The description and question make no physical sense, but here is the arithmetic:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "d for 40% solution, u for 60% solution.
\n" ); document.write( " $\"%28.4%2Ad%2B.6%2Au%29%2F%2810%29=.56\"$
\n" ); document.write( " $\"40%2Ad%2B60%2Au=560\"$
\n" ); document.write( " $\"4%2Ad%2B6%2Au=56\"$
\n" ); document.write( " $\"2%2Ad%2B3%2Au=28\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Want to have 10 fluid ounce, so $\"d%2Bu=10\"$ . If multiply both sides of this one by 2, we get equivalent equation, $\"2d%2B2u=20\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If we now subtract $\"2d%2B2u=20\"$ from $\"2%2Ad%2B3%2Au=28\"$ , we get u = 8 fluid ounces. value for d can be easily computed. \n" ); document.write( "

\n" );
