Because the second question gave him a warning, Lu Sanlang, who had just thought the first question was easy, no longer dared to underestimate these questions. He took down the bamboo boards one by one, looked at them carefully, and hung them back one by one, his brows furrowed.
Liu Yin originally planned to continue watching the fun from the sidelines, but when Qi Liang couldn't hold back and winked at her for the third time, she finally said reluctantly and slowly, "Mr. Lu San, take your time to solve the problem. I'm leaving first. If I don't go back, the young lady won't be able to find me and will be angry."
"Okay, take care." Lu Sanlang said this, but his eyes didn't move away. Anyway, he didn't really want to please Miss Zhu, so he didn't care what Liu Yin thought of him.
It’s best not to be there, he can still concentrate on solving the problem!
At this moment, he took back the second bamboo card and racked his brains to think about the solution to this problem. He was the youngest son that his father disliked the most, although he was the most beloved by his mother. However, he thought that he was born with talent and would be useful. He would make it back even if he lost all his money. However, he never found a good opportunity.
He didn't expect to take the exams to become a scholar, a juren or a jinshi, but as a person who was the best at mental arithmetic, he didn't believe that he couldn't solve these math problems!
When Zhang Shoudang in the bamboo house found that Liuyin turned away in annoyance, he was too lazy to hide his figure. He quietly moved to the window and looked at the fat and big-eared boy with interest.
In his initial conception, Lu Sanlang, the suitor that Zhu Ying disliked, should be a playboy who was well-fed all day long. He was just relying on his father's official position and his mother's favor, and was obsessed with the beauty of the rich girl, so he was so persistent.
So when seeing those difficult problems, this person's reaction should not be like this.
Lu Sanlang shouldn’t have been so angry and yelled—what do these questions have to do with the Four Books and Five Classics? Is this what a human did
Suddenly, he heard Lu Sanlang ask without even looking up: "Which problem did Miss Zhu solve?"
Qi Liang, who had been standing behind Lu Sanlang calmly, was stunned. He looked up in the direction of Zhang Shou and saw the young master smiling and nodding at him. He immediately replied in a very casual tone, "It's the first question that Mr. Lu San has seen."
"No wonder!"
Lu Sanlang then smiled with satisfaction and said as if no one was around, "I think she can only answer questions of that difficulty at best."
"The first question is very simple. The two carts traveled a total of 170 miles a day. On four of those days, they traveled for four full hours, which means a total of 680 miles. On the other three days, they traveled for only three hours a day, so the distance they traveled was naturally three quarters of the distance they traveled on each of the previous four days. Adding it all together, it's 382 and a half miles."
"So, the distance between the two cities is easy to calculate. It's a total of 1,062 and a half miles."
Qi Liang was not too surprised to hear this answer, so he nodded and said, "Yes, Mr. Lu San got this question right."
He felt that this was an easy question for the young man!
Lu Sanlang looked unhappy and coughed softly again.
"The second question is a little bit harder, but it's not that difficult. The water inlet pipe takes in one-fifteenth of the entire pool every hour. The water outlet pipe takes out one-twenty-fourth of the entire pool every hour. First, only let the water in for two hours, so the water in will be two-fifteenths. Then, open both pipes at the same time, one in and one out, and the water in one hour will be one-fortieth of the entire pool."
