A litre of Fuel Costs Rs. 75 to 80 and the graph is constantly increasing with time, giving us a travelling capacity of 37 miles (60 kms) in one go, whereas by putting just 1 unit of electricity in Bravo, gives you more than twice the travelling miles, i.e. 80 miles (130 kms). And what's best, when we can clearly see that 1 unit cost is just Rs.7/km Cost = 0.25.
