You can put this solution on YOUR website!
1st solution = x
\n" ); document.write( "2nd solution = y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "20% * x + 60% * y = 50% * (x + y)
\n" ); document.write( "0.2x + 0.6y = 0.5(x + y)
\n" ); document.write( "0.2x + 0.6y = 0.5x + 0.5y
\n" ); document.write( "0.6y - 0.5 y = 0.5x - 0.2x
\n" ); document.write( "0.1y = 0.3x
\n" ); document.write( "y/x = 0.3/0.1
\n" ); document.write( "y/x = 3/1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, the ratio will be:
\n" ); document.write( "solution 1(20%) : solution 2(60%) = 1 : 3
\n" ); document.write( "
\n" ); document.write( "
\n" );
