Chapter 666: Setting Questions (2)
Translator: Dragon Boat Translation Editor: Dragon Boat Translation
Mo Fei and the other two also looked at Liu Wuji with uncertainty in their hearts.
They did not solve this question.
However, after the Imperial Advisor’s explanation, they realized that this question was actually not difficult.
Chu Jin’s envoy was also an expert in arithmetic. What if he could also think like that?
In that case, would he have solved the problem?
The Imperial Advisor pondered for a moment.
“This is just a backup. The difficulty of this question is not high enough. He might be able to solve it.” He said.
Seeing Lin Xiaoyue’s disappointed expression, Liu Wuji added, “don’t underestimate the ability of Xu Yan and the others. If I can solve the problem, it shouldn’t be a problem for him to solve it.”
Lin Xiaoyue was shocked.
The opponent was so strong?
Lin Xiaoyue glanced at the Imperial Advisor and saw his serious expression. She didn’t say anything else.
It seemed that the probability of this question stumping the opponent was not high.
After thinking for a while, Lin Xiaoyue came up with a new question.
Therefore, she asked Liu Wuji to record it.
The Imperial Advisor was very interested and quickly made his preparations.
The few people who were going to go back to work also stayed behind, waiting to hear Lin Xiaoyue’s new questions.
Lin Xiaoyue’s gaze swept across everyone’s faces. She then said, “there’s a job.
If both A and B work together, it will take 8 hours to complete.”
“If B and C work together, it will take 10 hours.”
“Now, if A and C work together for 2 hours and leave the rest to B. B will need another 12 hours to complete.”
“The question now is how long it will take for B to complete this task alone.”
Liu Wuji wrote the question down and everyone looked at it.
Liang Chengcai and the others didn’t even wait for the Imperial Advisor’s instructions. They took a pen and paper and started to calculate the questions.
Unfortunately, after looking at it for a long time, it was the same as the previous question. They did not know where to start.
Liu Wuji also frowned and did not speak for a long time.
After a while, he finally stopped looking at the questions and looked up at Lin Xiaoyue.
“This question is the same as the one you gave to the Sixth Princess. If it’s the same type of question, only one question can be given.”
He hadn’t thought of a way to solve the previous question.
Now that he encountered this problem again, he naturally couldn’t solve it.
Lin Xiaoyue smiled. “What if the method of solving is different?”
Liu Wuji was stunned.
“Why don’t you tell me how to solve this problem? Tell us more about the solution to the previous question.”
“Whether or not they are the same is up to one’s judgment.”
The rest of the people also looked at Lin Xiaoyue, very curious about how to solve this kind of question.
Lin Xiaoyue nodded.
“Alright then.”
Then, she looked at the questions on the table.
“Let’s talk about the algorithm for this question first.”
“If A and B work together, they can finish it in 8 hours. So they can complete a quarter of the total work in 2 hours.”
Lin Xiaoyue only recently learned that they understood fractions, but this method of calculation was not widespread.
As some of the strongest people in the Great Yan, Lin Xiaoyue did not doubt that everyone here knew fractions.
Sure enough, after hearing Lin Xiaoyue’s words, everyone nodded.
Lin Xiaoyue felt better. She continued, “similarly, B and C can complete one-fifth of the total project in 2 hours.”
Everyone nodded again.
“Next, A and B work together for 4 hours to complete two-quarters of the work. Similarly, B and C work together for 4 hours to complete two-fifths of the work.”
“In total, they have completed 90% of the work.”
As everyone listened, they calculated in their hearts.
After confirming that the calculation was correct, they all nodded.
“If we look at it separately, A and C each took 4 hours, while B took 8 hours.”
“At the same time, we also know that A and C working for 4 hours and B working for 12 hours will finish the work.”
“In other words, B only needs to work for another 4 hours to complete the remaining one-tenth of the project.”
“In this way, it can be easily calculated that B can only complete one-twentieth of the work per hour.”
“That’s the solution. If this job is given to B alone, it will take 20 hours.”
Everyone was surprised..
