Ratio and Proportion amigo.
\n" ); document.write( "let \"x\"= amount in liters
\n" ); document.write( "so, (300/0.76) = (x/0.20)
\n" ); document.write( "x=(300*0.20) / 0.76
\n" ); document.write( "x=79 liters
\n" ); document.write( "therefore \"300-79+=+221+liters\" to be Extracted
\n" ); document.write( "Thank you
