This source https://en.m.wikipedia.org/wiki/Indian_rupee_exchange_rate_h... seems to suggest that the exchange rate was 1 USD < 20 INR throughout 1990. In fact, the exchange rate doesn't seem to have hit 50 until over twenty years later.

It was simply a correction to the following portion: "6,000 INR / month (120$/month, exchange rate was 50 back then)". Assuming the accuracy of the salary, it appears the following is more accurate: "6,000 INR / month (300$/month, exchange rate was 20 back then)".
