C should be the answer.

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.

The answer is C

I think your answer is not correct.

Statement 1 says: 5% of Female students study MIS, not 5% of TOTAL students are Female & study MIS. For instance, there are 100 students, 40 are female, and 5% of 40 is 2 students.

Statement 2: 12% of Male students study MIS, not 12% of TOTAL students are MALE & study MIS.

E is correct. The question is tricky because we only know

5% of F, and

12% of M, but we don't know the ratio between F and M.

For example:

1000 Students, 400F, 600M. So 5% of 400 = 20, 12% of 600 = 72 --> % F & MIS = 20/(20 + 72) = 21.7%

1000 students, 500F, 500M. So 5% of 500 = 25, 12% of 500 = 60 --> % F & MIS = 25/(25 + 60) = 29.4%

Hope it's clear.
