Was just curious about how many languages are there on Indian notes. Here is some information extracted from RBI website for ten rupees note.
There are fifteen Indian languages on almost all notes, excluding English and Hindi. This clearly indicates how India is rich in culture and heritage. These are only official languages but there are many more languages exist in India since last centuries. The language panel of Indian Currency also depicts the ‘Unity in Diversity’. Following table shows how a rupee is written in different languages and pronounced in Marathi. Added small drop of knowledge by sharing this information.
