Yingying was reading a science fiction novel. She was supposed to read 12 pages a day, but she actually read 8 more pages a day. How many pages was this book? In the end, I finished reading it two days earlier than I did
Assuming that the book has x pages, according to the original plan of reading 12 pages a day, the equation can be written: 12x = y, where y represents the total number of pages in the book. According to the actual situation, if you read 8 more pages a day, you can list out the equation: 12x = y + 8, where y + 8 means that the total number of pages in the book is equal to the total number of pages represented by y. Substituting the y in the first equation into the second equation gives: 12x = y + 8 12x = 12x + 8 y = 18 Substituting y = 18 into the first equation gives: 12x = 18 x = 15 Yingying needed to finish the book two days earlier because she had to read eight more pages per day than the original 12 pages. Therefore, the number of days Yingying spent reading this book was x - 2, which was: x - 2 = 15 - 2 x = -1 Since the total number of pages required in the question is y, we substitute y = 18 into the above formula to get: 18 = 15 - 2 18 = 05 Therefore, this book had 05 pages.
Xiao Ming planned to read 36 pages a day, but he actually read 500 pages in 12 days. How many more pages did he actually read per day?
Xiao Ming planned to read 36 pages a day, but in fact, he read 500 pages in 12 days. 500 pages/12 days = 40 pages/day Because Xiao Ming reads 36 pages a day, the actual number of pages should be 40 pages more than the plan: 40 pages/day- 36 pages/day = 4 pages/day Therefore, Xiao Ming actually read four more pages of novels every day.
Little Ming was reading a storybook. He planned to read 12 pages a day, but he actually read 8 pages a day. In the end, he finished reading it two days earlier. How many pages is this storybook?
Xiao Ming planned to read 12 pages a day, but he actually finished reading 8 pages a day two days earlier. Assuming that this storybook has x pages: - The plan is to read x/12 days, which is x/12 pages. - Actually, x/8 days is x/8 pages. Because Little Ming finished reading it two days earlier, he only needed to read x/8 - x/12 = x/4 days. Because Xiao Ming reads 8 pages a day, he needs to read x/4 days x 8 pages = x 4/5 pages. Therefore, we can get the following equation: x/4 - x/12 = x/5 By solving this equation, one could obtain: x/12 = x/5 + 1/2 x/12 = (x+10)/5 x/12 = x/5 + 1/6 x/6 = 1/6 x = 1 Therefore, this storybook had one page.
Xiaoming read a story book, Xiaofang read a science book. The number of pages in a story book was 75% of that in a science book. Xiaoming read 15 pages a day, Xiaofang read 18 pages a day...
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.
Xiaoming reads a book on the first day, reading 20% of the total number of pages, the number of pages read on the second day and the number of pages read on the first day is 5:4
Xiao Ming read 20% of the total number of pages on the first day of reading a book, which means that the total number of pages multiplied by 20% equals 20% of the total number of pages. On the second day, the ratio of pages read on the first day was 5:4, which meant that half of the total pages read on the second day was 25% of the total pages. Therefore, Xiao Ming read the total number of pages multiplied by 25% the next day, which was equal to the total number of pages multiplied by 5%. Divide the total number of pages by 5 to get the number of pages that Xiaoming read the next day divided by 5. That is, the total number of pages divided by 5 multiplied by 40% equals the total number of pages multiplied by 10%. Therefore, Xiao Ming read the total number of pages multiplied by 10% the next day, which was equal to the total number of pages multiplied by 5.
Xiaoyu was reading a science fiction novel. She had planned to finish it in 45 days, but she actually read 25 pages a day, which was 5 days shorter than her original plan. How many pages is this book?
Let's say the book has x pages. According to the original plan, Xiaoyu needed 45 days to finish reading the book, so she needed to read x pages every day. The actual 25 pages per day was 5 days shorter than the original plan, so the total number of pages that needed to be read was: 45 days/25 pages/day = 18 days Because Xiaoyu read 25 pages more than she originally planned, the total number of pages she needed to read was: 25 pages/day x 18 days = 600 pages So this book is 600 pages.
Cockroach had read 160 pages of science fiction in four days. Which page should he start reading on the fifth day?

How many pages are a fiction book supposed to have?
It really varies. There's no set number. It depends on the genre, the story's complexity, and the author's style.
When Xiao Li read a novel, she would read 74 pages on the first day, 82 pages on the second day, 71 pages on the third day, 63 pages on the fourth day, and more pages on the fifth day than this…
The number of pages read on the fifth day was the number of pages read on the first day plus the number of pages read on the fourth day, which was 74 + 82 = 156 pages. Because the number of pages read on the fifth day was more than the sum of the previous four days, 156 > 4 × 71 + 3 × 63 + 2 × 82 + 1 × 74. Therefore, the answer was that Xiao Li read page 156 on the fifth day.
