  1. Solve the following LPP graphically. Maximize Z = 6x1 + 5x2 Subject to the constraints 3x1 + 5x2 ≤ 15, 5x1 + 2x2 ≤ 10 and x1,x2 ≥ 0

  2. Solve the following LPP graphically. Maximize Z =−x1 + 2x2
    Subject to the constraints −x1 + 3x2 ≤ 10, x1 + x2 ≤ 6,x1 − x2 ≤ 2 and x1,x2 ≥ 0

  3. Solve the following LPP graphically. Minimize Z = x1 − 5x2 + 20
    Subject to the constraints x1 − x2 ≥ 0,−x1 + 2x2 ≥ 2,x1 ≥ 3,x2 ≤ 4 and x1,x≥ 0.

  4. Solve the following LPP graphically. ∴ Maximize Z = 3x1 + 4x2  subject to the constraints x1 + x2 ≤ 4 and x1,x2 ≥ 0.
