Little Farmer Big Star

Chapter 152 Interesting Math Problem

That night, Huaguo CCTV News Network also reported that Li Fan's works were compiled into Chinese textbooks. www. biquige. info

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

"It's amazing! 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, okay? But why are all the people named 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 hateful."

"..."

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

His fans, however, don't think so, and winning the top two in the big competition is not something to celebrate. But such a big event as four works being compiled into Chinese textbooks should be celebrated.

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

Fans are so enthusiastic, Li Fan can't refuse. But what can you say? Red envelopes for everyone? This is impossible, and this is not what the fans want.

What the fans want is for Li Fan to interact with them and have a good time. How to interact? Li Fan rubbed his chin, thinking quickly in his mind.

Suddenly, he thought of the very popular "Youth Di Renjie", and his eyes lit up. Since people in this world like detectives and solving crimes so much. It just so happens that I have a lot of interesting questions from past lives here, so I just want to test this group of guys.

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

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

"Haha! This is interesting, let's do it like this."

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

"The key is what kind of topic to come up with, and the topic must be interesting."

"Yes, yes. If you complete a few math problems such as advanced integrals,

That's so boring. "

"..."

These guys are asking a lot. Li Fan was amused, you guys will answer wrong 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. Let's start. Let's start with a simple warm-up question. 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 does it take for a snail to crawl out of a 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 make a good question!"

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

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

"..."

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

"Everyone's answering speed is very fast. But it's a pity! No one got it right. Hey, this is a kindergarten question. What can you tell me. Forget it, I'll ask the 5-year-old next door. Little guy, let's see if he can get the answer right."

"Ah! Li Fan is a horrible guy. How could it be wrong for 7 days."

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

"Okay, everyone, don't be ashamed anymore. The answer seems to be really not 7 days."

"Not 7 days? Impossible. How many days is that?"

"If you draw this question on paper, you'll know it's been a few days. Alas, you got the answer wrong. Shame!"

"Draw it? Will the answer be different? Let me try, wow! The answer is 5 days."

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

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

"Ahh! It's really wrong. I got stuck in this question!"

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

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

"Li Fan continued to ask questions. Now that I have found the trick to answer 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 first judgment.

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

"The question just now was 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 bought for 30 yuan and sold for 20 yuan. The customer came to buy shoes and gave a piece of 50 yuan. Wang The master had no change, so he asked a neighbor to exchange 50, and the neighbor found out that the 50 was fake, and Master Wang accompanied the neighbor for 50. Ask, how much money did Master Wang lose in total?"

This question is very interesting and there will be many answers. Moreover, people who hold different answers think that their answers are correct, and they are arguing to refute each other's answers.

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 chuckled twice, and was ready to watch the excitement.

"This question is also simple. Master Wang's shoes cost 30 yuan, plus 30 yuan for customers, and finally 50 yuan for neighbors. All Master Wang lost a total of 30+30+50=110 yuan."

"Hey, it's wrong upstairs. Master Wang sold 20 yuan for 30 yuan, and here is a loss of 10 yuan. Add the 30 yuan for the customer and the 50 yuan for the neighbor. It should be a loss of 10+30+50=90 yuan. "

"No, no, your answers are all wrong. Master Wang used 30 yuan to buy the shoes, and gave the customer 30 yuan, plus the 20 yuan he should have gotten. There should be a total loss of 80 yuan."

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

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

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

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

"Go, 60 yuan is the correct amount."

"It's obviously 110 yuan."

"..."

The facts did not disappoint Li Fan. Fans quarreled on Weibo over what they believed to be the correct answer. Li Fan was also happy to watch the excitement.

This question is actually simple. Everyone was mainly misled by Master Wang who borrowed 50 yuan from his neighbors. In fact, Master Wang exchanged 50 yuan of fake money for 50 yuan of real money to his neighbors, and finally exchanged 50 yuan of real money for 50 yuan of fake money. Master Wang actually can't come in and out of the neighbor's place. The money lost is the cost of the shoes plus the change to the customer.

Or it can be understood in this way that the money that the customer gets is the money that Master Wang loses. The customer got 30 yuan for the shoes, plus 30 yuan that Master Wang gave him, making a total of 60 yuan.

Therefore, the answer of 60 yuan is correct.

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

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

"It is indeed 60 yuan. Now that I think about it, it is very simple. Why did I think it was 90 yuan at first?"

"Well, the key is that this borrowing money has misled us."

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

"That's right, go ahead. Now I've really found the knack."

"..."

Thank you very much, Li Yao and Tianju Blood Soul, two friends for their rewards! Thanks! (To be continued.)
