时间Thu Jul 24 01:15:43 2008
问橘本计量~ 题目英文有不懂地方~ 11版 3.1-6, 页48~
6.
A marketing firm determined that, of 200 households surveyed, 80 used neither
Brand A nor Brand B soap, 60 used only Brand A soap, and for every houshold
^^^^^
请问for在这此是代表以used both brands of soap 为基准的意思嘛??太微妙了~
因为解答设both 有A有B为X ,只有B为3X
that used both brands of soap, 3 used only Brand B soap. How many of the 200
households surveyed used both brands of soap?
(A)15 (B)20 (C)30 (D)40 (E)45 答案A
这题会算..只是对计量的英文有点不适应:P 请大家回应一下 我这样解释是正确的嘛:P
问简单的不要笑我= =
