Question

Maximize Z = 5x1+12x2+4x3

Subject to,

x1+2x2+x3 <=0

2x1-x2+3x3 =8

And x1,x2,x3 >=0

The optimum tableau for the primal problem using Big M method is

Basic x1 x2 x3 x4 R Solution 
Z 0 0 3/5 29/5 (-2/5)+M 54.8
x2 0 1 -1/5 2/5 -1/5 12/5
x1 1 0 7/5 1/5 2/5 26/5

      

Find the optimal solution for the corresponding dual problem using two methods. Also, deduce the primal Z-equation coefficients of the xi,s from the dual constraints.
