Little Light started reading a novel on January 5th. If he reads eighty pages a day, he will finish it by January 9th; if he reads ninety pages a day, he will finish it by January 8th...
If Little Light started reading 80 pages a day from January 5th, he would need to finish 1/8 of the novel on the 10th day. Therefore, Little Light needed to finish reading the novel on January 12th. If Little Light read 90 pages a day, he would need 16 days to finish 1/8 of the novel, which was 120 pages. Therefore, Little Light needed to finish reading the novel on January 16th.
Little Light started reading a novel on January 5th. If he read 80 more pages a day, he would finish it on January 9th. If he read 90 pages a day, he would finish it on January 8th.
If Little Light started reading a novel on January 5th, he would finish it by January 9th, and if he read 90 pages a day until January 8th, then what day would Little Light finish it? Assuming that the number of pages in the novel is X, then the number of pages Little Light reads every day is X+80, then the total number of pages he needs to read is (X+80)×28 days. (X+80)×28 = X×28 + 80×28 To simplify it: X = 5200 Therefore, the number of days Little Light needed to finish reading could be calculated by the following equation: (5200+80)×28 = 5200×28 + 80×28 504000 = 104000 Little Light needed to finish reading on the 104th day.
Wang Liang started reading a novel on January 5th. If he read 80 pages a day, he would finish it on January 9th. If he read 90 pages a day, he would finish it on January 8th.
If Wang Liang reads 80 pages a day, he will be able to finish the first part of the novel by January 9th. If Wang Liang reads 90 pages a day, he will be able to finish the first part of the novel on January 8th, but he will need an extra two days to finish the whole novel. Therefore, if Wang Liang started reading a novel on January 5th, he would need an extra five days (January 9th to January 14th) to finish reading the entire novel.
If Little Ming reads a book, if he reads 15 pages a day, he will finish it in 24 days. If he reads 20 pages a day, how many days will he finish it?
Xiao Ming reads a book. If he reads 15 pages a day, he will finish it in 24 days. If he reads 20 pages a day, how many days will he finish it?
If Xiao Ming reads 15 pages a day, the total number of pages he needs is: 15 pages/day x 24 days = 360 pages Therefore, Xiao Ming needed to read 360 pages to finish it in 24 days. The number of days required to read 20 pages a day is: 20 pages/day x days = 20 days Therefore, Xiao Ming needed to read for 20 days to finish the book.
Little Light is reading a novel. He plans to read 20 pages a day, but he actually reads 25 pages a day. This way, he can finish reading it three days in advance. How many pages is this novel?
Assuming that the novel has a total of n pages, according to the plan, Little Light needs to read n/20 pages, which means n/20 = 1 or n/20 =-1. This depends on whether the total number of pages in the novel is even or not. If n is an even number, then n/20 is an even number, and 1 and-1 are both even numbers, so n/20=1. The number of pages Little Light needs to read is n/20=n/2, which is n=40. If n is an odd number, then n/20 is an odd number, and 1 and-1 are both odd numbers, so n/20=-1. The number of pages Little Light needs to read is n/20=-n/2, which means n/2=-40, so n=-80. In summary, the novel has a total of 40 or-80 pages.
If Xiao Qiang reads a literary masterpiece, if he reads 20 pages a day, he can finish it in 18 days. If he reads 5 pages less a day, how many days can he finish it?

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.
Xiao Ming reads a book with a total of 125 pages. He reads 10 pages a day, starting from August 20th. Can he finish reading this book before September 1st?
It is difficult to accurately predict whether Xiao Ming will be able to finish reading the 125-page book between August 20th and September 1st. This is because the speed of reading, the time spent reading, and other factors may affect his progress. However, we can do some analysis and estimations. Reading 10 pages a day meant that Xiaoming would need to spend about 125 days a day to finish reading a 125-page book. Taking into account the time he can spend every day, we can cut this time in half, which is 275 days a day. The number of days that Xiao Ming needs to read between August 20th and September 1st is: August 20-August 29 = 5 days August 30-September 5 = 5 days September 6-September 10 = 3 days September 11-September 15 = 2 days September 16-September 18 = 1 day September 19-September 23 = 2 days September 24-September 27 = 1 day Therefore, Xiao Ming needed to spend about nine days to finish reading the book before September 1st. Although this estimation result is not accurate to the end of the day, it can help us roughly predict whether Xiao Ming can complete the reading task within the specified time.

If Mao Mao reads a book and reads 30 pages a day, he can finish it in 8 days. If he reads 40 pages a day, how many days can he finish it in advance? Use the ratio method to answer
Mao Mao reads a book and reads 30 pages a day in 8 days. Therefore, the total number of pages in this book is 30 × 8 = 240 pages. If I read 40 pages a day, how many days can I finish it in advance? Using the ratio method to answer: To calculate the number of days you can read 40 pages a day compared to 30 pages a day, you can use the ratio method: Reading 40 pages a day was 40 - 30 = 10 pages more than reading 30 pages a day. Therefore, the number of days required to finish reading this book was 240 pages/10 pages/day = 240 days. Substituting this result into the original formula: 8 days/240 days = 0037125, which meant that reading 30 pages a day was about 37125 days earlier than reading 40 pages a day. Therefore, by reading 40 pages a day, he could advance by 0.037125 + 37125 = 47125 days. The answer was about four days in advance.
