Statement 1 is correct. Purchasing Power Parity (PPP) exchange rates are calculated by comparing the prices of a common basket of goods and services in different countries. The idea is to determine how much currency 'A' is needed in country 'A' to buy the same basket of goods that currency 'B' buys in country 'B'. The PPP exchange rate is the rate at which the currency of one country would have to be converted into that of another country to buy the same amount of goods and services in each country. Statement 2 is incorrect. In terms of PPP dollars, India is the third largest economy in the world, after China and the United States. This ranking has been consistent in data provided by international bodies like the International Monetary Fund (IMF) and the World Bank in recent years.
