Riddle #1

[SigmaSD]

I have this riddle for all of you. If you get it right, I'll give you some good RP. If you get it wrong, it doesn't matter, I won't bad rep you. Just make sure to read the question carefully. The bold text are hints. My only real hint is that this isn't a math problem.

Aliens:

An astronaut goes to an alien planet. When he's there, he notices that 100 aliens are male, 200 aliens are female, and 150 aliens are both sex. If the aliens reproduce every hour, how many aliens are on this planet after six hours?
