    In order to solve it, you would have to assume that no student studies more or fewer than two languages.

    As it stands it's an incomplete question - ie it's impossible to tell from the data provided.  I would guess that there is more to the question than you may have thought relevant.  ie from the data we have are there any students learning either no or three languages.

    With the incomplete data the only answer is somewhere between 10  and 30!
