Specific rotation of sugar solution is 0.5 deg m^2 kg^-1 * 200 kg m^-3 of impure sugar solution is taken in a sample polarimeter tube of length 20 cm and optical rotation is found to be 19^@ . The percentage of purity of sugar is

theta is the optical rotation produced by sugar solution of concentration C and taken in a glass tube of length 0.2 m and radius r . Then the solution is transferred to another glass tube of length 0.3 m and radius r and the remaining space is filled with distilled water. The optical rotation produced by this solution is
