Chapter 776: Wisdom test? Force me to copy the question

Chapter Seven Hundred and Seventy Six
Seeing that Chu Jing was about to fall into the ground and become muddy.
In the next second, a vine flew out of nowhere, wrapped Chu Jing's waist, and entangled him tightly.
In an instant, Chu Jing's downward momentum was stopped, and he was set in mid-air less than 30 meters from the ground.
"Not dead? It really came?"
Chu Jing let out a long sigh of relief, his body was soaked in cold sweat.
The vines suddenly rose, just like the elevator just now, carrying Chu's surprise to the upper and top floors.
Chu Jing's heart was filled with the joy of the rest of his life.
Looks like I guessed it right?
...
"Brother Yan, am I dazzled just now?"
Outside the royal ancient tree, Dugu Jiujian said to Yan Guiyun.
Yan Guiyun looked up at the ancient royal tree towering into the clouds.
Just now, he and his little brother visited Wangcheng as usual, looking for some potential shop locations.
But suddenly I heard a scream.
Then they looked up and saw a figure falling down.
Because they were so far apart and because it was night, they couldn't see what the man was like.
But they are definitely not dazzled.
Someone really jumped off the building at the Royal Old Tree!
But inexplicably, they are all ready to watch the scene of the meat exploding.
As a result, the figure suddenly disappeared?
"Dizzy? How can it be dazzled when two people see it together?"
Yan Guiyun said angrily.
"What the is going on? Why would someone jump off the building in the palace? And suddenly disappeared?"
Dugu Jiujian said in a puzzled manner.
Yan Guiyun shrugged and said, "How do I know, maybe it's the plot of an Easter egg designed by this game designer?"
The two left with doubts.
They don't think that the person who just jumped off the building is a player.
Because of the current stage.
Don't say they are stars.
Even if the God of Wealth will come, there is no ability and qualification to enter the ancient royal tree.
Judging from the height where the guy fell just now.
He apparently jumped from the top floor.
Where is that?
The palace!
The location of the Elf King!
No player can enter the ancient royal tree, let alone enter the palace on the top!
At this stage, absolutely impossible!
So the person who jumped off the building is definitely not a player.
Well, it must be a boring plot designed by game planning.
This is the idea of ​​the two.
...
Chu Jing returned to the palace.
In front of him, there was no expression on the Elf King's face.
No, he still seemed very cold and murderous.
But Chu Jing was not afraid.
Because a line of system prompts appeared before his eyes.
"The Favorability of the Elf King +1..."
This discovery made Chu surprised and overjoyed.
Obviously, his act of jumping off the building daringly just now aroused the deep praise of the king.
Don't look at how disdainful and cold this guy is on the surface, but in his heart he has already recognized that he is surprised, right?
"Young man, you are brave, but in many cases, this so-called bravery is nothing more than recklessness."
The elf king said angrily: "You know if you really died like this. Will the face loss to our elf royal family be very serious?"
It must be.
Someone jumped off the building at the royal old tree. This is definitely big news.
But for the royal family who pays attention to class etiquette.
This is equivalent to Chi Guoguo's face.
Chu Jing apologized seriously: "I'm sorry, my lord, I just want to prove my courage, and my behavior is a bit reckless. I will correct it next time."
The anger in the eyes of the elf king dissipated a little, and he said slightly: "Human, I appreciate your humble attitude, but then again, courage is not enough to be my daughter's friend, you must have a certain amount of wisdom!"
Chu Jing Wenyan nodded and said, "In terms of wisdom, I have confidence in myself!"
He can figure out that foreign countries are testing themselves, first testing courage, and testing wisdom?
It seems easy to understand.
The Elf King sneered: "Have confidence? That's great, so let's go. I wrote a topic here. Take it and see. If you can answer the topic within two minutes, you can prove that you are unparalleled in wisdom and capable of becoming me. The qualifications of a daughter's friend."
Chu Jing didn't rush to get the note on the table, but asked: "Then if I am qualified to be a true friend of His Royal Highness Vivian, do you think about helping me, King?"
The elf king blew his beard and stared, "If you could really be my daughter's friend, would I not help you? In your eyes, I am such an incompetent person?"
Chu Jing immediately raised his hand and smiled apologetically: "I'm sorry, the king, I didn't mean that..."
"Huh! Hurry up and answer the questions, your time is running out!"
The elf king said impatiently.
Chu Jing nodded, took the small note, and scanned it carefully.
He didn't expect it to be an arithmetic problem...
Although Chu Jing was admitted to a good university, his grades passed.
But in fact……
His mathematics ability is very poor, and it is also the weakest link in his major subjects.
Is this problem still a math problem?
Isn't this killing me?
Topic: "A little monkey has 100 bananas next to it. It has to walk 50 meters to get home. Each time it moves up to 50 bananas, it will eat one every 1 meter. How many bananas can it hold? Move to home?"
Looking at the tall and reckless elf king, how could he set up such a delicate math problem?
Chu Jing was also full of question marks.
If there is enough time, Chu Jing calms down and recalls the little mathematics knowledge he has left, maybe he can slowly solve this problem.
But now, he is very anxious.
Because when he picked up the note, there was a countdown in front of him.
Now the display time is 90S.
This means that Chu Jing still has ninety seconds to solve the problem.
Time is still passing by.
Chu was so anxious that he couldn't concentrate on thinking at all.
"No? Really want to play with me?"
Chu Jing was full of distress, "I don't know how to solve the problem at all? Let's play with wool? If we can't solve it, our plan will fail?"
"Is there a way to solve the problem?"
Suddenly, Chu was anxious.
"Am I stupid? Although I'm playing games, I'm also surfing the Internet. It seems that the Elf King didn't say that I can't check the answer online, right?"
"And even if he said it, it's useless. He can only program, I am a human, how can I know if I secretly check him?"
Thinking of this, Chu Jing was already very pleasantly surprised. He immediately opened the web page and output the keywords for this topic.
He prayed in his heart that there must be an answer online.
Otherwise, I'm really finished...
The good news is that luck is rewarded.
Through the search engine, Chu Jing quickly found this question, and the answer is attached below!
Suppose the monkey walks from 0 to 50. When he reaches point A, he can directly hold the banana and go home, but when he reaches point A, he consumes at least 3A of bananas (to A, back to 0, to A). One restriction is the monkey You can only hold 50 bananas, so the monkey at point A can have up to 49 bananas. 100-3A=49, so A=17. So when the tossing is finished, the bananas are 100-3A-(50-A)=50-2A = 16.
