I got answer as E .
I think E is the answer it the second statement is
(2) There are half as many men at College X as there are students who live on-campus
the answer will be B if the 2 statement is
(2) There are half as many men at College X as there are students who live off - campus
Hi Dookie ,
In your equation you took 200 , 200 - live off campus but (2) says live on campus , we have no data regarding live on campus.
By writing T-200, he is looking at the on campus people, because the T is the total, and the 200 is the off campus people, leaving T-200 on campus.
I did it a bit differently. I don't like minuses, so much, so I said x was the number of people on campus, and got:
.5x + 400 = x + 200
The left side is the number of students when adding up men and women, and the right side is the number of students when adding up on campus and off campus.
Since x can be solved, B is enough.
