Chapter 579 Surprised by Jinbao's question

Liu Changping was worried that Jinbao would ask some strange questions, such as how many stars are in the sky that no one could answer, so he hurriedly said: "Wait a minute! Children, since you want to test Shuting's cultural knowledge, the question must be

There are standard answers”

Jinbao nodded his head twice, "Of course, what I asked was a calculation question."

Unexpectedly, this girl asked a calculation problem. Xie Shuting couldn't help but chuckle in her heart. A first-year elementary school student actually came up with a calculation problem that stumped her.

Holding back her sarcastic sneer, she said, "Since it's a calculation question, I have to memorize it, right?"

"Okay, just remember it."

Jinbao looked at her third brother and asked, "Third brother, do you have a pen and paper?"

"Bring it." Su Wennian took out a pen and a notepad from his backpack.

Because the notebook contained the contents of today's production team meeting, he did not hand the entire notebook to Xie Shuting, but tore off one of the blank pages and gave it to her.

In order to write better, Xie Shuting asked Liu Changping to bend down and use his back as a table.

When everything was ready, she said in a relaxed tone: "You start asking questions."

Jinbao said slowly: "Liu Mei is an educated youth who joined the production team in Luohu Village. Her parents gave her thirty yuan before the trip. Her monthly living expenses are five yuan. She earns every day in the production team.

The work points are six points, while the work points of male educated youths during the same period are ten points, and they can get 40 cents a day..."

Everyone listened curiously.

Xie Shuting thought to herself: She must be asking Liu Mei how much money she can save in a year. It is so simple.

A male educated youth earns 40 cents per day for ten work points, while a female educated youth earns 6 cents, which is four divided by ten, and then multiplied by six, which is 24 cents per month, which is...

Xie Shuting did some mental calculations. She earned 7.2 yuan a month, deducted 5 yuan for expenses, and the remaining two yuan was 26.40 cents a year. Plus the 30 yuan given by her parents, after one year

The total amount is fifty-six yuan and four cents. It’s really a question asked by an elementary school student.

Just when she was triumphant and ready to tell the answer, she didn't expect that the question Jin Bao said later was completely different from what she thought.

Just listen to Jinbao continue: "Liu Mei rides a bicycle to the rural credit cooperative in the town to save money every month. It is known that the five-year regular interest rate of the credit union is 8.28%. She deposited the thirty yuan given by her parents.

For five years, and then after five years of zero deposit withdrawal, I deposited all the remaining money every month. How much money will Liu Mei be able to withdraw from the credit union in total after five years?"

"What's the roundup?" Xie Shuting was a little confused.

Jinbao explained: "Single deposit withdrawal is a way of depositing money. You save a fixed amount every month and then withdraw the money at once."

After Xie Shuting finished memorizing all the questions, Liu Changping took it in his hand and took a look at it. He thought that it is easy to save thirty yuan for five years, which is 30*(1+5*8.28%)=42.42. But how to calculate the sum of the fractional deposits and withdrawals?

?

"You high school graduates must be very good. You should be able to solve such a simple math problem in half an hour, right? If you can't solve it, you lose."

As soon as Jinbao finished speaking, Liu Changping asked anxiously: "You didn't tell me how much the interest rate is on the small deposits and withdrawals? There is one missing condition."

"Ah? Of course you have to calculate this. If I tell you, this question will be too simple."

"This..." Liu Changping frowned.

Jin Bao's voice was soft and waxy, "Big brother, although you are a friend of Sister Xie Shuting, you can't help her calculate the answer. She has to calculate it by herself. If I lose, she will take all my family's answers."

All the chickens have been taken away.”

Liu Changping looked embarrassed, "The question you asked is too..."

"Is there any problem with my question? It must have a standard answer, right?"

"Although there is a standard answer, it is too tricky and difficult. If you save it for five years, you will be sick..."

Before Liu Changping could continue, Su Wenian smiled and said: "My sister's question is not difficult at all. I can calculate the answer in five minutes."

The other educated youth present looked at each other in confusion, thinking that this question could be solved in 5 minutes? How is that possible? Isn't he bragging too much?

Someone suspected: "You told your sister this question before. Of course you can calculate it. You already know the standard answer."

Before Su Wenian could speak, Jinbao said: "This question was just a random thought of mine, not something my third brother told me."

"What do you think? You are so young, how can you come up with such a topic?"

"What's so difficult about this? My father often goes to rural credit cooperatives to either withdraw money or deposit money. It's normal for me to think of this question, right?"

After the little girl finished speaking, Luo Zhongqiang raised his hand and said: "I testify that Comrade Su Jianmin really likes to go to credit unions. Unlike me, I like to keep money in my pocket. I feel that it is not safe to put it in the bank."

After everyone listened to what he said, they thought that Su Jianmin often took his daughter to the bank. No wonder Jinbao could figure out the problem of saving money.

They are all very curious. If they put this money in a credit union and save it for 5 years, how much money will they get?

Xie Shuting was staring at the question with a frown on her face. How should she calculate this question?

Saving two yuan a month for five years means sixty months...

Then doesn’t she have to count it 60 times?

Jin Bao smiled and said: "If you can't figure it out, just give up. If you give up now, you just need to apologize to my fourth brother and forget about doing odd jobs."

Things have reached this stage, with so many people around staring at her, how could she admit defeat now? Xie Shuting felt that she could not afford to lose face.

She hummed, "Just wait, I will definitely calculate it within half an hour! Isn't it just 60 times? My arithmetic ability is very strong!"

At this point, she asked: "Can I borrow a table? There is no place to write, how can I do calculations?"

"Okay, you can come to my house to count. Once you sit down, I will start timing."

Seeing Xie Shuting walking into Su's house, everyone watching the excitement wanted to know the result and couldn't help but follow her in.

There was a circle of people crowded around the Su family's dining table. They were laughing and talking.

"This educated youth is quite powerful. I can't even understand the topics Jinbao said, haha..."

"Look what these things she wrote are about? This bunch looks like ghost drawings."

Luo Zhongqiang and the villagers explained: "These are numbers. They are not symbols. The cross is a multiplication sign, and the one next to it is a parenthesis..."

"Aqiang, you are even more powerful. After going to the town for three years to study in elementary school, the ties are different! But what are the two circles and the line in the middle?"

Luo Zhongqiang stared at "%" for a while, "I have never seen this symbol before."

Xie Shuting thought to herself: They have never even seen a percent sign, they are really a bunch of illiterate people.

Today she has to solve this problem! Let them see that after studying for so many years, she did not graduate from high school in vain!
