Wang Jun read a book, 24 pages a day. He finished half of the book in six days, and then read 12 more pages a day, just in time to finish the book. The loan date of this book…
The loan period for this book was 30 days.
Xiaodong read a book. On the first day, he read 3/5 of the book, and the next day he read 20 pages. At this time, he had read the number of pages in the book.
Xiao Dong read 3/5 of the book on the first day, which was 0.6 times the volume of the book. The next day, he read another 20 pages, which was equivalent to 1/5 of the entire book, which was 0.2 times the volume of the entire book. Therefore, the number of pages Little Dong had read was: The number of pages read = the volume of the book x the number of days read-the total number of pages = 06 × volume of the book × 1 - 02 × volume of the book = 02 × the volume of the book Since the total number of pages in the book did not change, the number of pages that Xiao Dong had read was 0.2 times that of the book.
Xiao Ming read a mini-novel in three days. On the first day, he read more than 6 pages of the book. On the second day, he read half of the book. On the third day, he read 2 pages of the first day.
Xiao Ming read a mini-novel in three days. On the first day, he read more than a quarter of the entire book and six pages. On the second day, he read half of the entire book. On the third day, he read twice as many pages as the first day. According to the description of the title, Xiaoming read 1/4 of the book on the first day, which was 1/4 + 6/100 = 17/100 = 1/5. Therefore, Xiao Ming read about one-fifth of the book on the first day. The next day, Xiao Ming read half of the book. Therefore, Xiao Ming read 1/2 × 1/2 = 1/4 of the book the next day. On the third day, Xiao Ming read twice the number of the first day, which was 1/5 × 2 = 4/15. Therefore, Xiao Ming read about 4/15 of the book on the third day. As Xiao Ming read for a total of 3 days, the total number of pages in the book is: Total pages = Day 1 pages + Day 2 pages + Day 3 pages = 1/5 + 1/4 + 4/15 = 9/10 Therefore, the total number of pages in the novel was nine.
Xiao Jun read a book and read two-thirds of the book in seven days. In the next five days, he read a total of 40 pages and just finished it. How many pages are there in this book?
Suppose the book has x pages: Seven days ago, Xiao Jun read 7 × 2/3 = 14/3 pages, which was 14/3 div7 = 4/9 pages. Xiao Jun read (x + 5) × 4/5 = x + 20/3 pages in the last 5 days. Because Xiao Jun had read a total of 40 pages, there were: 4/9 + 20/3 = x The solution was x = 360/9 + 20/3 = 480/3 pages. Therefore, this book had a total of 480/3 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?
If he read five more pages per day, the total number of pages per day would be 15 * 5/5 = 30 pages. The total number of pages that Xiao Ya needed to read in 20 days was 30 * 20 = 600 pages. If you read 15 pages a day, the total number of pages you need to read is 600 * 15/15 = 600 pages. Therefore, if you read five more pages a day, you can finish the book faster. The answer was: Ya-chan could finish the book in 15 days. She could read five more pages a day, and a total of 30 more pages, so she only needed 20-15=5 days to finish it.
Little Wang read a book. On the first day, he read 12.5% of the whole book. On the second day, he read 136 pages. The ratio of the remaining pages to the number of pages he had read was 3:5...
Let the total number of pages of the book be x, then Xiaowang read 125% on the first day = 0125x 136 pages on the second day, so Xiaowang read a total of 0125x + 136 pages. The ratio of the remaining pages to the number of pages seen is 3:5, so the number of pages left is 0875x- 136, and the number of pages seen is 0875x- 136 + 0125x = 09x. According to the question, the ratio of the remaining pages to the number of pages seen is 3:5, so the equation can be written: 0875x - 136 = 3(09x) Solve the equation: 0125x = 192 x = 144 Therefore, the total number of pages in this book was 144.
A storybook had 600 pages. Ling Ling read 34 pages a day on average. Could he finish the book in 17 days?
No. Ling Ling read an average of 34 pages a day. It would take her 17 days to finish a 600-page story book. But because the storybook had 600 pages, it would take 17 days for Lingling to finish reading half of the storybook, which was 150 pages. Therefore, Ling Ling needed to read 34 pages/2=17 pages every day to finish the 150-page storybook in the 17th day.
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...
Xiaoming reads a storybook, Xiaofang reads a science book. The number of pages in a storybook is 75% of that in a science book. Xiaoming reads 15 pages a day, Xiaofang reads 18 pages a day. If Xiaoming and Xiaofang had a total of 100 pages, then they would read 100 * 15 / 100 = 15 pages a day. The remaining pages were 75% of the pages of the science book, which was 75 * 18 / 100 = 15 pages. Since the number of pages in the story book was 75% of the number of pages in the science book, the remaining pages were 75 / 75 = 1 page. Therefore, Xiaoming and Xiaofang read a total of 15 + 1 = 16 pages a day. They only read one page a day, which meant that they couldn't read the rest of the pages.
Xiao Dong read a book and read 24 pages a day. After 6 days, there were still 3/5 of the book that he had not read. How many pages was this book?
Assuming that the total number of pages in this book is X, then according to the information given in the title, the following equation can be written: Xiao Dong reads 24 pages a day, so he reads a total of $24/times 3 = 72$pages After 6 days, there are still 3/5 of the book left, so there are still $X <br><br><br> By equating the two equations in the system of equations, one could obtain: $$24 \times 3 = \frac{X}{5}$$ Solution: $$X = 72 \times 5 = 360$$ Therefore, the total number of pages in this book was 360.
Little Light read a book. On the first day, he read six pages. After that, he read four more pages every day. On the third day, he read two-fifths of the book and continued to read.
Xiao Hua reads a book on the first day, reads six pages, then reads four more pages every day, and on the third day, he reads two-fifths of the book. According to the question description, Little Light read four more pages every day than the previous day, so the total number of pages per day was the total number of pages on the previous day plus four pages. Therefore, after Little Light read six pages on the first day, the number of pages he read every day was the number of pages from the previous day plus four pages, which was six pages + four pages = ten pages. From the second day onwards, Little Light read four more pages a day than the previous day. Therefore, the number of pages he read every day was the number of pages from the previous day plus four pages, which was 10 pages + 4 pages + 4 pages = 16 pages. By analogy, we can find that when Little Light reads to the n-th day, the number of pages Little Light reads every day is the number of pages from the previous day plus 4 pages, which is n-pages + 4 pages. Therefore, by the third day, Little Light had read 2/5 of the book, which was 32 pages + 4 pages = 36 pages. Therefore, after the third day, Little Light still had 16 pages left to read. The total number of pages in the book was 36, so Little Light needed to read another 16 pages to finish reading.
Wang Xiaoming read 30 pages of a book on the first day
Wang Xiaoming read 30 pages on the first day of reading a book. According to the plot of the novel, the first few pages would usually be read on the first day because curiosity and interest would motivate the reader to start reading as soon as possible. The 30 pages might be the beginning of the story or an important part of the plot, which was why Wang Xiaoming finished reading the 30 pages on the first day. Wang Xiaoming would probably continue to read as the story developed. If this book was a classic novel, Wang Xiaoming would probably continue reading until he finished the story.
