2 WEIGHING SOLUTION:
\n" ); document.write( "WEIGH 3 ON EACH SCALE.
\n" ); document.write( "IF THESE 6 BALANCE EQUALLY THEN WEIGHT THE REMAINING 2.
\n" ); document.write( "THE HEAVIER ONE WILL SURFACE.
\n" ); document.write( "ASSUMING TTHE ORIGINAL WEIGHING SHOWS ONE SET OF 3 ARE HEAVIER.
\n" ); document.write( "CHOSE TWO OF THE HEAVIER GROUP & WEIGH THEM.
\n" ); document.write( "IF ONE IS HEAVIER SOLVED.
\n" ); document.write( "IF THE 2 YOU SELECTED ARE EQUAL THEN ONE NOT WEIGHED IS THE HEAVY 1.
\n" ); document.write( "---------------------------------------------
\n" ); document.write( "3 WEIGHING SOLUTION:
\n" ); document.write( "WEIGH 4 & 4.
\n" ); document.write( "DIVIDE THE HEAVIEST 4, 2 & 2 & WEIGH THEM.
\n" ); document.write( "DIVIDE THE HEAVIEST 2, 1 & 1 & WEIGH THEM.
\n" ); document.write( "THE HEAVIEST WILL SURFACE. \n" ); document.write( "
