3. While solving a standard form problem, we arrive at the following tableau, with 3 and 2, being the basic variables. XB Z I 12 23 A Z 1 0 B 0 20 320 13 0 0 1 2 -1 8 21 0 1 Y 0 CY 8 The entries a, B, in the tableau are unknown parameters. (a) Suppose the LP problem was a minimization problem, give the range of values of the unknown parameters, that would make the optimal cost be -0. (b) Suppose the problem was a maximization problem, give the range of values of the unknown parameters, that would make the current solution to be optimal. Hence state the optimal solution. (c) Suppose that it is a maximization problem and that ẞ= -10, a == explain why the current solution is feasible but not optimal. Hence proceed and determine the optimal solution.
