If Xiaoming reads a novel and reads 35 pages a day, he will finish the book one day later than the stipulated date. If he reads 40 pages a day, he will read 5 pages less on the last day…Xiao Ming reads a novel. If he reads 35 pages a day, he will finish the whole book one day later than the stipulated date. If he reads 40 pages a day, he will read 5 pages less on the last day.
We can set the total number of pages of the novel as x and the specified date as d, then the total number of pages that Xiaoming needs to read is x/35 + x/40 - 1.
According to the question, Xiaoming needs to read d books, so there are:
x/35 + x/40 - 1 = d
Transferring the terms of the equation gave:
x/100 = d
Therefore, Xiao Ming needed to read 100 pages a day to finish the novel by the stipulated date. If you read 35 pages a day, you would need an extra two days to finish the novel. If you read 40 pages a day, you would need an extra three days to finish the novel.
After considering all, Xiaoming needed to read 37 pages a day to finish the novel according to the stipulated date. On the last day, he had to read 5 pages less.
If Xiao Ming read 35 pages a day, he would finish the book one day later than the stipulated date. If he read 40 pages a day, he would have to read 5 pages less on the last day.Xiaoming reads a novel. If he reads 35 pages a day, he will finish the book one day later than the stipulated date. If he reads 40 pages a day, he will read 5 pages less on the last day.
Based on this information, we can formulate the following equation:
Let the total number of pages in the novel be x Xiaoming reads x/35 days, that is, he reads x/35 pages every day.
Because Xiao Ming needed to finish reading the entire book, he needed to meet the following two conditions:
Xiaoming finished reading the novel before the stipulated date
2 Xiao Ming reads 35 pages a day, so the total number of pages read is 35x/12 days
Therefore, we can write the following equation:
x/35 = (x/12) - 1
Solve the equation:
x = 35x/12 + 1 = 40
Therefore, Xiao Ming needed to read 40 pages to finish the novel. He needed to read 40/35=8/17 days before the specified date. However, because reading 40 pages a day is slower than reading 35 pages, the actual time he needs will be longer than 8/17 days, that is, he will need 16/17 days to finish reading the novel.
A 600-page book. Every day, he would read one more page than the day before, and he would finish it in 16 days. How many pages did you read on the last day?If the number of pages of the book is x, then the first day is x/page, the second day is (x/page)/2, and so on, the 15th day is (x/page)/16.
Because I read one more page every day than the day before, the number of pages I read in 16 days can be expressed as:
(x/page)/16 + (x/page)/17 + (x/page)/18 + + (x/page)/15
This is a geometric sequence and the sum is x/page. Therefore, the common ratio of this exponential series is 16, and the first term is x/page.
By replacing x/page with the first term of this exponential sequence, we get:
(x/page)/16 + (x/page)/17 + (x/page)/18 + + (x/page)/15 = x/page
To simplify it:
(16x/15)/16 = x
Solution:
x = 600
Therefore, the book had 600 pages.
Give me an article of more than 10,000 words and I'll paste it. Thank you.Of course, I'm happy to share a novel with you.
