------------------------ percent ---------------- quantity
\n" ); document.write( "Solution Type I 12 ---------------- 5 ml
\n" ); document.write( "solution type II 30 ---------------- x ml
\n" ); document.write( "Mixture 20 ---------------- 5 + x ml
\n" ); document.write( "The sum of individual contents of the two types of components =content in mixture
\n" ); document.write( "12*5+30x=20(5+x)
\n" ); document.write( "60+30x =100+20x
\n" ); document.write( "30x-20x=100-60
\n" ); document.write( "10x=40
\n" ); document.write( "/10
\n" ); document.write( "x=4 ml of solution type II
