In the first three days, he read 43 pages. In the next four days, he read 12 pages a day. How many pages did Le read on average?

Xiao Ming read a book for the first 4 days and read 15 pages, then read 6 pages every day for 5 days. We can use the following formula to calculate the average number of pages seen per day: Average number of pages read per day = total number of pages/days Substituting the total number of pages and the number of days into the formula, we get: Average number of pages read per day = 15 pages/4 days = 3 pages/day Therefore, Xiao Ming read an average of three pages a day.

If Xiaoming reads 72 pages in the first 4 days, then Xiaoming's total page count in the first 4 days is 72 pages. Reading 29 pages every day for the next 6 days would mean that the total number of pages for the next 6 days would be 29 pages x 6 days = 171 pages. Therefore, Little Ming's total page count in the last six days was 171 pages. Little Ming read 171 pages per day for the next 6 days, 6 days = 27 pages. Therefore, Xiao Ming read an average of 27 pages a day.

Wang Qiang read a book for the first four days, eight pages a day, and then a total of 17 pages for the next three days. We can split this situation into two parts for analysis: Reading eight pages a day for the first four days meant that Wang Qiang had already read $4/times 8 = 32$pages in the first four days. Reading a total of 17 pages in the last 3 days meant that Wang Qiang had read another $3/17 = 54$page in the last 3 days. Therefore, Wang Qiang read a total of $32+54=86$pages. Next, we need to calculate how many pages he reads on average every day. Did he read all the books in the first four days and the last three days together? If that was the case, then the average number of pages he read every day was $86/4+17/3=265+5=315$pages. If not, then the average number of pages he read every day was $86/4-17/3=26-5=21$pages. Therefore, Wang Qiang read an average of 21 pages a day.

Suppose the book has a total of x pages, and Chen Ming has read a total of y pages in these seven days: - Chen Ming read 11*3=33 pages in the first three days - In the next three days, Chen Ming read a total of 18*3=54 pages - In seven days, Chen Ming read a total of y*7=497 pages Therefore, Chen Ming read an average of 497/7=74 pages a day in the past seven days.

Assuming that the total number of pages Xiao Dong read every day was constant, then the average number of pages he read every day could be calculated by calculating the total number of pages in the first 4 days and the last 3 days. The total number of pages read in the first four days was 68, so Xiao Dong had read a total of 68 pages in these four days. The total number of pages he read in the next three days was 72 pages, so Xiao Dong read a total of 72 pages in these three days. Therefore, Xiao Dong had read a total of 68 + 72 + 10 + 2 = 190 pages in these 8 days. Divide the total number of pages by the total number of pages you read every day to get the answer to how many pages Xiao Dong reads on average every day: 190/8 = 225 pages The answer was 225 pages because Xiao Dong read an average of 225 pages a day.

Xiaoming read a book for the first four days, on average, he read eight pages a day. In the first four days, he read a total of 8 × 4 = 32 pages. In the next two days, he read a total of 48 pages, which means that in the remaining time, Xiaoming read an average of 48/7 = 8 pages per day. Therefore, Xiao Ming spent the rest of his time reading an average of 8 - 8 = 0 pages a day. In other words, Xiao Ming had already finished reading the book, so he read an average of 0 pages a day.

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.

Xiao Dong read 68 pages in the first 4 days and 72 pages in the next 3 days, so the total number of pages in the book was 68+72+4*10=190 pages. How many pages does Xiao Dong read on average every day? How many days did Xiao Dong watch it? (Note: You need to add the first 4 days and the last 3 days to get the total number of days.) Xiao Dong reads an average number of pages per day = total pages/total days =190 pages/14 days =14 pages/day Therefore, Xiao Dong read an average of 14 pages a day. Therefore, he chose option A.

Xiao Dong read a storybook for a total of 68 pages in the first 4 days and 72 pages in the next 3 days, so the total number of pages read was:68+72+4*3=191 pages. How many pages does Xiao Dong read on average every day? It took Xiao Dong seven days to finish reading the book, so the average number of pages Xiao Dong read every day was 191/7=25 pages. Therefore, the correct calculation was page 25. The statement on page 20 of Item A was wrong. Page 17 of Item B and page 18 of Item C were all correct. Item D, page 26, is incorrect.
