(Unless Rs. isn't Rupee, but Google thinks it is)
You need to be able to trust a book. I received a misprint of a book I ordered online once, duplicate pages, missed half a chapter. I didn't need that particular chapter for the course I was taking then, and it was a week before the exam so I didn't send it back, it's a really cool book (Computational Geometry) that, like other interesting study books, I would pick up again and browse occasionally, if it weren't for this mess up. It's a shame, really.
That said, lunch in the company cafeteria was about 50 Rs, if I recall. So, where I would spend about 5 to 8 USD at home on a modest lunch, they would spend what amounted to 1 USD. Salaries are scaled accordingly, so yeah, those Rupees come dearly when you have to earn them locally.
100 Rs might exchange for 2 USD, but it feels like having to earn 10 USD (or more).
Also over the past year, the value of dollar has increased to Rs 67(or the value of Rupee has fallen, whatever). The point is, it burns more now. And the burn amount keeps fluctuating.
Apologies if I am pedagogical but it is "Gandhi" and not "Ghandi".
