Chapter 1357: Revealing His Edge
Lin Yuelan nodded and explained," In our hometown, when we encounter such a problem, we usually use the replacement method."
"Replacement method?" Everyone was puzzled.
Lin Yuelan continued," In Longyan Country, there"s a language called Pinyin. This Pin yin table has a, b, c, etc. 26 single letters."
Lin Yuelan slowly explained the answers.
"These 26 letters are unknown numbers in mathematics. Therefore, the question given by the high priest just now, the price of the rooster, hen, and chick was 5 wen, 3 wen, and one-third of the price, respectively. So, this formula became: 5x+3y +1/3z =100. In this hypothesis, another integral number k was set. Then, x=4k, y=25- 7k, z=75+ 3k.
"Because x, y, and z can only be positive numbers, the k value that can satisfy this set of equations can only be 1, 2, 3…Using 1, 2, and 3 to replace k in the equation, the answer would naturally be 4 roosters. Four roosters were worth 20 wen, and three chicks were worth 1 wen. So there were seven chickens for 21 wen. You can also purchase seven hens for 21 wen. If you didn"t buy the seven hens, then you could use the same money to purchase four more roosters and three more chicks. In this way, you will have a hundred chickens for a hundred wen.
"Therefore, as long as one answer was obtained, other answers could be obtained immediately according to this law."
To the people of Longyan, they were already very familiar with the 26 letters.
Moreover, no one present was a fool. Therefore, they immediately understood what was going on after Lin Yuelan"s explanation.
However, for the foreign guests who were not familiar with the alphabet of the Longyan Country, listening to Lin Yuelan talk about numbers like x, y, z... They really couldn"t understand it.
However, when they saw the people of Longyan Kingdom nodding their heads to show that they understood what was going on, their hearts were filled with bitterness, and their faces were a little embarra.s.sed.
If they admitted that they didn"t understand, wouldn"t it prove that they were dumber than the people of the Longyan Kingdom? But they couldn"t pretend to understand it either.
However, the only thing they understood was that what Lin Yuelan said was the correct answer given by Liang Renhui.
In the end, Lin Yuelan smiled and asked," High Priest, do you think I"m right?"
Liang Renhui was also confused by Lin Yuelan"s explanation. However, the ancient book recorded that there were 4 roosters, 18 hens, and 78 chicks.
Liang Renhui a.s.sumed that Lin Yuelan was only talking big.
He had already planned to humiliate the Longyan Kingdom when the so-called princess of the Guguo didn"t know the answer to the question. Then, he would propose a marriage alliance.
Of course, the marriage partner was the princess of Guguo.
At this moment, the princess of the Guguo had explained the answer clearly. Looking at the expression of Longyan Kingdom"s ministers, he couldn"t deny the answer even if he wanted to.
Liang Renhui smiled and said," Princess Gu is really smart. I really admire you!"
Lin Yuelan said humbly," High Priest, you"re flattering me! However," she changed the topic and asked with a smile," High Priest, do you know that there are other answers to this question?"
When Liang Renhui heard this, the smile on his face immediately froze. Then, he asked with a fake smile," Really? Then I"m all ears!"
However, he was cursing in his heart. Lin Yuelan must have done it on purpose.
Just now, he deliberately said that he couldn"t understand this question, no matter how much he thought about it. His ultimate purpose was to make things difficult for the monarch and minister of the Longyan Kingdom.
But now, not only had this question been solved, but there were also other answers that he did not know.
Wasn"t this a slap to the face of the person who set the question?
Therefore, his expression turned a little ugly. He really hoped that Lin Yuelan would shut her mouth!
However, since he had offended Lin Yuelan, could she shut up?
Of course not.
Lin Yuelan continued," Also, one can use the three-dimensional infinitive equation to solve it. Using the numbers 1, 2, 3, 4…Putting them into the formula, one could get the 4 roosters, 18 hens, and 78 chicks. You could also go with 8 roosters, 11 hens, and 81 chicks. Or 12 roosters, 4 hens, 84 chicks, and so on. As long as one followed this formula, there would be more answers."
