how many paise in 1 aana?
An anna (or ānna) was a currency unit formerly used in British India, equal to ​1⁄16 of a rupee. It was subdivided into four (old) Paisa or twelve pies (thus there were 192 pies in a rupee). When the rupee was decimalised and subdivided into 100 (new) paise, one anna was therefore equivalent to 6.25 paise.
