उत्तर

‘915 fine silver’ consists of 91.5% silver.

Explanation:

The number ‘915’ in 915 fine silver means that the silver contains 91.5% pure silver. The remaining 8.5% is usually copper or other metals to improve hardness. Pure silver is too soft to be used for jewellery or coins, so it is alloyed.
