A designer considers all possible rectangular tiles labeled by integer coordinates $(a, b)$ with $1 \le a \le 25$ and $1 \le b \le 25$. A tile is called *acceptable* if its dimensions satisfy $$25b^{2} + 10a^{2} - 18ab \le 7786.$$ She numbers the acceptable tiles from $1$ up to the total number of acceptable tiles, $|S...
