In 1980 1USD=7.8 INR
If every country currency started at the same time with a 1 to 1 exchange rate to others, you could say that since that time, a country with a more expensive currency has had a stronger economy, more or less. However, this is not the case. Exchange rates are fixed at various times in history and they can change at any moment if the government decides to do it. For instance, for those two currencies, here are the exchange rates to the US dollar over some years: "Currency Code 2000 1990 1980 1970 1960 1950 Indian Rupee INR 44.942 17.505 7.8629 7.5 4.7619 4.7619 Japanese Yen JPY 107.76 144.79 226.74 360 360 361.1 " Source: http://en.wikipedia.org/wiki/List_of_historical_exchange_rates This gives following value of the Indian rupie in yen over the years: 2000 1990 1980 1970 1960 1950 2.40 8.27 28.84 48.00 75.60 75.83 So if one Indian rupie is 2.40 yen in 2000, it was 75.83 yen in 1950. Since that time, it has always lost in value in comparison to the yen.
