Don't really know how to do this question help?

Suppose Afenia can produce 50 computers or 20 bottles of brandy (or any combination in between). Booland can produce 100 computers or 100 bottles of brandy (or any combination in between). With no trade, each chooses production and consumption in the middle of its PPF (25 computers and 10 bottles for Afenia; 50 computers and 50 bottles for Booland). If they decide to trade in such a way as to keep their consumption of brandy unchanged, what is the largest (combined for the two countries) number of computers they can consume?
