I had to do this past paper from the uk maths challenge and could do all of them bar 23 and 25. Any help or starting points would be great :D
numbers 23 and 25

23. I did some pythagorus, and found things in terms of PR, and ended up going in circles a few times, but fear i have missed a key concept. can someone tell me where to begin?
25. not sure where to begin. I 'could' in theory do in the long and very slow way of trial and error, but in a exam an hour long there must be a way to do it... just advice on where to begin would be nice :D
thnx
