You can put this solution on YOUR website! 2 WEIGHING SOLUTION:
WEIGH 3 ON EACH SCALE.
IF THESE 6 BALANCE EQUALLY THEN WEIGHT THE REMAINING 2.
THE HEAVIER ONE WILL SURFACE.
ASSUMING TTHE ORIGINAL WEIGHING SHOWS ONE SET OF 3 ARE HEAVIER.
CHOSE TWO OF THE HEAVIER GROUP & WEIGH THEM.
IF ONE IS HEAVIER SOLVED.
IF THE 2 YOU SELECTED ARE EQUAL THEN ONE NOT WEIGHED IS THE HEAVY 1.
---------------------------------------------
3 WEIGHING SOLUTION:
WEIGH 4 & 4.
DIVIDE THE HEAVIEST 4, 2 & 2 & WEIGH THEM.
DIVIDE THE HEAVIEST 2, 1 & 1 & WEIGH THEM.
THE HEAVIEST WILL SURFACE.
