My highly intelligent forumites, pls help me and solve this question that i was asked when i wrote beztest.
1) 8 gems, 1 is fake. Use the balance twice to identify which weighs twice as the originals.
Well since one of the Gem is Fake, & weights as double;what he'll do is that he'll need to place the Gem one @ time on the 2 sides of the weighing Machine & it must Balance so immediately one side is heavier than the other this means the Last Gem stone he placed on the side is the Fake then he'll need to Confirm the 2nd time by Placing 2 on side & Balancing it with the one he has gotten earlier.
will revert on the 3rd Soon.
Best of luck Mate!
