how much water is to be evaporated from 20 liters of 20 percent sugar solution to get 30 percent sugar solution.
\n" ); document.write( "--------
\n" ); document.write( "Equation:
\n" ); document.write( "water - water = water
\n" ); document.write( "0.80*20 - 1*x = 0.70(20-x)
\n" ); document.write( "-----
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "80*20 - 100x = 70*20 - 70x
\n" ); document.write( "30x = 10*20
\n" ); document.write( "x = (1/3)20 = 6 2/3 Liters (amt. of water to evaporate)
