Given two isomers (anomers) of a sugar with a specific rotational character, knowing the specific rotatoin of the equilibrium mixture, what are the percentages of each in the mix?

Q1. เฟ-D-Galactopyranose has [เฟ]D = +150.7o, and เฟ-D-galactopyranose has [เฟ]D = +52.8o. When either of them is dissolved in water and allowed to reach equilibrium, the specific rotation of the solution will be +80.2o. What are the percentages of each anomer at equilibrium?
