@Chris'ssistheartist but if it appears in the problem section is a future monthly issue ... I shall show no remorse and put it on my blog along with a solution :P
@Chris'ssistheartist :D .. I bet it'll get selected! :) (not just being nice here) .. it's a wonderful problem and exploiting symmetry is possibly the key
@Chris'ssistheartist I am too stuffed to think straight atm :P (I ate a lot) .. I'll wrestle it once the blood leaves my belly and return to it's rightful place (my head) :P .. so I'm in no hurry :)
@Chris'ssistheartist now you are teasing me ... we both know self-education is the true education .. it's only then we learn when we do it with our own hands and put our mind to it :-)
