A trader has 100 Kg of wheat, part of which he sells at 5% profit and the rest at 20% profit.
\n" ); document.write( " He gains 15% on the whole. Find how much is sold at 5% profit?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt sold at 5%
\n" ); document.write( "then
\n" ); document.write( "(100-x) = amt sold at 20%
\n" ); document.write( ":
\n" ); document.write( "A typical mixture equation
\n" ); document.write( ".05x + .20(100-x) = .15(100)
\n" ); document.write( "solve for x \n" ); document.write( "
