Father, I am back to fight!

Chapter 107

"Didn't you understand? You just said that if I can solve the eternal mystery of the pagoda, this golden pagoda will be given to me!"

"And what this prince just said is the answer to this eternal mystery!"

Qin Yu said coldly.

The golden pagoda is more than one meter tall, and the unsolved mystery of the ages is engraved on the most conspicuous place on the tower, which Qin Yu can see clearly.

But when he saw the title of the eternal mystery, he was completely speechless. It turned out to be the most famous chicken and rabbit in the same cage in later generations, except that the number was slightly larger!

There are chickens and rabbits in the same cage. Looking from above, there are 3,700 heads, and looking from below, there are 10,120 feet. How many chickens and rabbits are there?

This was indeed a difficult problem in ancient times, but in later generations, it was a problem that even elementary school students could solve, so he directly gave the answer.

"Haha! The answer that Your Highness just gave is indeed the answer to this eternal mystery. I once summoned hundreds of experts in mathematics and spent five years to deduced the answer!"

"Although I don't know where His Royal Highness the Crown Prince learned this, this eternal mystery can't be solved simply by stating the answer. You also need to explain the solution!"

"Your Highness, please stop embarrassing yourself here!"

Hu Yanqing said with a sneer, his eyes full of disdain, and directly said that the answer calculated by Qin Yu was something Qin Yu knew from somewhere that he had someone calculate.

"Haha! This prince didn't know the answer to this question from somewhere, but calculated it. Therefore, this prince naturally has a solution!"

Qin Yu said with a sneer.

what!

After hearing what Qin Yu said, all the officials present were shocked!

They also saw the eternal unsolved mystery on top of the pagoda, the difficulty of which made their scalps tingle!

If this question just requires you to give the answer, it is actually not unsolvable. As long as you try one number at a time, you will always get the answer.

However, it also states that there must be a method to solve the problem. In this way, the difficulty is not just increased by a hundred or a thousand times, but by hundreds of thousands of times!

Qin Yu not only gave the answer, but also said that there was a way to solve the problem. This was simply amazing!

Emperor Liang's eyes became even deeper. Qin Yu's speaking of Arabic numerals and the multiplication table had already shocked him greatly. He didn't expect that Qin Yu could even solve this eternal mystery!

How many secrets is this kid hiding from me?

"Then I'm all ears! However, I've also made it clear that if Your Highness the Crown Prince can't come up with a solution, you must apologize to me!"

Hu Yanqing said coldly.

He really wanted to use the same trick again and use this incident as an excuse to take back the State of Chu.

However, he was also very clear that Emperor Liang and the officials present were not pushovers, so he chose to let Qin Yu apologize to him, at least to save some face!

"The solution is simple. Let's assume the chicken is D and the rabbit is B. Since both rabbits and chickens have only one head, D plus B equals 3,700!"

"Similarly, because chickens have two legs and rabbits have four legs, D times two plus B times four equals 10,012!"

"From this, we can conclude that D plus B plus B times two equals 10,012, and D plus B equals 3,700, which means 3,700 plus B times two equals 10,012!"

"Three thousand and seven times is seven thousand and four. Double of B is ten thousand and twelve minus seven thousand and four, which is two thousand seven hundred and twelve. Divide twice, and it equals one thousand three hundred and six!"

"We figured out the number of rabbits is 1,306. So, we just need to subtract 3,700 from the number of chickens, and we get 2,394!"

Qin Yu said in a deep voice.
