History

Sher Shah Suri was the first to issue the coin called Rupia in the Indian subcontinent during his reign in the 16th century. This coin later influenced the currency systems in the region.

The 1881 census, often cited as the first fully executed decennial census, was conducted after Lord Mayo's tenure, during the period leading up to Lord Dufferin's administration, but Lord Dufferin was not the Viceroy at the time of the 1881 census. Therefore, the correct answer is Lord Mayo.
