document.write( "Question 1150460: A container filled with 30 litres of wine had 5 litres of the wine removed. To fill the container, 5 liters of water was added. The next day 12 litres of the mixture was removed, and replaced with an equal amount of water. What fraction of the final mixture was water? \n" ); document.write( "

\r\n" );
document.write( "After day 1, you have 30 liters of mixture, containing 25 liters of wine and 5 liters of water.\r\n" );
document.write( "\r\n" );
document.write( "The proportion water to total is   =   in volumes.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "When next day 12 liters of the mixture was removed,  30-12 = 18 liters of mixture remained in the container.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "These 18 liters of the mixture contain   volume of water, i.e.   = 3 liters of water.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "When 12 liters of water was added, then the total volume of water in the mixture became 3 + 12 = 15 liters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus final fracture of water is   =   of the total volume.      ANSWER\r\n" );
