Question

Is the statement true or false - If the primal LPP has an unbounded solution, the dual LPP cannot have a feasible solution.

Answer 1

The statement is true, because in a general linear programming problem, if there is a situation of unbounded solution in the primal, then the dual formulated from that problem will definitely produce a result which is infeasible (i.e. a solution that violates at least one of the constraints).
