PRC-2 · Chapter 4 · Question 12 of 60
Identify the redundant constraint in the following system: x ≤ 5, y ≤ 6, and x ≤ 10.
Test yourself: pick an answer
Reveal answer & explanation
Correct answer: C) x ≤ 10
Explanation
Because the constraint x ≤ 5 already strictly limits the value of x to 5 or less, the constraint stating x must be ≤ 10 is redundant; it provides no additional restriction on the feasible region.
