Solve this kind of problem by considering a "worst case" scenario.

If you want to get three brown candies, the worst that can happen is that you get all of the other candies before you get any brown ones.

So the first 45 candies are the 20 red and 25 green; then you need to pick three more candies to get three brown.

20+25+3 = 48.
