If an LPP admits optimal solution at two consecutive vertices of a feasible region, then

Options

  1. Athe required optimal solution is at the midpoint of the line joining two points.
  2. Bthe optimal solution occurs at every point on the line joining these two points
  3. Cthe LPP under consideration is not solvable
  4. Dthe LPP under consideration must be reconstructed

Correct answer

B. the optimal solution occurs at every point on the line joining these two points

Step-by-step solution

If an LPP admits optimal solution at two consecutive vertices of a feasible region, then the LPP under consideration is not solvable.
