    if i'd thought about it before posting the first one that occurred to me then i would have realised that any 2 numbers adding up to 9 could be a and b so
    a =1 b=8,
    a=2, b=7
    etc

    Indeed, there was me thinking it was badly written algebra. It's not maths, it's a silly wee puzzle.

    Yeah, I got this straight away. 8 possible answers. (not counting Tesco's)

    100 - 81.5 = 18.5
    100 - 72.5 = 27.5
    100 - 63.5 = 36.5
    100 - 54.5 = 45.5
    100 - 45.5 = 54.5
    100 - 36.5 = 63.5
    100 - 27.5 = 72.5
    100 - 18.5 = 81.5
