The national currency of India is the Indian Rupee, abbreviated as INR. The symbol for the rupee resembles the combination of the Latin letters 'R' and 'Rs.' and is often denoted by the sign '₹'. The Indian Rupee is further subdivided into 100 paise. It was established as the official currency in 1540 and has undergone several changes and reforms since. The Reserve Bank of India is responsible for issuing and regulating the currency, playing a vital role in the country's economic stability and growth.
