Answer

To find the percentage decrease in revenue of the firm in 2010 with respect to the previous year (2009), we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Revenue for Both Years**:
- Revenue in 2009 = 300 crores
- Revenue in 2010 = 260 crores

2. **Calculate the Decrease in Revenue**:
- Decrease in revenue = Revenue in 2009 - Revenue in 2010
- Decrease in revenue = 300 crores - 260 crores = 40 crores

3. **Calculate the Percentage Decrease**:
- Percentage decrease is calculated using the formula:
\[ \text{Percentage Decrease} = \left( \frac{\text{Decrease in Revenue}}{\text{Revenue in 2009}} \right) \times 100 \]
- Plugging in the values:
\[ \text{Percentage Decrease} = \left( \frac{40}{300} \right) \times 100 \]

4. **Simplify the Calculation**:
- First, simplify \( \frac{40}{300} \):
\[ \frac{40}{300} = \frac{4}{30} = \frac{2}{15} \]
- Now, calculate \( \frac{2}{15} \times 100 \):
\[ \frac{2 \times 100}{15} = \frac{200}{15} \approx 13.33 \]

5. **Conclusion**:
- The revenue of the firm decreased by approximately **13.33%** in 2010 with respect to 2009.
