Question

what was the exchange rate dollar and rupee on August 15 1947?

Answer 1

At the time when India gained independence in 1947, there were no debts to be found in the Indian balance sheet so the value of both currencies were at par.

The Indian rupee was fixed to the British pound as one rupee = one shilling and six pence.

It is assumed that then the British pound = 4USD (approx). So 1 USD was more than 3 rupees.
