I'm rubbish at maths, but where did the hand written bit come from, yes the figures shown are wrong, who wrote them?.

Been googling, as it's a long time since I did that. Yes I agree at 150 ish, I do like a good brain teaser though.

Sorry, I made y=23, x=134. Doesn't fit the drawing unless it's badly drawn... It's a long time since I was 15 though 🙂
