There are many benefits to timing your practice, including:

(1) 2/5 of the male students at College C are business majors --> 2/5*M=Male Business Majors. Not sufficient.

(2) 200 of the female students at College C are business majors --> Female Business Majors=200. Not sufficient.

(1)+(2) {Business Majors}={Male Business Majors}+{Female Business Majors} --> 2/5(F+M)=2/5*M+200 --> 2/5*F=200 --> F=500. Sufficient.

Answer: C.

Based on what you put for (2), (2/5)(Females) = 200, therefore Females = (5/2)(200) = 500. Why bother tangling it with the males? We already know from the question that (2/5)(Males + Females) = business majors and statement 1 is just a repeat of what is given.

There was a typo.

From (2): 200 of the female students at College C are business majors --> Female Business Majors=200. Not (2/5)(Females) = 200. _________________

I hope you will be patient with me since it's been a long morning, but here is my reasoning, even after sifting through the various related threads:

We are given that 2/5 of the students are business majors so (2/5)(Males+Females) = Business majors. Expanded, we have Business majors = (2/5)(Males)+(2/5)(Females) = Business majors. Therefore 2/5 males are business majors and 2/5 females are business majors.

Statement 1 just repeats that (2/5)(Males) are business majors

Statement 2 says that 200 females are business majors. We can equate that (2/5)(Females) = 200 from the expanded information provided and have the final form be Females = (5/2)(200) = 500.

For the life of me I cannot see how statement 2 is insufficient unless I am confused about how the information they gave us is constructed as stated.

The red part is not correct. 2/5 (40%) of the students are business majors does not mean that 40% of males and 40% of females are business majors.

For example: say there are 300 males and 200 females (total of 500 students), then there will be 2/5*500=200 business majors. So, it could be that 100% of females and 0% of males are business majors.

I can see how that situation will make what I said incorrect, but then I do not know how I would setup a question like this in the future. I was under the impression that students = males + females. Therefore if 2/5 students are business majors, then 2/5 (males + females) are business majors. What rule did I violate to cause me to tunnel vision into thinking that the aforementioned equation could be expanded into (2/5)(males) + (2/5)(females)?

Again: 2/5(Female+Male)=Business Majors CAN be expanded as 2/5*F+2/5*M=Business Majors, but it does not mean that 2/5 of males and 2/5 of females are business majors. _________________
