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.
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.
He was going to read a 158-yuan story book, but he read 16 pages a day. If he started from July 25th to August 3rd, would he be able to finish reading it?
The total number of days required to finish reading a 158-page storybook is: 158 pages/16 pages/day = 105 days There were 30 days from July 25th to August 3rd, so: 30 days/105 days/day = 2875 Because the total number of pages per day was 16, so: 158 pages/16 pages/day = 105 days Therefore, he had to read 16 pages a day from July 25th to August 3rd to finish the 158 pages of the storybook.
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.
Xiao Ya planned to finish reading a book in 20 days and read 15 pages a day. If he read five more pages a day, how many days would he be able to finish it?

Li Xiaolin was reading a storybook. If he read 12 pages a day, he would finish it in 15 days. If he had to finish it in 10 days, how many pages should he read on average every day?
If you can finish a storybook by reading 12 pages a day and 15 days, then the average number of pages in this storybook is: 15 days/ 12 pages/day = 15 pages/day Therefore, if Li Xiaolin wanted to finish reading this storybook in 10 days, he should read it on average every day: 10 days/ 15 pages/day = 6 pages/day In other words, Li Xiaolin should read 6 pages a day instead of 12 pages a day.
If Xiao Sen read 30 pages a day, he could finish it in 20 days. If he wanted to finish it in fifteen days, he would have to read forty pages a day.
If Xiao Sen read 30 pages of a literature book every day for 20 days, he could finish it. If he needed to read 40 pages a day to finish it in 15 days, then his reading speed should be 10 pages more per day. The calculations were as follows: 20 days x 30 pages/day = 600 pages 15 days x 40 pages/day = 600 pages Reading 10 more pages per day, the total number of pages required is 600 pages/(30 pages/day + 40 pages/day) = 600 pages/70 pages/day = 88 days Therefore, Xiao Sen needed to read 10 more pages every day, which was about 88 days, to finish reading this literary book.
Li Ming was reading a 225-page novel. For the first five days, he would read 24 pages a day, and then 35 pages a day. How many more days would he need to finish this novel?
Li Ming read a 225-page novel. For the first five days, he read 24 pages a day and then 35 pages a day. The calculation is: 100 pages in the first 5 days, the remaining pages are 225-100=125 pages. Reading 24 pages a day required 125/24=5 days. Reading 35 pages a day required 125/35=4 days. Therefore, Li Ming needed 5+4=9 days to finish reading this novel.
