To calculate your capital after 1 year with a 10% monthly interest rate, compounded monthly, we'll use the compound interest formula again:

$A = P \times \left(1 + \frac{r}{n}\right)^{n \times t}$

Where:

• $P = 15,45,63,405$ (initial capital in Rs)
• $r = 0.10 \times 12 = 1.2$ (annual interest rate)
• $n = 12$ (compounded monthly)
• $t = 1$ year

Let's calculate the final amount $A$.After 1 year, with a 10% monthly interest rate compounded monthly, your capital will be approximately Rs. 48,50,86,176.

Here are some related questions:

1. What would your capital be after 6 months with this new capital amount?
2. How much interest would you earn in the first month alone?
3. What would be the total interest earned after 1 year?
4. How would your capital change if the interest rate was compounded daily instead of monthly?
5. What would be your capital after 2 years under the same conditions?

Tip: The power of compounding is significant, especially with high monthly interest rates. It's essential to understand how it scales over time.
