Specific rotations of freshly prepared aqueous solutions of i and ii are +112 and +18.7, respectively. on standing the optical rotation of aqueous solution of i

Specific rotations of freshly prepared aqueous solutions of I and II are +112 and +18.7, respectively. On standing the optical rotation of aqueous solution of I slowly decreases to give a final value of +52.7 due to equilibrium with IIL. Under this state of equilibrium, what is the ratio II: 1?
