रैखिक प्रोग्रामिंग समस्या: Minimize cᵀx subject to Ax ≥ b और x ≥ 0 का द्वैत है
  1. Amaximize bᵀw subject to Aᵀw ≥ c and w ≥ 0maximize bᵀw subject to Aᵀw ≥ c और w ≥ 0
  2. Bmaximize bᵀw subject to Aᵀw ≤ c and w ≥ 0maximize bᵀw subject to Aᵀw ≤ c और w ≥ 0
  3. Cmaximize bᵀw subject to Aᵀw ≤ c and w is unrestrictedmaximize bᵀw subject to Aᵀw ≤ c और w अप्रतिबंधित है
  4. DMore than one of the aboveउपर्युक्त में से एक से अधिक
  5. ENone of the aboveउपर्युक्त में से कोई नहीं
Show answerHide answer

Correct answer: (B) maximize bᵀw subject to Aᵀw ≤ c and w ≥ 0maximize bᵀw subject to Aᵀw ≤ c और w ≥ 0

Explanation

For a minimization problem with Ax ≥ b and x ≥ 0 (the canonical form), the dual is: maximize bᵀw subject to Aᵀw ≤ c, w ≥ 0.न्यूनतमीकरण समस्या Ax ≥ b, x ≥ 0 (मानक रूप) का द्वैत है: bᵀw अधिकतम करें, प्रतिबंध Aᵀw ≤ c, w ≥ 0।
