Xiaoling was reading a 300-page novel. She had read 80 pages in the first four days. According to this calculation, how many more days would it take to finish the rest of the books?
Xiaoling had read 80 pages in the past four days, so her average reading per day was 80/4=20 pages. The novel had a total of 300 pages. Xiaoling had read it for 4 days and had 240 pages left. Therefore, Xiaoling still needed (240 - 80 pages)/20 pages/day =12 days to finish all the books.
Xiaoling read a 300-page novel and read 80 pages in the first four days. According to this calculation, how many more days will it take to finish reading the remaining pages?
Xiaoling read a 300-page novel and finished reading 80 pages in the first four days, so Xiaoling had 300 - 80 = 220 pages left. Because Xiaoling needed to read 220 pages to finish reading, she needed to read 220/7 = 32 pages every day. Therefore, Xiaoling needed to finish reading the remaining 220 pages in the next 7 days, which meant that she needed 220/32 = 6 days. Therefore, Xiaoling needed to read 32 pages a day for the remaining six days to finish the novel.
Chubby Boy read a 150-page storybook. He read 15 pages on the first day, and then read two more pages every day than the previous day. According to this calculation, seven days a week, could he read
The 150-page storybook was two pages more than the previous day, which meant that he would read 30 pages more every seven days. Fatty read 15 pages on the first day, so the number of pages he read on the seventh day was: 15 + 15 + 15 + 15 + 15 + 30 = 100 pages Therefore, Lil 'Fatty could finish reading 100 pages of storybooks in seven days a week. However, this did not mean that he would be able to finish the book. Reading two more pages a day meant reading nine more pages every four days. The book had 150 pages, so before the 10th day, Chubby Boy might have read 15 more pages, which would make it impossible for him to finish the book.
Xiao Ling read a 290-page novel. For the first four days, she read 20 pages a day. From now on, he would be able to finish reading 30 pages a day in a few days.
You can use the following formula to calculate the number of days it will take Xiao Ling to finish reading this novel: Days = total page count/page count for the first 4 days + 1(add 1 day later) Total pages = 290 pages The number of pages read in the first 4 days = 20 pages/day × 4 days = 80 pages/day Therefore, the total number of pages that Xiao Ling needed to read was 290, and she had read 80 pages a day for the first four days, totaling 480 pages. Next, Xiao Ling needs to read 30 pages/day in the next day, so she still needs to read 480 pages/30 pages/day = 16 days Therefore, Xiao Ling needed 16 days to finish reading this novel.
Li Xin wanted to read a 600-page children's fairy tale. She planned to finish it in 12 days, but she actually read 40% in 6 days. According to this calculation, Li Xin could finish reading it in a few days…
According to the topic, Li Xin planned to finish reading Children's Fairy Tales in 12 days, but in fact, she read 40% in 6 days. Then the number of pages he read in the first six days was: The number of pages read in the previous 6 days/total number of pages = 40%/600 = 0067 In other words, the number of pages he read in the first six days accounted for 0.67% of the total number of pages, which was six pages. Therefore, Li Xin needed to choose 5 out of the 6 pages to be his main text, and the remaining 1 page could be used as a reference or an attachment. For the remaining page, he needed to calculate how many pages he needed to read every day: 1 page × 6 days = 001667 Because the total number of pages that needed to be read every day was six, so: 001667 ÷ 6 = 0002833 He needed to read page 0002833 every day. Therefore, Li Xin needed to read page 0002833 every day for the next 6 days to finish the last page. If you want to calculate the total number of days you need to read, you need to multiply the total number of pages you need to read per day by the number of days: (0002833 ÷ 6) × 12 = 0004867 Therefore, Li Xin needed 12 days to finish reading Children's Fairy Tales.

Fang Fang had read a 250-page storybook, and she had read 75 pages in the past three days. Based on this calculation, how many days would it take for her to finish reading this book?

Kobayashi was reading a 290-page novel and planned to finish it in seven days. In fact, he had only read 20 pages a day for the first four days. How much should he read every day after finishing it according to his plan?
Kobayashi planned to finish a 290-page novel in seven days, but in fact, he only read 20 pages a day for the first four days. How many pages should I read every day after finishing this book as planned? Since he only read 20 pages a day, Kobayashi had already read 290 - 20 = 270 pages by the sixth day. The remaining pages were 290 - 270 = 10 pages. Therefore, Kobayashi needed to read 10/7 = 167 pages of the remaining 10 pages every day. Because he had to read a certain number of pages every day, Kobayashi needed to read 167 pages more than his original plan to complete the reading plan on time. Therefore, Kobayashi needed to read 10 + 167 = 1167 pages instead of the original 10 pages on the seventh day.
