universal data

Chapter 116 Who said that you only need to know addition, subtraction, multiplication, and division to buy groceries!
"And..." Cheng Nuo walked to the booth, shook the bundle of spinach in his hand, then pretended to observe it carefully, and continued to speak.

"When spinach is picked from the soil, in a short period of time, because the cells have not died, it will still perform photosynthesis and respiration. Photosynthesis 6 CO2+12 H2O===C6H12O6 + 6 O2+ 6 H2O, respiration C6H12O6 + 6 O2+ 6 H2O===6 CO2+12 H2O.”

"Boss, you said that the time you picked was last night. In the absence of light, photosynthesis will not be carried out at all, organic matter will be produced, and only respiration will be carried out to consume organic matter. It stands to reason that the organic matter content of spinach at this time should be higher than that of spinach. Less cases to grow!"

"But!" Cheng Nuo changed his tone, pushed up his glasses, and said with a faint smile, "I bumped it just now. According to my many years of experience in shopping for vegetables, the weight of this spinach is about 580 grams. And according to a man named Wo · According to the Zigbenzde formula, the organic matter content can be found to be about 56 grams, which is about 5 grams higher than the normal value."

"What does this mean? It means that after you pick the spinach, the leaves of the spinach still undergo photosynthesis for a period of time. In the dark night, photosynthesis is impossible. So, I dare to judge, boss you The time to pick spinach is not in the middle of the night, but... during the day!"

"The normal growth cycle of spinach is about 37 days, and the time since your spinach was planted to the present, I observed it just now, and it has been almost 41 days. Therefore, I boldly speculate that you, boss, planted it two or three days ago. One morning, I picked these spinach back in the greenhouse. Then put it outside in the sun for about an hour. Then put it in a dark place to keep fresh, and finally, bring it to the vegetable market to sell!"

"So, I really think there is only one! Boss, what you said is completely false! This is not freshly picked spinach at all!" Cheng Nuo's voice couldn't help raising his voice a little, which aroused the attention of the people around him.

"Boss, I don't know, am I right in my analysis?" Cheng Nuo looked at the female boss with a smile on his face.

When Cheng Nuo saw the bundles of spinach for the first time, he was already suspicious.

If it is freshly picked spinach, the green color on the leaves will definitely be gleaming green, so green that it will make you panic.

But the spinach spread by the female boss did not make Cheng Nuo feel that panicked at all.

So he activated his ability and simply glanced at it.

Sure enough, with Cheng Nuo's astute brain as a top student, he quickly used the data in his eyes to perfectly deduce the exact time for the female boss to pick spinach.

Silence... the silence of the night...

The female boss opened her mouth wide and looked at Cheng Nuo in astonishment, unable to utter a word.

Because... everything Cheng Nuo said was right!
This batch of spinach was indeed picked by her in the greenhouse the morning before yesterday.Because it was not sold out yesterday, I got it to sell today.

This is also a common situation in the vegetable market.

Those vegetables that are not sold out on the first day and there are still a lot of them left will be sold the next day.

Ordinary customers would doubt it a few times at most, but there was no sufficient evidence, and the customers did not doubt him, and happily bought it as usual.

To be honest, it was the first time for a female boss like Cheng Nuo to come up with a lot of data to deduce the exact time of vegetable picking.

The point is... so damn right!
Are all high school students this awesome?Can you infer so much just by looking at it?
The female boss deeply doubts whether she went to a fake high school!

Having been exposed naked by Cheng Nuo, the female boss couldn't continue to deceive her.But she didn't want to lose this business, so she smiled awkwardly and said, "Ahem, auntie, although my spinach is not freshly picked. But I dare to say that during the cultivation process, I did not spray any pesticides, absolutely. It is safe, green and pollution-free. Take it back and make soup, it is absolutely safe!"

The female boss is still steadfast in her promise.

"nonono..." Cheng Nuo pushed his glasses, smiled and waved his fingers. "Boss, you made a mistake again."

"The pesticide residue inhibition rate of your spinach is more than 65%. The national standard is 50%. Boss, you have already exceeded the standard by 10%. Why don't you say you didn't use pesticides?" ( Pesticide residue inhibition rate: Under certain conditions, organophosphorus and carbamate pesticides can inhibit the normal function of cholinesterase, and the inhibition rate is positively correlated with the concentration of the pesticide.)
The corner of Cheng Nuo's mouth curled up, looking at the boss with a look of horror in his eyes, he said slowly, "Boss, would you like me to tell you about the brand of pesticide you spray?"

"No need. No need..." The female boss smiled dryly, forced a smile on her face, and said to the grandmother, "Auntie, I really can't afford to offend this young man you brought. You'd better go Check it out somewhere else.”

The female boss is also scared.So many people watching?If Cheng Nuo continued to shake his bottom, the reputation he had accumulated with great difficulty would be wiped out.

The female boss also figured it out. She would rather fail to do this business than get rid of this evil guy Cheng Nuo.

"Okay, then let's go to another house and have a look." Grandma laughed.

Grandma had no doubts about what Cheng Nuo said.Looking at the face of the female boss, one could tell that Cheng Nuo's reasoning was all correct.

It’s not fresh and unhealthy, so what is grandma still doing here?
So I turned around and went to other stalls.

"Xiao Jun, what are you doing there? Let's go." Seeing Jiang Jun standing there, grandma couldn't help but greeted him.

"Oh, here we come..."

Now Jiang Jun's head is dizzy.

After watching Cheng Nuo's pretentious performance just now, a few words kept echoing in Jiang Jun's mind.

Tianxiu! ***!The show of Tihua!Good Fortune Bell Shenxiu!

It was so impressive that the Italian cannon of the second battalion commander exploded!

There is such an operation! !
In Jiang Jun's opinion, wouldn't it be enough to just add, subtract, multiply and divide when going to the wet market to buy vegetables?
After watching Cheng Nuo's operation, Jiang Jun felt that without a college degree in the future, he would not be qualified to come to the vegetable market to buy vegetables!

After not seeing each other for several months, why did his cousin become so... so handsome?
………………

In the end, with the help of Cheng Nuofu's ability, after visiting four or five stalls, grandma finally bought fresh, safe, pollution-free, and scary green spinach.

Then the three of them walked around and finally bought all the vegetables they needed in the area where vegetables were sold.

"Let's go buy some ribs and meat!"

Since grandma promised to cook sweet and sour pork ribs for lunch, the ribs must be indispensable.

So, the three of them walked to the area in the vegetable market that was dedicated to selling meat.

Jiang Jun helped his grandmother carry several bundles of vegetables, and followed behind, wheezing.

Jiang Jun looked at Cheng Nuo, who was walking in front with his hands lightly, with grief and indignation, "Cousin Cheng Nuo, seeing that cousin is so tired, shouldn't he offer to help?"
