Question

Given the following statements with respect to linear programming problem:

S1: The dual of the dual linear programming problem is again the primal problem

S2: If either the primal or the dual problem has an unbounded objective function value, the other problem has no feasible solution

S3: If either the primal or the dual problem has a finite optimal solution, the other one also possess the same, and the optimal value of the objective functions of the two problems are equal.

Which of the following is true?

• A. S1 and S2
• B. S1 and S3
• C. S2 and S3
• D. S1, S2 and S3

Answer 1

all 3 statements are correct as they all  are properties of dual and primal

hence ans should be D
