Anne gave birth to a pair of mice. The female gave birth to eight mice, four male and four female. The five females gave birth to eight more mice, four male and four female. If this happens again, how many males would Anne have?

If Anne gave birth to four males and four females, and they all gave birth the same way again, they would have eight males, but if it were to happen again, there would be 12 males and 12 females in total if you don't count all of the females giving birth EACH to four males and four females. Otherwise it would be 40 males, and 40 females.
