Interesting! Is this the exact wording? Probably something to do with lateral thinking. It could be something over simple like "By adding 30".

If you take half of 20, you get 10, then by adding ten you have 20. The question asks how you get 50. Well, by adding 30.

Could that be it?

the test question actually said, "Take half of 20 then add 10." I know, it just doesn't make sense...the test said that the answer should be 50. Thanks for your ideas, scramble!
