Too Much Match II

You roll two fair $n-$sided die with the values $1-n$ on the sides. Let $A$ and $B$ be disjoint subsets of the sample space of all possible pairs of rolls. If the outcome rolled is in $A$, you receive $€p$. If the outcome rolled is in $B$, you pay $€q$. If you receive anything else, you re-roll with no penalty until one of the two above outcomes occurs. If $p$ is fixed, find the maximum value of $q$ such that the game has non-negative expected payout when $p = 100, n = 10, |A| = 25,$ and $|B| = 50$.
