For the next 6 numbers: Consider the Transportation table given below. In the MODI method with initial solution: XA1=20,XA2 =30,XB2=40,XC2=25,XC3=35., after the first iteration, which variable included in the closed path of the stepping stone did not change its value? xB2xC3xA3xA2 Using VAM, what is the total cost? \begin{tabular}{c} $555 \\ \hline$600 \\ \hline$730 \\ \hline$690 \end{tabular} Use the Stepping Stone method with initial solution: XA1= 20,XA2=30,XB2=40,XC2=25,XC3=35. After the first iteration, which variable included in the closed path did not change its value? XA2 XC3 XA3 XB2 In the MODI method with initial solution: XA1=20,XA2 =30,XB2=40,XC2=25,XC3=35., In the first iteration, in what cell should the stepping stone start? cell B1 cell A3 cell B3 cell C1 Usng the Vogel's Approximation Method, in the first iteration, which cell is first given allocation, how many units? XA2=50XB1=20XC2=60XC3=35 In the MODI method with initial solution: XA1=20,XA2 =30,XB2=40,XC2=25,XC3=35. What is the value of the index used as basis for the starting point of the stepping stone? 1 7 1 2
