Worked practice questions

A linear programming problem must have constraints that are:

  1. Curved
  2. Random
  3. Linear
  4. Cubic
Show answer and solution

Correct answer: C. Linear

1. The name of the method gives it away. 2. Every restriction is written as a linear inequality or equation. 3. So the constraints are linear. 4. The answer is linear. _Source: syllabus Mathematics, Ch 12 'Linear Programming'_
