Latest Answer: Hi Shreya,
It definitely is refreshing to hear that the Mumbai proposal is the lowest among the 10 major cities. However, I am skeptical as to how far this will remain accurate when it comes to the implementation of the project. If we look at the past project proposals both in Mumbai as well as other cities in the country we an see that more often that not they have overshot their initial estimate. While the low proposal is still welcome, I doubt that the project will be able to stick to it's proposal considering the high amounts of corruption, bureaucracy etc.
