第一次做套题测验，打击的不行。看答案的时候感觉这题有点疑问，麻烦哪位大侠帮忙看一下，小女子在线等！谢谢先！

In 2003 Acme Computer’s price for each of its computers was five times the price for each of its printers. What was the ratio of its gross revenue from computers to its gross revenue from printers in 2003?

(1) In the first half of 2003, Acme sold computers and printers in a ratio of 3:2; in the second half of 2003, Acme sold computers and printers in the ratio of 2:1.

(2) Acme’s 2003 price for each of its computers was $1000.
      Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
      Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
      Both statements TOGETHER are sufficient, but NEITHER one ALONE is sufficient.
      EACH statement ALONE is sufficient.
      Statements (1) and (2) TOGETHER are NOT sufficient.

正确答案选了E，不知道是我理解错误还是什么呢，我怎么觉得应该选C呢？
