You have 4 weights weighing 2,3,5 and 7 pounds. The problem is none of them are marked. What is the fewest number of weighings you need using a balance scale figure out which weights are which?
(In reply to
re(3): done in 3 weighings.... I think =P by Brian Smith)
the question asks for the fewest number of weighings... if you get the initial weighing then it's 3...if not... then 4 or 5 weighings is necessary... but the fewest number of weighings would be 3 =D
