Question
To write the dual; it should be ensured that
  1.  All the primal variables are non - negative.
  2. All the bi values are non - negative.
  3. All the constraints are $\leq$ type if it is maximization problem and $\geq$ type if it is a minimization problem.

Answer

  1. I and III

Solution:

To write the dual, then all the primal variables must be non-negative.

All the constraints are $\leq$ type if it ia maximization problem and $\geq$ type if it is a minimization problem.
