The corner points of the bounded feasible region determined by a system of linear constraints are $(0, 3), (1, 1)$ and $(3, 0)$. Let $Z = px + qy$, where $p, q > 0$. The condition on $p$ and $q$ so that the minimum of $Z$ occurs at $(3, 0)$ and $(1, 1)$ is: |
$p = 2q$ $p = \frac{q}{2}$ $p = 3q$ $p = q$ |
$p = \frac{q}{2}$ |
The correct answer is Option (2) → $p = \frac{q}{2}$ ## $Z = px + qy$ — (i) At $(3, 0)$, $Z = 3p$ — (ii) and at $(1, 1)$, $Z = p + q$ — (iii) From (ii) & (iii), $3p = p + q$ $⇒2p = q ⇒ p = \frac{q}{2}$ |
