Chapter 152： Fun math problems

In the evening, the Hua Guo CCTV News Network also reported on Li Fan's work being compiled into Chinese textbooks.

Although there is only one sentence from the host, it is enough to excite the majority of netizens, especially Li Fan's fans.

"Awesome! Two consecutive news broadcasts in a short period of time!"

"Although they are called Li Fan, they are not the same person. But why are they called Li Fan so fierce?"

"It's time for Li Fan to return to the sixth-tier star, right?"

"That's for sure, the last few newspapers were really hateful."

"..."

Li Fan also watched the news broadcast, but he didn't feel much. These works have been compiled into Chinese textbooks in previous lives, and it is normal for them to be compiled in this world.

However, his fans don't think so. Winning the top two in the competition is not worth celebrating. But the event that the four works were compiled into Chinese textbooks should always be celebrated.

As a result, fans lined up to leave messages on Li Fan's Weibo, asking Li Fan to give something to celebrate the event.

Fans are so enthusiastic that Li Fan is not easy to refuse. But what can it show? Red envelopes for everyone? This is impossible, and the fans don’t want this.

Fans want Li Fan to interact with them and have a good time. How to interact? Li Fan touched his chin, thinking quickly in his head.

Suddenly, he thought of the very popular "Young Di Renjie", and his eyes lit up. Since people in this world like detectives and solve crimes so much. It just so happens that I have a lot of interesting questions in my previous life, so I just have to take a test of these guys.

After making up his mind, Li Fan wrote on Weibo: "Since everyone is so enthusiastic, let's play a game. I have a question and you will answer. The first person to answer the correct answer will have Reward."

Li Fan's Weibo has just been posted, and there are dozens of comments below, and they are still increasing.

"Haha! This is interesting, just do it."

"Okay, this is good, this is interesting."

"The key is what kind of question is asked, and it must be interesting."

"Yes, yes. It would be boring if you do a few math problems like high integrals."

"..."

This group of guys have a lot of demands. Li Fan was funny, you guys got the wrong answer later, don't doubt your IQ is not enough. He thought for a while and gave the first question.

"Everyone's enthusiasm is very high. Then let's start with a simple question to warm up. There is a well 7 meters deep, and a snail climbs up from the bottom of the well. It climbs 3 meters during the day and falls 2 meters at night. . Ask, how many days can the snail crawl out of the well?"

As soon as the question comes out, there will be a reply immediately below.

"Haha! This is too simple. My son can answer it, and the answer is 7 days. What kind of question is this? Can you make a good question!"

"Wow, the hands are so fast upstairs. The answer is 7 days. This is a kindergarten problem."

"Yeah, climbing one meter a day, that must be 7 days. Li Fan is not kidding us, right? This guy is really hateful."

"..."

Not surprisingly to Li Fan, the answers below are all 7 days. He secretly smiled and updated another Weibo.

"Everyone's answering questions are very fast. But it's a pity! No one answered correctly. Alas, this is a kindergarten question. What can you tell me. Forget it, I'll go and ask the 5-year-old next to me. Little guy, see if he can get it right."

"Ah! Li Fan is an abomination. How could it be wrong in 7 days."

"Yes, I think this guy came to **** us off on purpose."

"Okay, don't be embarrassed anymore. The answer does not seem to be 7 days."

"Not 7 days? Impossible. How many days are they?"

"You drew this question on paper, and you know it's been a few days. Alas, I got it wrong. It's shameful!"

"Draw it out? The answer will be different? Then I try, wow! The answer turned out to be 5 days."

"Five days? No, I will try."

At this time, fans found a tragedy. This is such a simple question, they really got it wrong.

"Ahhhhh! It was really wrong. This question is stuck!"

"Haha! Although I got it wrong. But I think this question is really interesting! How did Li Fan come up with this question?"

"It's really interesting. Hey, I have to take this question to test others, to make them doubt their IQ."

"Li Fan continues to write questions. I have now found the knack for answering this kind of questions. I will definitely not make mistakes again.

"..."

This question is actually very simple, as long as you draw on the notebook, the answer will come out. It's just that everyone has fallen into the trap of their own first judgment.

The correct answer came out, and Li Fan followed up with the second question. He is also very interested now. Not only can I exchange feelings with the fans, but I can also "educate" the fans by the way. What a great thing.

"The question just now is just a warm-up. Now that everyone has found the trick, let's look at this question again. Master Wang sells shoes. A pair of shoes is sold at a price of 30 and sold at 20. The customer came to buy shoes and gave a piece of 50 yuan. Wang The master had no change, so he exchanged 50 for his neighbor. After the neighbor discovered that 50 was a fake, Master Wang accompanied his neighbor 50. Ask, how much did Master Wang lose?"

This question is very interesting, there will be multiple answers. Moreover, people who hold different answers think that their answers are correct, and quarrel with each other's answers.

Li Fan can already predict that his Weibo will not be calm in a short time. It is inevitable for fans to argue about the correct answer.

Li Fan chuckled twice, ready to watch the excitement.

"This question is also simple. Master Wang's shoes cost 30 yuan, plus 30 yuan for the customer, and finally 50 yuan to accompany the neighbor. All Master Wang lost a total of 30AA30AA50=110 yuan."

"Hey, the upstairs is not right. Master Wang sold 20 for 30, and here is a loss of 10 yuan. Add 30 yuan to the customer and 50 yuan to the neighbor. It should be a loss of 10AA30AA50=90 yuan."

"No, no, neither of your answers are right. Master Wang used 30 yuan for the shoes, and gave the customer 30 yuan, plus the 20 yuan he should have received. A total of 80 yuan should have been lost."

"You are all wrong. The money that Master Wang lost is actually the money he spent. The cost is 30 yuan plus the 30 yuan that he gave to the customer. The total loss is 60 yuan."

"How do I feel that I should have lost 70 yuan?"

"I feel that I have lost 40 yuan. Oh, what kind of question is this? How can there be so many answers."

"Don't argue, my answer is 90 yuan is absolutely correct."

"Go, 60 yuan is correct."

"It's clearly 110 yuan."

"..."

The facts did not disappoint Li Fan. Fans were arguing about what they thought were correct and wrong on Weibo. Li Fan was also happy to watch the excitement.

This question is actually simple. Everyone was mainly misled by Master Wang borrowing 50 yuan from neighbors. In fact, Master Wang used 50 yuan of fake money in exchange for 50 yuan of real money for his neighbors, and finally used 50 yuan of real money in exchange for 50 yuan of fake money. Master Wang is actually not in and out of the neighbors. The money lost is the cost of shoes plus the money given to customers.

Or it can be understood that the money that the customer gets is the money that Master Wang loses. The customer's money is 30 yuan for the shoes, plus the 30 yuan that Master Wang asked him, for a total of 60 yuan.

Therefore, the answer of 60 yuan is correct.

Seeing that everyone's quarrel was almost over, Li Fan announced the correct answer on Weibo and analyzed the reason.

"Haha! How is it? 60 is correct. You people are still fighting here for a long time, really."

"It's really 60 yuan. It's easy to think about now. Why did I think it was 90 yuan in the first place?"

"Oh, the key is that borrowing money here misled us."

"These questions are so interesting. Does Li Fan have any questions like this? Keep going."

"Yes, go ahead. I really found the trick right now."
