  • You should show the work you did and the answer you got so that we may be able to see where you encountered difficulty. Also, the extraneous table at the top of the photo makes this question confusing even with the explanation, and even if it were cropped better we like to avoid showing photographs of formulas and tables when it can be avoided. You can format a copy of the table using advice here: https://math.meta.stackexchange.com/questions/5020/mathjax-basic-tutorial-and-quick-reference – David K Mar 24 '17 at 13:02
  • I get 229km for VAM assuming 0 penalty costs for unused trucks. Note that the VAM does not necessarily give the minimal solution. – Paul Mar 24 '17 at 13:07
  • I got 221. If you edit the question to show your work (that is, show each step you took), I could indicate where we differ. It is a lot of work to type in all those details, I understand, but can you understand why it makes more sense for you to do that than for me to do it? – David K Mar 24 '17 at 13:44
  • Pls upload ur working .i will match my working with urs. Thnks. – T.Noor Mar 24 '17 at 14:02
  • @David K, I get 229 for VAM then 221 after stepping stone (minimal solution). – Paul Mar 24 '17 at 14:26
  • @Paul I suppose it's possible I overlooked a row or column I was supposed to work on next according to the method and by dumb luck this mistake led to the optimal answer. I just learned the method in order to work on this question. But until someone writes it up step by step (and I still think OP should be the one to do it), we have no way to check for such errors. – David K Mar 24 '17 at 14:46
  • @David K - the OP definitely should! – Paul Mar 25 '17 at 11:40
