请教一道PREP中的一道DS,请牛牛们指点

Of the 1400 college teachers surveyed, 42 percent said that they considered engaging in research an essential goal.How many of the college teachers surveyed were women.

1>In the survey, 36 percent of the men and 50 percent of the women said that they considered engaging in research an eseential goal.

2>In the survey, 288men said that they considered engaging in research an essential goal.

答案是A,为什么答案不是D呢?

其实1400乘以百分之42就是所有参加调查的老师减去条件2中的288个男老师,剩下的不就是女老师的人数吗?

答案为什么会是A呢?

你知道被调查的没说基本目标的有多少女老师嘛？

1400*58% 这里面男女比例？
