You could imagine ...I'm with Josh on this one. You could imagine the weight difference being slight enough that you couldn't measure it by hand. Or perhaps the balls themselves are cannon balls, and so you're not capable of holding them both up.<br /><br />The answer: as Charli already said: Put 2 of the balls aside. Weigh 3 of the remaining balls against the other 3 remaining. If they are the same then weigh the 2 balls that you put aside to find out which of them is heavier. If, instead, one of the sets of 3 balls was heavier, put one of the balls from the heavier set aside. Weigh the remaining two balls from the set to find out which one is heavier. If they are equal then you know it is the 1 ball that you put aside.Anonymoushttps://www.blogger.com/profile/18153935609499338685noreply@blogger.comtag:blogger.com,1999:blog-15628310.post-61179023152760497002009-12-01T22:51:07.037-05:002009-12-01T22:51:07.037-05:00If you were allowed to use your hands, there woul...If you were allowed to use your hands, there would be no need for the scale in the first place!<br /><br />I believe Charli has the correct solution, but I could be wrong...Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-15628310.post-71556006648827560782009-12-01T11:11:28.363-05:002009-12-01T11:11:28.363-05:00Weigh 1234 vs 5678.
