#### Question

Maximise Z = x + 2y subject to the constraints

`x + 2y >= 100`

`2x - y <= 0`

`2x + y <= 200`

Solve the above LPP graphically

#### Solution

x + 2y ≥ 100

`x/100 + y/50` >= 1 ....(i)

`2x - y <= 0`

x | 10 | 20 | 30 |

y | 20 | 40 | 60 |

(x,y) | (10,20) | (20,40) | (30,60) |

∴ Z is maximum at 0, 200 & max Z = 400

Is there an error in this question or solution?
