The minimum value of $Z = 3x + 2y$ subjected to the constraints $2x + y ≥7,x + 2y ≥8;x, y ≥ 0$ is |
24 10 12 14 |
12 |
The correct answer is Option (3) → 12 ** Feasible region comes from the constraints: $2x+y\ge 7,\; x+2y\ge 8,\; x\ge 0,\; y\ge 0$ Evaluate $Z=3x+2y$ at all feasible corner points: At $(0,7)$: $Z=3(0)+2(7)=14$ At $(8,0)$: $Z=3(8)+2(0)=24$ At $(2,3)$: $Z=3(2)+2(3)=12$ The minimum value of $Z$ is $12$. |
