What percent of the MIS students enrolled at Wisconsin University are female?

1.5% of female students at Wisconsin University are studying MIS.
2.12% of male students at Wisconsin University are studying MIS.

How is the solution (E)?Is'nt it (A) as the first statement is stating what exactly the ques is asking?what am i missing guys?

[kinjal.nandy]

it just mention about student studying nothing about enrolment...the question ask about the female student enrolled

[JonathanSchneider]

Yes, be careful. This is actually an Overlapping Sets problem.

I suggest you try it again, creating a Double-Set Matrix.

I'll get you started, but you should try it on your own from there:

Set up the rows as "MIS" "NOT MIS" "total."

Set up the columns as "Male" "Female" "total."

If the No. of students studying at W. Univ. means the same as the students enrolled then shouldn't the answer be (C)?

If No. of students at W. University is 'x'
then no. of females studying MIS is 0.05x and male is 0.12x.. Total MIS 0.17x
Thus % of female MIS students at W. University = 5/17%


IF not then do we really need to spend time over forming the double set matrix etc. We could directly jump to (E)

Does GMAT throw such trivial language catch(es) in quant section?

[JonathanSchneider]

Be careful. We are told that 2.12% of the females are enrolled in MIS. This does NOT mean that 2.12% of the overall student body is female. Likewise, that 1.5% of the females are enrolled in MIS does NOT mean that 1.5% of the student body is male.

jigar24, I think you need to set up the Double-Set Matrix only because that will help you to see why the equation you set up is inaccurate.

Alternately, you could jump to "E" because we really have a weighted averages problem. We know the % of the males in MIS, and we know the % of the females in MIS. But we do NOT know the % of the school that is male.
