Chandra 和 Bob 各有一本书，他们决定用“团队阅读”来节省时间。按照这种方法，Chandra 从第 页读到某一页，Bob 从下一页读到第 页，读完整本书。读完后他们会互相讲述自己读的部分。为了让 Chandra 和 Bob 阅读时间相同，Chandra 应该读到最后哪一页？
Chandra and Bob, who each have a copy of the book, decide that they can save time by “team reading” the novel. In this scheme, Chandra will read from page to a certain page and Bob will read from the next page through page finishing the book. When they are through they will tell each other about the part they read. What is the last page that Chandra should read so that she and Bob spend the same amount of time reading the novel?
小提示：
设 为 Chandra 阅读的页数。
Let be the number of pages Chandra reads.
大提示：
令 Chandra 阅读 页的时间等于 Bob 阅读剩余页数的时间。
Set Chandra’s time for pages equal to Bob’s time for the remaining pages.
解答：
设 Chandra 阅读 页，那么 Bob 阅读 页。
为了让阅读时间相同，
所以正确答案是 C。
Let be the number of pages that Chandra will read. Then Bob will read pages.
For them to read for the same amount of time,
Thus, C is the correct answer.
