After receiving the ledger, Zhu Pingan divided the six ledgers equally among the three accountants, and said with a silly smile:

"The matter has come to this, seniors may wish to give it a try. If there is a mistake, Ping An is willing to gamble and admit defeat."

Try it and try it.

Wait for the results to come out, and see what excuses the kid is making!

The accountant went along with the flow, turned over the account books and started to calculate, calculated the account book that Zhu Ping'an handed them according to Zhu Ping'an's method, and took two of the account books to be checked and started to calculate.

In less than half an hour, these accountants calculated the accounts.

Then, all of them were messed up, and they all looked in disbelief, their faces were flushed, and the hands holding the ledger trembled a little. I don't know if it was because they were excited about getting a way to check the accounts, or because they had misunderstood Zhu Pingan just now. ashamed

"My God, the ones I just brought are about 30% of the bills, and these accounts are only about 10%"

"It's really like this"

"It's weird"

"I still have a few ledgers here, I'll try again."

After a while, Zhu Ping'an's cloth bag slung across his shoulders was bulging. There were a lot of broken silver in twos and threes, and there were also many ten-two silver notes, and even a fifty-two silver note. It was the gray-haired old accountant who forced it to Zhu Pingan with trembling hands, but Zhu Pingan couldn't evade it. As soon as he pushed it, the old accountant blew his beard and stared. Are you saying that I am blind?

Helpless, Zhu Pingan just accepts everything as ordered. In other words, these people are really real.

It works!

The bun maid Hua'er next to her looked at these accountants who had been laughing at Zhu Ping'an differently, one by one scrambling to put money into Zhu Ping'an's hand, her little mouth opened into an O shape.

Sure enough, it was sold, and it even helped the bad guy get money!

The black-bellied girl's eyes lit up, but when she saw Zhu Ping'an's innocent smile while touching her schoolbag, those beautiful eyes couldn't help but rolled her eyes.
