1. Corner points are O(0, 0), A(5, 0), B(3, 4), C(0, 5).
2. Constraints are 2x + y ≤ 10, x + 3y ≤ 15, x ≥ 0, y ≥ 0.
3. At (3, 4), Z = 3p + 4q
At (5, 0), Z = 5p
⇒ 3p + 4q = 5p ⇒ p = 2q.
4. If q = 1, p=2
Then the objective function is,
Maximize Z = 2x + y.
5. At (3, 4) Z = 2 × 3 + 4 = 10 is the maximum value.
