document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Ans:\r\n" );
document.write( "Let the volume of water to be mixed be x ml\r\n" );
document.write( "Total volume of the mixture = (x+12) ml\r\n" );
document.write( "\r\n" );
document.write( "If this is to be 12% alcohol solution, that means that the *mixture* contains\r\n" );
document.write( "12% of alcohol by volume.\r\n" );
document.write( "\r\n" );
document.write( "We know that the mixture has 12 ml of alcohol.\r\n" );
document.write( "\r\n" );
document.write( "So, we get the equation - 12/(x+12) = 12% or 12/100\r\n" );
document.write( "\r\n" );
document.write( "\"12%2F%28x%2B12%29+=+12%2F100\"\r\n" );

document.write( "\"1%2F%28x%2B12%29+=+1%2F100\"\r\n" );

document.write( "Cross multiplying\r\n" );
document.write( "\r\n" );
document.write( "\"x+%2B+12+=+100\"\r\n" );
document.write( "\r\n" );
document.write( "x = 88 ml\r\n" );
document.write( "\r\n" );
document.write( "Need  to add 88 ml of water to make it a 12% alcohol solution.\r\n" );
