Doing as volume parts, alcohol : water,\r

\n" ); document.write( "\n" ); document.write( "\"%2812%2F17%29%2As%2F%28s%2B14%29=4%2F7\" using s for quantity of the starting mixture. The proportion here presented is parts per mixture, numerator being the parts as alcohol.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The question asked for \"quality\" of the alcohol in the mixture. A more sensible question would be, what QUANTITY of the 12:5 MIXTURE was used to prepare the 4:3 alcohol-to-water mixture. Solving for s will give that answer.
