Let n be the amount of 60% alcohol. Then the amount of 30% alcohol would be 90-n. So:
\n" ); document.write( ".6n+.3(90-n)=.5(90)
\n" ); document.write( ".3n+27=45
\n" ); document.write( ".3n=18
\n" ); document.write( "n=60
\n" ); document.write( "60 liters of .6 alcohol and 30 liters of .3 alcohol will give you the desired mixture. ☺☺☺☺
\n" ); document.write( "
\n" );
