The 6% solution will increase to 10%, an increase of 4%.
\n" );
document.write( "The 14% will be reduced to 10%, a reduction of 4%. 
\n" );
document.write( "Therefore, the same amount of 6% and 14% solutions need to be mixed. 
\n" );
document.write( "So, 6 liters of each is needed. 
\n" );
document.write( "OR
\n" );
document.write( "Let amount of 14% solution to mix, be F
\n" );
document.write( "Then we get: .06(6) + .14F = .1(6 + F)
\n" );
document.write( ".36 + .14F = .6 + .1F
\n" );
document.write( ".14F - .1F = .6 - .36
\n" );
document.write( ".04F = .24
\n" );
document.write( "Amount of 14% solution to mix, or  \n" );
document.write( "

\n" );
