Earn 12.5% compound interest per annum on your investment.

It seems you're referring to the Maharashtra Vikas (Maha Vikas) Scheme, which is a government-backed investment option offering an interest rate of around 12.5% per annum on investments.

This is usually a long-term scheme aimed at generating steady returns with compound interest. Typically, these types of schemes are designed to encourage saving and investing in a safe manner, especially with attractive interest rates like the one you mentioned (12.5% annually).

However, I don't have details about a specific current "Maharashtra Vikas" scheme offering this exact rate, so I would recommend checking the official website of Maharashtra Government or a reliable financial institution for specific details like:

·         The terms and conditions (lock-in period, minimum investment),
