The corner points of the feasible region determined by the system of linear inequalities are $(0,3), (1,1)$ and $(3,0)$. Let $Z = px + qy$ where $p, q > 0$. Find the condition on $p$ and $q$ such that the minimum of $Z$ occurs at both $(3,0)$ and $(1,1)$.

  • A
    $p = 2q$
  • B
    $p = \frac{q}{2}$
  • C
    $p = 3q$
  • D
    $p = q$
