Consider the following LPP:
Min $Z=2x_1+x_2+3x_3$
Subject to:
$x_1 – 2x_2+x_3 \geq 4$
$2x_1+x_2+x_3 \leq 8$
$x_1-x_3 \geq 0$
$x_1, x_2, x_3 \geq 0$
The solution of this LPP using Dual Simplex Method is
- $x_1=0, x_2=0, x_3=3$ and $Z=9$
- $x_1=0, x_2=6, x_3=0$ and $Z=6$
- $x_1=4, x_2=0, x_3=0$ and $Z=8$
- $x_1=2, x_2=0, x_3=2$ and $Z=10$
