Dear Mr.Sudipta Kumar Gogoi,
At the time of finalization of order, we have considered 6" size HMI.  But for your standardization, you require 11" size HMI.  The price difference between 6" and 11" HMI of Mitsubhi make is Rs.73,000/-   So kindly confirm whether you can send the amendment for this additional price of 11" size HMI.  After receipt of your confirmation, we will order the new HMI.         
                                   M. S. Nimbalkar
