Ok this is not a logic question so lets try it out...\r
\n" ); document.write( "\n" ); document.write( "125x72=9000 and 72 tons
\n" ); document.write( "75x120=9000 and 120 tons\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "That is the basic, we're not down to the answer.. yet\r
\n" ); document.write( "\n" ); document.write( "we need a little educated guess, so lets try 16 tons of $125 and 84 tons of $75.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "125x16=2000
\n" ); document.write( "75x84=6300\r
\n" ); document.write( "\n" ); document.write( "2000+6300=8300\r
\n" ); document.write( "\n" ); document.write( "Pretty close.. the difference between 125 and 75 is 50 and we need 700 more so:\r
\n" ); document.write( "\n" ); document.write( "700/50=14 \r
\n" ); document.write( "\n" ); document.write( "That means we need to turn 14 tons of $75 into $125 tons.\r
\n" ); document.write( "\n" ); document.write( "So that means we should have 30 tons of $125 and 70 tons of of $75\r
\n" ); document.write( "\n" ); document.write( "125x30=3750
\n" ); document.write( "75x70=5250\r
\n" ); document.write( "\n" ); document.write( "3750+5250=9000
\n" ); document.write( "30+70=100\r
\n" ); document.write( "\n" ); document.write( "Oh we now found the answer.. there were 30 tons worth $125 ans 70 tons worth $75. \n" ); document.write( "

\n" );
