Q. During which time period in Bengal Kapardaka Purana was used?
Answer:
Sena Dynasty
Notes: The term Kapardaka Purana is seen as a medium of exchange in the writings of the Sena kings and other contemporary kings. Karpadak means cow; And 'Purana' is definitely a kind of silver coin. The conjunction ‘kapardaka-purana’ refers to a medium of exchange whose quality is equal to that of a purana or silver coin (56.6 grains), but which is actually calculated by the proportional denominator.
