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

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.

The novel was called "One Hundred Years of Solitude" by Colombia Márquez. According to the plot of the novel, Ling Ling would be able to finish reading the novel in ten days. Reading three more pages a day than the day before meant that the length of the novel would increase by three pages every day. Therefore, within 10 days, the length of the novel will increase to: 10 days x 3 pages/day = 30 pages Therefore, Ling Ling needed to read 30 pages of the novel in 10 days. If Ling Ling had this novel, she could start reading it on the first day and then read three more pages each day until she finished reading it.

Lili spent 8 days to finish reading a storybook. She read 150 pages in the first 3 days and 42 pages a day in the next 5 days. So she read a total of $150/times 3 + 42/times 5 = 2220$pages. And the total time she spent was $8$days, so she read an average of $2220 / 8 = 265$pages per day. So Lili read an average of 265 pages a day.

Zhang Li read a book of 80 pages. On the first day, she read 35% of the book, and on the second day, she read 1/4 of the book. How many pages did she read in two days? On the first day, he read 35% of the book, which was 80 pages x 35% = 28 pages. The next day, he read 1/4 of the book, which was 80 pages x 1/4 = 20 pages. Therefore, the total number of pages he read in two days was 28 + 20 = 48. Answer: 48 pages in two days.

Let's say the book has $x$pages. The original plan was to read $12$pages a day, so it would take $x$Mum $12$days to read the entire book. In fact, it would take an extra $8$a day to read the entire book, so it would take $x$Mum $12$ + $2$days. Because Xiao Ming finished the book two days earlier, he actually spent $x$Mum $12$ + $2$ - $1$days to finish the book. We can solve this problem by using the exponential sequence sum formula: $$x \div 12 + 2 - 1 = \frac{x \times (12+2)}{12}$$ The solution is $x=300$. Therefore, the book had a total of $300$pages.

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.

There was a total of $12/15 - 1/15 = 165$pages left in the storybook. After reading the remaining two-sevenths, the remaining pages were two-sevenths of the original number. Therefore, he still needed to look at $165/div2/7 = 105$. Therefore, there were still 60 pages left.

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.

On the first day, Xiaofang read the book's 51 pages, and the remaining pages were $51/div2 = 25$. The next day, he read another 10 pages and the remaining pages were $25 + 10 =$35. At this point, the ratio of pages seen to pages not seen is 2:3, which can be expressed as $25:35=2:3$. Therefore, Xiaofang had read the book for $2+3=5$days and still had $35-5=28$pages left.

The book took 11 days to finish because 30 pages were read on the first day. The remaining pages were: 30 pages/day = 30/day The number of pages left every day was 60 - 30 = 30 pages. Therefore, the book would take 11 days to read, 30/day x 30 pages = 900 pages.
