Abstract. Let $a$, $b$, $c$, $p$, $q$ be given positive integers with $a = pq$ and let $g(z)$ and $h(z)$ be positive integer valued arithmetical functions such that there is no integer between $g(z)/p$ and $h(z)/q$ for any positive integer $z$. Consider the ternary diophantine equation $(py + g(z))(qy + h(z)) = ax^{2} + bx + c$ in variables $x$, $y$, $z$. In this paper, we find a real number $\gamma$ such that all positive integral solutions $(x, y, z)$ of the equation satisfy $x \le \gamma$.
