V. Consider the transporation problem with the parameter table below. Use least cost method (LCM), northwest corner method (NCM), and Vogel's approximization method (VAM) to get an initial solution. Is this solution optimal? Use stepping stone method to get the optimal solution if necessary. Show improvement index for all blank cells.
