2500 crore is very close to 430million dollars, so the cost hasn’t swelled by any significant measure, and yet you’re mentioning an outflow of 38.7 billion, that Number is incorrect, both in dollars and in rupee terms.

Not to mention that you were able to estimate something like “outflow” so simply.

maybe you meant millions? And even if you did, you are still very likely to have grossly miss-estimated that figure, as it would be inclusive of foreign labour, engineering and consulting costs.

You did good by bringing in sources, but the way you have interpreted it all, makes me wonder if there’s something really wrong with your brain.
