The problem asks to calculate the "Total Amount" (कुल राशि) and the "Compound Interest" (चक्रवृद्धि ब्याज) for the given principal, time, and interest rate. Let's go step by step.

### Given:
- Principal (P) = ₹ 10,800
- Rate of Interest (R) = \( 12\frac{1}{2} \)% = 12.5% per annum
- Time (T) = 3 years
- Compound Interest is compounded annually.

#### Formula for Compound Interest:
\[
A = P \left( 1 + \frac{R}{100} \right)^T
\]
Where:
- \( A \) is the amount (Total sum after interest),
- \( P \) is the principal,
- \( R \) is the rate of interest,
- \( T \) is the time in years.

Compound Interest (CI) is:
\[
CI = A - P
\]

### Step 1: Calculate the Total Amount (A)
Using the formula for compound interest:
\[
A = 10800 \left( 1 + \frac{12.5}{100} \right)^3
\]
\[
A = 10800 \left( 1 + 0.125 \right)^3 = 10800 \left( 1.125 \right)^3
\]

Now, calculate \( (1.125)^3 \):
\[
(1.125)^3 = 1.423828125
\]

Thus:
\[
A = 10800 \times 1.423828125 = 15377.35
\]

### Step 2: Calculate the Compound Interest (CI)
\[
CI = A - P = 15377.35 - 10800 = 4577.35
\]

### Final Results:
- Total Amount (A) = ₹ 15,377.35
- Compound Interest (CI) = ₹ 4,577.35

### Related Questions:
1. How would the result change if interest was compounded quarterly?
2. What would be the total amount if the interest rate was reduced to 10%?
3. How is simple interest different from compound interest in this scenario?
4. How can we calculate the rate of interest if the compound interest and amount are known?
5. What is the formula for continuous compounding of interest?

#### Tip:
Always ensure to convert the interest rate correctly (e.g., \( 12 \frac{1}{2} \)% to 12.5%) before applying it to formulas.
