Xiao Wang reads a 500-page novel. He reads 1 page more every day than the day before. He pretends to finish reading the book in 15 days. How much did he read on the last day?
Xiao Wang reads a 500-page novel. He reads 1 page more every day than the day before for 15 days. How many pages did he read on the last day? Reading an extra page every day meant that Little Wang could read 500 pages + 1 page = 501 pages every day. He read for a total of 15 days, so the total number of pages Little Wang read was 500 pages x 15 days = 7500 pages. The number of pages he read on the last day was 7500 - 501 = 7099.
A 600-page book. Every day, he would read one more page than the day before, and he would finish it in 16 days. How many pages did you read on the last day?
If the number of pages of the book is x, then the first day is x/page, the second day is (x/page)/2, and so on, the 15th day is (x/page)/16. Because I read one more page every day than the day before, the number of pages I read in 16 days can be expressed as: (x/page)/16 + (x/page)/17 + (x/page)/18 + + (x/page)/15 This is a geometric sequence and the sum is x/page. Therefore, the common ratio of this exponential series is 16, and the first term is x/page. By replacing x/page with the first term of this exponential sequence, we get: (x/page)/16 + (x/page)/17 + (x/page)/18 + + (x/page)/15 = x/page To simplify it: (16x/15)/16 = x Solution: x = 600 Therefore, the book had 600 pages.
Xiao Ming reads a book. If he reads 15 pages a day, he will finish it in 24 days. If he reads 20 pages a day, how many days will he finish it?
If Xiao Ming reads 15 pages a day, the total number of pages he needs is: 15 pages/day x 24 days = 360 pages Therefore, Xiao Ming needed to read 360 pages to finish it in 24 days. The number of days required to read 20 pages a day is: 20 pages/day x days = 20 days Therefore, Xiao Ming needed to read for 20 days to finish the book.
If Little Ming reads a book, if he reads 15 pages a day, he will finish it in 24 days. If he reads 20 pages a day, how many days will he finish it?
If Xiao Ming reads a book every day for 15 pages and 24 days, then the book has a total of 15 * 24 = 360 pages. If I read 20 pages a day, how many days can I finish it? Assuming that the book has x pages, the total number of pages that Xiaoming needs to read is 20 * x days. Because Xiao Ming needed to read 360 pages, there were: 20 * x = 360 Solve this equation: x = 180 Therefore, Xiao Ming needed to read 180 pages to finish the book. If he read 20 pages a day, he would need 180 * 20 days = 3720 days to finish the book.
If Xiaoming reads a novel and reads 35 pages a day, he will finish the book one day later than the stipulated date. If he reads 40 pages a day, he will read 5 pages less on the last day…
Xiao Ming reads a novel. If he reads 35 pages a day, he will finish the whole book one day later than the stipulated date. If he reads 40 pages a day, he will read 5 pages less on the last day. We can set the total number of pages of the novel as x and the specified date as d, then the total number of pages that Xiaoming needs to read is x/35 + x/40 - 1. According to the question, Xiaoming needs to read d books, so there are: x/35 + x/40 - 1 = d Transferring the terms of the equation gave: x/100 = d Therefore, Xiao Ming needed to read 100 pages a day to finish the novel by the stipulated date. If you read 35 pages a day, you would need an extra two days to finish the novel. If you read 40 pages a day, you would need an extra three days to finish the novel. After considering all, Xiaoming needed to read 37 pages a day to finish the novel according to the stipulated date. On the last day, he had to read 5 pages less.
Xiao Lin spent five days to finish reading a 70-page book. On average, how much of the book did he read every day? How much of this book did he read in three days?
Kobayashi spent five days to finish reading a 70-page book. On average, he would read the book every day (page count/days)×(days/2)= (70/5)×(5/2)=14 pages/day. 3 days to read this book (page count/day count)×(day count/2)= (70/3)×(3/2)=20 pages/day.
In a book, Xiaoming reads page a every day on average for 7 days. How many pages does he start reading on the eighth day?
In a book, Xiao Ming read page A for an average of seven days a day, so he read page 7A in total. Therefore, the number of pages to read on the eighth day should be: 8 days × a pages/day = 7a pages Adding the first 7 pages and the last 1 page gives: 8 + 7 = 15 days Because Xiao Ming had already read page 7a on the seventh day, the remaining pages should be: 15 days-page 7a = page 8a Therefore, Xiao Ming should start reading page 8a on the eighth day.
If Xiao Qiang reads a literary masterpiece, if he reads 20 pages a day, he can finish it in 18 days. If he reads 5 pages less a day, how many days can he finish it?
If you read 20 pages a day, you can read one literary masterpiece in 18 days, which is an average of 217 books per month. If you read five pages less a day, then it would take 10 days to read 15 pages a day, and it would take another 7 days to read 20 pages in 18 days.
A 130-page novel, Xiaoming reads an average of four pages a day. Can he finish it in 28 days?
No. If Xiao Ming reads four pages of a novel every day, then it would take him 28 days to finish a 130-page novel because reading four pages a day would require a total of 130 pages, 4 = 35 pages. However, because the length of the novel was fixed, Xiaoming could not finish the book in 28 days, so the answer was no.
Xiao Hong reads a 254-page storybook. He reads 24 pages a day. He is expected to start reading from August 22 to September 1. He can finish reading this book before school starts.
Xiao Hong reads a 254-page storybook. He reads 24 pages a day. It is estimated that he will start reading from August 22nd to September 1st. The probability of him finishing this book before school starts is: 254 pages/24 pages/day = 10 days Since Little Red needed 10 days to finish reading the 254-page storybook, he needed to finish reading from the first day to the tenth day before August 22nd, which was 7 days and 12 hours. The remaining reading time is 254 pages/24 pages/day = 10 days Therefore, Little Red could finish reading more than 95% of the book before August 22nd, which meant that it would take 95 days. However, there were 29 days in February in leap years, so whether Little Red could finish reading before August 22 depended on whether it was a leap year or not. If it wasn't a leap year, he would need to finish reading from the first day to the tenth day after August 21st, which was 7 days and 12 hours, and then calculate if he could finish reading before August 22nd.
Ming has a 170-page book. He read 80 pages in the first 4 days. If he wants to finish reading it in a week, how much should he read every day from the fifth day?
Ming has a 170-page book. He read 80 pages in the first 4 days. If he wants to finish it in a week, how many pages will he read every day from the 5th day onwards? From the 5th day onwards, read x pages every day, where x represents the number of pages that the nickname reads every day from the 5th day onwards. Reading 170 pages a day required 170 pages divided by 5 days = 34 pages per day. Therefore, from the fifth day onwards, Ming Xiao needed to read 34 pages a day.
