The simple interest on a certain sum computes to रु 600 in 3 years and the compound interest on the same sum, at the same rate and for 2 years computes to रु 410. Find the rate per cent.

Explanation

To find the rate of interest per cent based on the information provided, we can follow these steps:

### Step 1: Understand the Simple Interest (SI) Calculation
The simple interest for 3 years is given as ₹600. Since simple interest is the same each year, we can find the interest for one year.

**Calculation:**
\[
\text{SI for 1 year} = \frac{\text{Total SI}}{\text{Number of years}} = \frac{600}{3} = ₹200
