"There is a flock of chickens and a flock of rabbits in the same cage, with a total of fifteen heads and forty legs, may I ask, how many chickens are in the cage? How many rabbits are there?"

"You...... How do you know this Olympiad question......"

In front of everyone's eyes, Chef Pierre's eyes suddenly tightened, and his face was full of incredulity.

Seeing Pierre's shocked expression, the onlookers were stunned.

Could it be that Ma Xiaozhen said it again?

Ma Xiaozhen's face was full of sadness and joy, like a swordsman who was against a peerless master, like a dragon and a mountain, slowly took a step towards Pierre and continued to ask.

"Excuse me, it takes 6 hours to fill a 50 cubic meter A pipe in a certain pool, 10 hours to drain B pipe, and how long does it take for AB pipe to be filled with water at the same time?"

"This ......"

Pierre's face instantly turned pale, and he couldn't help but take a step back as if he was facing a great enemy.

Ma Xiaozhen took advantage of the victory to pursue and took another step forward.

"Let me ask again, what color is this bear when it accidentally falls into a big pit and falls at a speed of 10 meters per second?"

"You...... You ......"

Looking at the aggressive Ma Xiaozhen, Pierre was like a ghost, and even took a few steps back, his face full of horror: "You...... How do you ......?"

At this moment, the onlookers all had a sense of confusion like a mystery.

What's going on?

What is the rhythm of this?

Big brothers, what the hell are you doing?

It's going to be fast.

First it was the God of Food Competition, and then it instantly became the anorectal department of the old Chinese medicine medicine, and then it became the Sparrow God Competition, and now it is good, and it has directly crossed into the scene of the Olympiad Mathematics Gold Cup for primary school students......

It's like when you're about to enjoy a "The Marriage of Figaro" at the WYN Opera House, but what comes to the stage is a Northeast two-person turn, and then it is instantly replaced by a green onion song in the vegetable market, and finally it becomes the most famous music in the resettlement community in the east of the city-

The Jiangnan Tannery has closed down! The boss of the bastard, the bastard, the yellow crane! Eating, drinking, gambling, eating, drinking, prostitution, gambling, owing 350 million yuan! Running away with his sister-in-law! We have no way! Take our wallets to pay for wages!

This rhythm comes too fast, like a tornado, and it is impossible to escape without the storm......

There was a feeling of rollover in all of them.

However, only the person concerned, Mr. Pierre, knew how big a wave Ma Xiaozhen's three questions of the Olympiad math problem fell in his ears.

It was like a thunderbolt in the clear sky, and like a dusk drum and morning bell, which made him physically and mentally shaken and deafened!

Only he knows that these Olympiad questions are exactly where the entanglement in his heart lies in the past few days.

Looking at Pierre's shocked expression, Ma Xiaozhen shook his head lightly and said softly:

"If I'm not mistaken, Monsieur Pierre, your wife is from Great Xia. ”

Pierre nodded slowly.

Pierre is a Frenchman, who has always looked down on the men of the Great Xia Kingdom, thinking that the men of the Great Xia Kingdom are rude and rude, do not understand the subtlety of French food, and call them Oriental monkeys at every turn. But he met a woman named Ma Xiaoli a few years ago, and was deeply attracted to this oriental woman, and finally got married.

After the two got married, Ma Xiaoli missed her hometown. The French were born romantic, and for the sake of his wife, Pierre resolutely resigned from his position as the head chef of a three-Michelin-starred restaurant in France, accepted the invitation of Zhou Pengfei's father Zhou Yunhai, and brought his team of chefs to Changzhou in the Great Xia Kingdom.

Seeing Pierre nodding, Ma Xiaozhen continued.

"After you and your wife got married, we had a child, who is 10 years old. Classes are held at the Primary School Affiliated to the National Normal University in Cheung Chau. ”

"Nowadays, children are under a lot of pressure, and your wife insists on sending your children to Olympiad math training classes, but you don't agree, you think that children should play happily. What's more, elementary school math, as long as you teach it at home. ”

"So your wife made a bet with you, she randomly selected three Olympiad questions, as long as you can answer them, you won't send them to the Olympiad class, but if you can't answer them, then send them to the Olympiad class!"

"These three math problems are the three I just said!" Speaking of this, Ma Xiaozhen suddenly shouted: "Right?"

“...... Right. ”

Pierre was silent for a while, and finally nodded slowly, and the corners of his eyes suddenly began to moisten.

He thought it was just a mere elementary school math problem, but for an adult, it was like an anti-aircraft gun fighting mosquitoes, which was overkill, and it was simply not worth mentioning.

But I didn't expect it, I never thought of it.

Pierre couldn't answer a single question.

Nima!

Elementary school math problems are so perverted!

It's a fucking extermination of humanity! It's a fucking horrific death!

Pierre burst into tears.

It's a goddamn shame.

"Your math problems in the Great Xia Kingdom are really too perverted. Pierre cried and said, "Devil, you are all devils......"

"No...... We are not the devil. Ma Xiaozhen shook his head gently: "This is just the most basic elementary school student Olympiad question in the Great Xia Kingdom! ”

"No! no way!" Pierre shook his head frantically: "How can such a difficult math problem be the most basic elementary school student Olympiad problem?"

"If you don't believe me, I'll teach you. ”

Ma Xiaozhen swept Pierre with a compassionate gaze and explained.

"First, the chicken and the rabbit have fifteen heads and forty legs. Suppose both the chicken and the rabbit are able to understand commands. When a whistle is blown, they raise one foot, and that is (40-15) equals twenty-five feet. One more whistle blows, and they raise one more foot, which is (25-15) equal to ten feet. ”

"At this time......" Ma Xiaozhen explained confidently, "the chickens are all sitting on the ground, and the rabbits are still standing on two feet." So, rabbits have 10/2 = 5 and chickens have 15-5 = 10. ”

Pierre's face turned pale.

"In the second question, the water injection efficiency of pipe A is 50/6, and the drainage efficiency of pipe B is 50/10, then the time required is 50 divided by (50/6-50/10), that is, 50 divided by 10/3, and the answer is 15 hours. ”

Pierre's face was pale.

"The last question is actually simpler," Ma Xiaozhen said aloud, "When a bear is at the South Pole and the North Pole, its falling speed is different from that in other places. The speed of the fall is 9.8 m/s elsewhere, and it is definitely faster at the North and South Poles. And there are no bears in Antarctica, only in the Arctic there are polar bears. ”

Pierre's face was like dead wood.

"So, the color of the bear should be ......" Ma Xiaozhen looked at Pierre, and a touch of pity appeared on his face: "White." ”

"Bang-"

Pierre, like Basille and Powers, sat down on the ground with an unbelievable expression on his face.

Ma Xiaozhen looked down on Pierre condescendingly, like a god of war, and said loudly.

"My Great Xia Kingdom, the quality education of the Celestial Empire, is unparalleled in the world!

Ma Xiaozhen's words were deafening, and the aftermath lingered.

The scene once again resounded with long-lasting applause.

At the same time, the screaming chicken on Ma Xiaozhen's pants also emitted agitated music.

"Great Xia Red Flag, you are my pride! Great Xia Red Flag, I am proud of you! Cheers for you, I bless you! Your name is more important than my life!"
