Which assumption of linear programming means that the contribution of each activity is directly proportional to its level?
Correct answer: A. Proportionality
- A. Proportionality
- B. Divisibility
- C. Certainty
- D. Non-negativity
Explanation
Proportionality means that resource use and contribution to the objective change in direct proportion to each activity level. Divisibility concerns fractional values, while certainty concerns known coefficients.

About Linear Programming
Linear programming models the maximum or minimum of an objective function subject to linear constraints. Questions involve translating word conditions into inequalities, drawing the feasible region, identifying corner points and evaluating the objective function, including cases involving non-negativity restrictions and redundant constraints.
