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.
Xiao Hong read a novel. On the first day, she read 9 pages more than 1/12 of the total number of pages. On the second day, she read 7 pages less than 1/8 of the total number of pages, leaving 93 pages.
The total number of pages Little Red read on the first day was (12+9)/(12×1+9)= 13 pages. The total number of pages Xiao Hong read the next day was (13-7)/(8×1+7)= 9 pages. The number of pages Little Red read the next day was 7 pages less than the first day, and the remaining pages were 9 pages more than the first day. Therefore, the total number of pages she read the next day was 9/7 times that of the first day, which meant that she read 18 pages the next day. According to the total number of pages read on the first day and the total number of pages read on the second day, the total number of pages of the novel could be calculated as:13+9+18=40 pages. Therefore, the novel that Little Red was reading was the 40-Page Fictions.
If I read 30 pages a day, I can finish it 10 days earlier. If I read 15 pages a day, I can finish it 10 days later
The time spent reading a book depends on the number of pages you read each day. Reading 30 pages a day is 10 days slower than reading 15 pages a day. So if we were to read 30 pages a day, we would need to spend an extra 10 days on top of the original 10 days to finish the book. On the contrary, if we read 15 pages a day, we would need to spend an extra five days on top of the original 10 days to finish the book. So we can finish the book ten days earlier or ten days later, depending on the number of pages we choose to read and our reading speed.
Little Red read a novel. On the first day, she read 1/12 of the total number of pages, which was 19 pages more. On the second day, she read 17 pages less than 1/8 of the total number of pages, leaving 93 pages left. This...
Xiao Hong read a novel on the first day, and she read 1/12 of the total number of pages, which was 19 pages more. On the second day, she read 17 pages less than 1/8 of the total number of pages, leaving 93 pages. On the first day, he read 1/12 of the total page count, which was 19 pages more. On the second day, he read (1-1/12)×19 = 11/12 pages. Since there were 93 pages left, he read 93/11/12 = 108 pages. The next day, if you read 17 pages less than 1/8 of the total number of pages, then you read (1-1/8)×17 = 7/8 pages the next day. Since there were 93 pages left, you read 93/7/8 = 160 pages the next day. Therefore, the total number of pages Little Red had read was 160+93=253.

Xiao Hong read a novel on the first day, and she read 1/12 of the total number of pages, which was 19 pages more. On the second day, she read 17 pages less than 1/8 of the total number of pages, leaving 93 pages. If the total number of pages in this novel is X, then the number of pages that Little Red reads on the first day is X/12+19, the number of pages that she reads on the second day is X/8-17, and the remaining number of pages is X-93. According to the meaning of the question, the following equation can be listed: The number of pages Xiaohong read on the first day + the number of pages Xiaohong read on the second day = X/12+19+X/8-17 = X To simplify it: X = 962 Therefore, the total number of pages in this novel was 962. On the first day, Little Red read 962/12+19=86 pages. On the second day, she read 962/8-17=105 pages. The remaining pages were 962-93=871 pages. Little Red had read a total of 962+871=1733 pages, which was 93 pages less than the actual total number of pages. Therefore, Little Red had actually read 1733-93=1640 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.
He had read 12 pages on the first day, 6 more pages on the next day, and 48 pages on the last day. How many days had he read?
After reading 12 pages on the first day, he read 6 more pages every day than the previous day. On the last day, he read 48 pages. How many days did he read in total? He had read $12+12 + 12 + 12 + 12 +12+6+48$in total. Reading 6 more pages a day than the day before, so obviously in the first week, I read $12+12 + 12 + 12 + 12 +12+6+12=55$days. In the second week, he read $12+12 + 12 + 12 + 12 +12+6+12+12=63$days. By analogy, we can know that the total amount of reading before the end of the book is $55+63+70+73+80+86+98+48=695$days. Therefore, he read for a total of seven days.
A book has a total of 150 pages, and Xiao Ming has already read 54 pages. The remaining pages are 8 pages a day, and it will take him a few days to finish them.
Xiao Ming had already read 54 pages and was reading 8 pages a day. Therefore, he still needed 8 × 7 = 56 days to finish reading the remaining pages.
If Xiao Ming read 35 pages a day, he would finish the book one day later than the stipulated date. If he read 40 pages a day, he would have to read 5 pages less on the last day.
Xiaoming reads a novel. If he 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. Based on this information, we can formulate the following equation: Let the total number of pages in the novel be x Xiaoming reads x/35 days, that is, he reads x/35 pages every day. Because Xiao Ming needed to finish reading the entire book, he needed to meet the following two conditions: Xiaoming finished reading the novel before the stipulated date 2 Xiao Ming reads 35 pages a day, so the total number of pages read is 35x/12 days Therefore, we can write the following equation: x/35 = (x/12) - 1 Solve the equation: x = 35x/12 + 1 = 40 Therefore, Xiao Ming needed to read 40 pages to finish the novel. He needed to read 40/35=8/17 days before the specified date. However, because reading 40 pages a day is slower than reading 35 pages, the actual time he needs will be longer than 8/17 days, that is, he will need 16/17 days to finish reading the novel.
