Little Farmer Big Star

Chapter 152 Interesting Math Problems

? That night, Huaguo CCTV News Network also reported on Li Fan's work being edited into Chinese textbooks.

Although there is only one sentence from the host, it is enough to make the majority of netizens, especially fans of Li Fan, excited for a long time.

"It's awesome! It's been on the news network twice in a short period of time!"

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

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

"That's for sure. The newspapers last time were really abominable."

""

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

However, his fans don't think so, and winning the top two in the competition is not cause for celebration. But such a big event that 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 say something to celebrate this event.

Fans are so enthusiastic, Li Fan is not easy to refuse. But what can be expressed? Red envelopes for everyone? This is impossible, and this is not what the fans want.

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 mind.

Suddenly, he thought of the very popular young Di Renjie, and his eyes lit up. Since people in this world like detectives and solving cases so much. It just so happens that I have a lot of interesting questions in my past life, and I just want to test these guys.

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

Li Fan's Weibo has just been released, and there are dozens of messages below, and it is still increasing.

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

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

"The key is what kind of questions are asked, and interesting questions are needed."

"Yes, yes. It would be boring if you did a few math problems such as high-number integration.

"

""

These guys are asking a lot. Li Fan's heart is funny, you guys will answer wrong later, but don't doubt that your IQ is not enough. He thought about it and gave the first question.

"Everyone's enthusiasm is very high. 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 came out, there was 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 solve it well!"

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

"Yeah, climb one meter a day, it must be 7 days. Li Fan is not kidding us. This guy is really hateful."

""

Not Li Fan's surprise, the answer below is 7 days. He smiled secretly in his heart and updated a Weibo again.

"Everyone answered the questions very fast. But it's a pity! No one answered correctly. Alas, this is a kindergarten question. What do you want me to say. Forget it, I'll ask the 5-year-old next door to me. Little guy, let's see if he can answer correctly."

"Ah! Li Fan is abominable. How could seven days be wrong?"

"That's right, I think this guy is trying to anger us on purpose."

"Okay, everyone, don't be embarrassed. The answer doesn't seem to be 7 days."

"Not seven days? Impossible. How many days was that?"

"You draw this question on paper, and you'll know it's been a few days. Oh, you got it wrong. Shame!"

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

"5 days? No, I'll try it."

At this time, fans made a tragic discovery. Such a simple question, they really got it wrong.

"Ahhh! It's really wrong. This question is stuck!"

"Haha! Although the answer is wrong. But I think this question is very interesting! How did Li Fan come up with this question?"

"It's really interesting. Hey, I have to take this question to test others, so that they doubt their own IQ."

"Li Fan continues to ask questions. Now that I have found the trick to answering this kind of question, I will definitely not make mistakes again."

""

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

The correct answer came out, and Li Fan also came up with the second question. He is also very interested now. Not only exchanged feelings with fans, but also "educate" fans by the way, what a good 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 is a shoe seller. A pair of shoes is sold for 30 yuan and sold for 20 yuan. Customers come to buy shoes and give a pair of 50 yuan. Wang The master had no change, so he asked the neighbor to exchange 50. Later, the neighbor found out that the 50 was fake, and Master Wang accompanied the neighbor for 50. Ask, how much did Master Wang lose in total?"

This question is very interesting, and there are many answers. Moreover, those with different answers believed that their answer was correct, and were arguing red-faced to refute the other's answer.

Li Fan can already foresee that his Weibo will not be calm in a short time. It's inevitable that fans will argue over the correct answer.

Li Fan laughed twice, ready to watch the fun.

"This question is also simple. Master Wang's shoes cost 30 yuan, plus 30 yuan for the customer, and finally 50 yuan with the neighbors. All the masters Wang lost a total of yuan."

"Hey, it's wrong upstairs. Master Wang sells 20 for 30, and here is a loss of 10 yuan. Plus 30 yuan for the customer and 50 yuan for the neighbor. It should be a loss of yuan."

"No, no, both of your answers are wrong. Master Wang spent 30 yuan for the shoes, 30 yuan for the customer, plus the 20 yuan he should have earned. A total of 80 yuan should be lost."

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

"Why do I feel like I should have lost 70 yuan?"

"I feel like I lost 40 yuan. Oh, what is this question, how come there are so many answers."

"You don't have to argue, my answer is absolutely correct for 90 yuan."

"Go, 60 yuan is correct."

"It's obviously 110 yuan."

""

The fact did not disappoint Li Fan, and fans quarreled on Weibo about what they thought was the right answer or wrong answer. Li Fan was also happy to watch the excitement.

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

Or it can be understood in this way that the money the customer gets is the money that Master Wang loses. The money the customer gets is 30 yuan for shoes, plus 30 yuan from Master Wang, the total is 60 yuan.

So, the answer of 60 yuan is correct.

Seeing that everyone was arguing almost, Li Fan announced the correct answer on Weibo and analyzed the reasons.

"Haha! How's it going? 60 is right. You guys 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 at first?"

"Well, the key is that this borrowing money here misleads us."

"These questions are too interesting. Does Li Fan still have such questions? Go ahead."

"Yeah, go on. I've really got the hang of it now."
