stackrel(+II)(Mn), stackrel(+V)(N), stackrel(-II)(O),

Explanation:

The sum of the oxidation numbers is equal to the charge of the ion. Here, we have a neutral salt, and thus the sum of the oxidation numbers is 0.

The salt derives from Mn^(2+), and from 2 equiv NO_3^-. With respect to nitrate anion, the oxidation number of oxygen is generally -II, and it is here. Nitrogen is fully oxidized in the +V state.
