Thabo owns exactly 140 books, and each book is either paperback fiction, paperback nonfiction, or hardcover nonfiction. If he owns 20 more paperback nonfiction books than hardcover nonfiction books, and twice as many paperback fiction books as paperback nonfiction books, how many hardcover nonfiction books does Thabo own?
请问大家标黄的那句话的意思是paperback fiction的数量是 paperback nonfiction 的两倍 还是 paperback nonfiction 是 paperback fiction的两倍？
答案是： paperback fiction的数量是 paperback nonfiction 的两倍 ，但是我做题的时候觉得是paperback nonfiction 是 paperback fiction的两倍，现在看着还是有点想不通。
