In the army kitchen there are four pots for every three pans for every 21 glasses. All together there are 476 of these items. How many pans are there?
\n" ); document.write( "a=pots; b=pans; c=glasses; So, 4a + 3b + 21c = 476
\n" ); document.write( "Now what?
\n" ); document.write( "----------------
\n" ); document.write( "So, 4a + 3b + 21c = 476
\n" ); document.write( "The trick is, a, b & c are integers. You can't have 2/3 of a pot or pan.
\n" ); document.write( "-----------
\n" ); document.write( "4 + 3 + 21 = 28
\n" ); document.write( "476/28 = 17
\n" ); document.write( "-----
\n" ); document.write( "pots = 4*17 = 68
\n" ); document.write( "pans = 3*17 = 51
\n" ); document.write( "glasses = 21*17 = 357
\n" ); document.write( "
\n" ); document.write( "
\n" );
