There are 35 students in a college lecture theater. What is the ratio of male students to female students in the lecture theater?
(1) There are 10 male students in the lecture theater.
(2) If the number of male students in the lecture theater was doubled, the ratio of male students to female students in the lecture theater would be 4 to 5.
(1) There are 10 male students in the lecture theater.
(2) If the number of male students in the lecture theater was doubled, the ratio of male students to female students in the lecture theater would be 4 to 5.
This might sound silly. Is it same to assume that GMAT only considers Male and Female genders?
For example, the DS question below
Is it safe to assume (1) is sufficient?

Yes Gmat assumes only two genders.
Moreover I think the answer should be D as Even second statement is enough to find the ratio.

(1) There are 10 male students in the lecture theater.
This implies that there are 24 females, thus the ratio is 10/25. Sufficient.
(2) If the number of male students in the lecture theater was doubled, the ratio of male students to female students in the lecture theater would be 4 to 5.
The statement tells us that 2m/f = 4/5. Together with m + f = 35 we have two distinct linear equations, so we can solve for m and f and get the ratio. Sufficient.
Answer: D.
P.S. Yes, you can consider only two genders.
