Objective function $z=200x+500y,$ subject to the constraints $x+2y≥10, 3x+4y≤24, x≥0, y≥0,$ the minimum value of z is : |
2500 3000 0 2300 |
2300 |
The correct answer is Option (4) → 2300 $x+2y≥10, 3x+4y≤24, x,y≥0$ finding intersection of $x+2y=10$ ...(1) $3x+4y=24$ ...(2) eq. (2) - 2 × eq. (1) $3x+4y-2x-4y=24-20$ $x=4$ from (1) $y=3$ $z=200x+500y$ checking at corner points $Z_A=3000$ $Z_B=2500$ $Z_C=2300$ → $Z_{min}$ |
