Hi Taeo - Granny Jenny here. Some of those are pretty hard maths questions. I managed to work out the 50% and 25% off with pen and paper, but couldn't do the 33.3% one at all. So I gave it to Grandad Owen. He has a maths degree. His first try at it was wrong, so then he "cheated" and used his calculator to get it right.
