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.
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.
Please +1 KUDO if my post helps. Thank you.
