U havnt estimated any cost yet..didnt hav any answer for 16-18% diff in UP/DN Kalka/DBRG...just a dinner or lunch provision could add in 18% in cost, thn u easily could compute the overall catering impact!!
Further, Taj may come in smaller bracket (maybe 10-20000 lesser), but do this make much of impact, as still Just Electric/Fuel Cost will impact its return!! I made example of Taj, to nullify 70% input of cost for only energy!! M not estimating bt 70% & Kms direct ratio is incorrect,,yeah fuel charge proportional to Km run, makes sence (but its total cost not just fuel)!!
