1. What is Simple Interest?

Simple interest is a method of calculating interest on a loan or investment where interest is calculated only on the principal amount, not on any accumulated interest. It's commonly used for personal loans in India.

Where:

• \( I \) — Interest amount (₹)
• \( P \) — Principal amount (₹)
• \( r \) — Annual interest rate (decimal)
• \( t \) — Time period (years)

Explanation: The formula calculates interest by multiplying the principal amount by the annual interest rate (converted to decimal) and the time period in years.
