@rajeshaaidu : We are talking about the Total number of male students and female students in seperate here.With refence to the post above,the second case assumes the values M = 1 and F = 2.So the Total number of female students are 200 and the male students will still be 100.
So the Males in MIS will be 12 percent of 100 as explained.

a poor worded question.
consider the total no of students be 100
if x be the no of males and 100-x be the no of females.
Statement 1 says that 5% of the female students at wisconsin university are studying MIS. then 0.05(100-x) is the no of females studying MIS. but its not possible to find out the percentage of the female students studying MIS. hence data insufficient

Statement 2 says that 12% of the male students of the univ. are studying MIS. then it means that .12x of the males are studying MIS.. still data is insufficient to find pout the percentage of the female students studying MIS

on combining the two statements,
we get the total no of female students studying MIS as well as the total no of male students studying MIS.
therefore percentage of the female students in the mis class is:-
[0.05(100-x)]/[0.05(100-x)+0.12x]
while solving, x will be cancelled and the percentage can be obtained.

still i am nt happy by this type of questions coz they are poorly worded and rather preparing students for prep for GMAT they are pegging up the students.

How will X be cancelled in the Expression above mate.. ??

How we could take seperatly? It's given total number of student enrolled in the MIS and not the total number of female or male student enrolled in the college. so the assumption taken by getting the answer as E is doubtful.

Let me explain you...

Suppose you consider the total number of students as 100. Statement 1 does not mean that 5% (i.e 5) of them are males. It says 5% of the total male students and not the Total students, which is the reason why the seperate totals are considered here...Hope this clears the air...

I think you are right! Thanks for your explanation and patience. +1 for you.

Wow, this is an awesome question. Some described this question as poorly worded but is not. The wording is right. It is just you need to read the question carefully. Provided information does not mention total population whatsoever but it does mention that the 5% of total female population and 12% of the total male population at WU study MIS. Given these information one can never solve the problem.

Ans : e
Let there be 1000 students in Winconsin university of which M are male and W are female.
 M + W = 1000 - (i)
 Required:
% of female students among the total students enrolled in MIS (i.e.:
(Female enrolled in in MIS “a” ) / (Male enrolled in MIS “b” + Female enrolled in MIS “a”)

Case 1:
5% women in Wisconsin studying MIS (a) = 5% of W = .05W
We do not have value of “a” or “b”.
Not sufficient

Case 2:
12% of men in Wisconsin studying MIS (b) = 12% of M = .12M
We do not have value of “a” or “b”.
Not sufficient.

Case 3: Combining case 1 and case 2, we have value of men and women studying MIS when the total number of students is 1000.
Students studying MIS : .05W + .12 M
But we do not value of W and M.

Not sufficient

E (Insufficient information)

Lets make a table

Female Male
MIS Course 5% of total female M=12% of total Male
Other Courses 95% 88%
Total in Wiscosin Univ = 200 100% 100%

For 1st statement, we can look at Female column, everything is in percentage.. we are not given a whole number a ratio with respect to Female studentsa ratio with respect to Female students such as total number of Female students or a ratio with respect to male students... Not sufficient

For 2nd statement, we can look at Male column, everything is in percentage.. we are not given a whole number such as total number of students and a ratio with respect to Female students... Not sufficient

Combining Both 1 & 2 statements, again we don't have a whole number such as total number of students or total number of girl students.

It has to be answer c!

You are not understanding the question...

the question asks what percent of MIS students... so the total population should be MIS students at Winsconsin University...

Therefore, we know that 5/17 % of the MIS students at Winsconsin University are female.

Anwer is c!

If 100 is total no. of Students in W Univesity,
a) then there are 5 nos. of students who are women and MIS student and
b) there are 12 nos. of Students who are men

So 5 / (5+17) is ratio of women to total students who are pursuing MIS in W University. Hence we need both the statements to answer the question.

You need to know the total number of students enrolled in the MIS program, which is not given... you're given the total of females at the university studying MIS, agree?

So neither pieces of information are sufficient to answer the question

1. We don't know total number of students at WU and total number of MIS students. Not sufficient. Option A and D out.
2. We don't know total number of students at WU and total number of MIS students. Not sufficient. Option B out.

Together: We do not know the proportion of male and female students at WU. Not sufficient. Option C out.
