Linear Programming

Question:

Which of the following is a correct set of constraints for a linear programming problem ?

Options:

$x+2y ≤50, 3x+y ≤ 80, x≥0, y ≥ 0$

$x+2y ≤50, 3x^2+y^2 ≤ 80, x≥0, y ≥ 0$

$x+2y ≤50, 3x+y ≥ 80, x≤0, y ≥ 0$

$x+2y ≥50, 3x+y ≥ 80, x ≥0, y ≤ 0$

Correct Answer:

$x+2y ≤50, 3x+y ≤ 80, x≥0, y ≥ 0$

Explanation:

The correct answer is Option (1) → $x+2y ≤50, 3x+y ≤ 80, x≥0, y ≥ 0$

Option 2: The inequality is quadratic.

Option 3 & 4: Non-negativity constraint is not followed.

Option 1: All inequalities are linear, and non-negativity is followed. Therefore it is a valid set of constraints.
