Re: math problem
Just label the coins randomly 1,2,3,...,15,16 . Treat it like a tournament with 8 coins on one side of the bracket and 8 coins on the other . As usually the pairings are done randomly according to their number .
ie , one side is (1,2),(3,4),(5,6),(7,8) . The other side can be paired off similarly. So there are 15 possible matches in total to determine the heaviest i.e,8+4+2+1=15 .
