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.
Little Ming read a book. After seven days, there was still a quarter of the book left. In the next five days, he read a total of 120 pages, just enough to finish it. How much did Little Ming read on average every day?
假设这本书有 $n$ 页小明读了 $x$ 天。 根据题意小明读了 $x$ 天后这本书还剩下 $1/4$ 于全书的比例即 $\frac{1}{4}n = \frac{1}{4}x(n-x)$。 接下来小明读了 $x+7$ 天后这本书还剩下 $1/4$ 于全书的比例即 $\frac{1}{4}x(n-x) + \frac{1}{4}x^2 + \frac{1}{4}x^3 + \frac{1}{4}x^4 + \frac{1}{4}x^5 = \frac{1}{4}n$。 化简得到 $x^5 - 4x^4 + 3x^3 - 12x^2 + 25x - 4n = 0$。 这是一个由 $5$ 个方程组成的线性方程组可以通过特征值或特征方程的方法求解。 特征值计算如下: 设 $a_1 = 1$$a_2 = -2$$a_3 = -3$$a_4 = -5$$a_5 = -1$则特征方程为 $a_1^5 + a_2^4 + a_3^3 + a_4^2 + a_5^1 = 0$。 解得 $a_1 = 1$$a_2 = -2$$a_3 = -3$$a_4 = -5$$a_5 = -1$因此 $x = (-2 + 3i)(-3 + 5i)(-5 + 1i) = 3$即小明读了 $3$ 天。 因此小明读这本书平均每天读 $3$ 页。
Xiao Ming read a book. He read 72 pages in the first 4 days and 29 pages a day for the next 6 days. How many pages did he read on average every 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.

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.
