What is the relationship between us dollar and Indian rupee?

Answer 1

currency appreciates means its value has increased in relation to another currency.If one US dollar is equal to 45 rupees, it simply means that in the US, if a dollar fetches 45 Oranges while in India, a rupee would fetch only one orange of equivalent size and quality.

Just like any other commodity, the currency of any economy is based on dynamics of supply and demand, and its value depends on trading in currency exchanges all over the world. Higher the demand for a currency on an exchange, the stronger it becomes and vice versa. However, for currencies like INR which are not traded on exchanges, the value depends on capital inflows in the country.
