Chapter 152: Fun Math Problems
In the evening of the same day, the CCTV news network also reported on the fact that Li Fan's works were compiled into Chinese textbooks. Pen | fun | pavilion www. biquge。 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.
"Awesome! In a short period of time, it has been on the news twice in a row!"
"Although they are all called Li Fan, they are not the same person. However, why is Li Fan so fierce?"
"Now it's time for Li Fan to return to the sixth-tier star, right?"
"That's for sure, those newspapers last time were really hateful. ”
“......”
Li Fan also watched the news broadcast, but he didn't have much feeling. These works were included in Chinese textbooks in their previous lives, 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 tournament is not something to celebrate. But the inclusion of four works in Chinese textbooks should be celebrated.
As a result, fans lined up on Li Fan's Weibo to leave messages, asking Li Fan to give something to celebrate this incident.
The fans are so enthusiastic, and Li Fan is not easy to refuse. But what can you say? Give everyone a red envelope? This is impossible, and this is not what the fans want.
What fans want is Li Fan to interact with them and have a good time. How do you want to interact? Li Fan touched his chin and thought quickly in his head.
Suddenly, he thought of the currently very popular "Young Di Renjie", and his eyes lit up. Since people in this world are so fond of detectives and solving crimes. It just so happens that I have a lot of interesting questions from my past life here, and I just happened 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'll give you the question, and you will answer it. There will also be a reward for the first person to answer correctly. ”
Li Fan's Weibo has just been issued, and there are dozens of comments below, and they are still increasing.
"Haha! It's funny, that's it. ”
"Okay, this is good, this is interesting. ”
"The key is what kind of topic you come up with, and you have to have interesting topics. ”
"Yes, yes. If there are a few math problems such as high math integrals, it will be boring. ”
“......”
This group of guys is quite demanding. Li Fan laughed in his heart, you guys will answer incorrectly later, don't doubt that your IQ is not enough. He thought about it for a moment and gave the first question.
"The enthusiasm is very high. So let's get started, let's warm up with a simple question. There is a well 7 meters deep, and a snail climbs up from the bottom of the well, climbs 3 meters during the day, and falls 2 meters at night. Q, how many days does a snail crawl out of a well?"
As soon as the question came out, there was a reply below.
"Haha! It's so easy. My son can answer it and the answer is 7 days. What kind of topic is this, can you do a good job?"
"Wow, the upstairs hand speed is so fast. The answer is 7 days, which is a kindergarten question. ”
"Yes, if you climb one meter a day, it must be 7 days. Li Fan isn't this guy kidding us. This guy is really hateful. ”
“......”
No surprise to Li Fan, the following answers are all 7 days. He smiled secretly in his heart and updated another Weibo.
"Everyone's answer speed is very fast. But alas, no one got it right. Alas, that's a kindergarten topic. What should you tell me to say? Forget it, I'm going to ask the 5-year-old guy next door to see if he can get it right. ”
"Ah! Li Fan is hateful. How could 7 days be wrong. ”
"That's it, I think this guy is deliberately angry with us. ”
"Okay, don't be embarrassed anymore. The answer doesn't seem to be 7 days. ”
"Not seven days? How many days is that?"
"If you draw this question on paper, you will know that it will be a few days. Alas, I got it wrong. Shame on you!"
"Draw it? Will the answer be different? Then I'll try, wow! The answer is 5 days. ”
"Five days? No, I'll try it. ”
At this time, fans discovered the tragedy. This is such a simple question, they really answered it wrong.
"Ahhh This question is trapped!"
"Haha! But I think this kind of question is so interesting! How did Li Fan come up with this question?"
"It's interesting. Hehe, I'm going to have to take this question to test others and make them doubt their own IQ. ”
Li Fan continued to ask questions, and now that I have found the trick to answer this kind of question, I will definitely not make any more mistakes. ”
“......”
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 has fallen into the trap of their own first judgment.
The correct answer came out, and Li Fan also came up with the second question, and he was also very interested now. Not only did I exchange feelings with the fans, but I could also "educate" the fans by the way, what a good thing.
"The question just now is just a warm-up. Now that we've figured it out, let's look at this question again. Master Wang sells shoes, a pair of shoes is sold for 30 and sold for 20, and the customer came to buy shoes and gave a 50 yuan. Master Wang had no change, so he asked a neighbor for 50, and later the neighbor found out that 50 was fake, and Master Wang accompanied the neighbor for 50. Q, how much did Master Wang lose in total?"
This question is very interesting and there will be multiple answers. Moreover, people with different answers think that their answers are correct and quarrel over rebuttals to each other's answers.
Li Fan can already foresee that his Weibo will not be calm in the short term. It's no surprise that fans will argue about the correct answer.
Li Fan laughed twice, ready to watch the excitement.
"It's a simple question. Master Wang's shoes are 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 not right upstairs. Master Wang enters 30 and sells 20, and here he loses 10 yuan. Plus 30 yuan for the customer and 50 yuan for the neighbor. It should be a loss of 10 + 30 + 50 = 90 yuan. ”
"No, no, none of your answers are right. Master Wang used 30 yuan to enter the shoes, and found 30 yuan for the customer, plus the 20 yuan he should have received. It should have lost a total of 80 yuan. ”
"You're all wrong. The money that Master Wang lost was actually the money he spent. The cost is 30 yuan plus 30 yuan for the customer. A total loss of 60 yuan. ”
"How do I feel like I've lost 70 yuan?"
"I feel like I've lost 40 yuan. Oh, what kind of question, how can there be so many answers. ”
"You don't have to argue, my answer of 90 yuan is absolutely correct. ”
"Go, 60 yuan is the right one. ”
"It's 110 yuan. ”
“......”
The facts did not disappoint Li Fan, and fans quarreled on Weibo about what they thought was the right 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 a neighbor. In fact, Master Wang used 50 yuan of fake money to exchange 50 yuan for real money for his neighbor, and finally exchanged 50 yuan for 50 yuan of fake money. Master Wang is actually not in or out of the neighborhood. The money lost is the cost of the shoes plus the money found by the customer.
Or it can also be understood in this way, the money that the customer gets is the money that Master Wang loses. The customer's money is 30 yuan for shoes, plus 30 yuan for Master Wang, a total of 60 yuan.
So, the answer of $60 is correct.
Li Fan saw that everyone was arguing, so he announced the correct answer on Weibo and analyzed the reasons.
"Haha! How's that?60 is correct. You people are still fighting here for a long time, really. ”
"It's 60 yuan, indeed. It's easy to think about it now. Why did I think it was 90 yuan at first?"
"Alas, the point is that this borrowing money here has misled us. ”
"These questions are so interesting. Does Li Fan still have such a question? ”
"That's it, go on. I've really got the hang of it. ”
