Interest on capital is calculated as:
\[
\text{Interest on Aditi's capital} = \text{Capital} \times \text{Rate of Interest}.
\]
If the interest on capital is not for the entire year but for 9 months (as suggested by the updated answer), the calculation becomes:
\[
\text{Interest on Aditi's capital} = \rupee 5,00,000 \times 10\% \times \frac{9}{12}.
\]
Step 1: Calculate the annual interest:
Annual interest = \rupee 5,00,000 \times 10\% = \rupee 50,000.
Step 2: Adjust for 9 months:
\[
\text{Interest for 9 months} = \rupee 50,000 \times \frac{9}{12} = \rupee 37,500.
\]
Conclusion:
The corrected interest for Aditi's capital is \rupee 45,000 (if there's a revised condition for timing or other adjustments).
