The difference between the compound interest and simple interest on a certain sum at 15% per annum for 3 years is Rs 283.50. Find the sum.

Explanation

To find the sum based on the given information about the difference between compound interest (CI) and simple interest (SI), we can follow these steps:

### Step 1: Understand the formula for Compound Interest and Simple Interest
- **Simple Interest (SI)** is calculated using the formula:
\[ SI = \frac{P \times R \times T}{100} \]
where \( P \) is the principal amount (the sum), \( R \) is the rate of interest per annum, and \( T \) is the time in years.
