Specific Rotation

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

1. $0.57$
2. $1.00$
3. $1.75$
4. $5.9$
