Options

A. 270
B. 240
C. 210
D. 230

Answer

To find the Simple Interest (S.I.) for the given principal amount, rate of interest, and time period, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the given values:**
- Principal (P) = Rs. 1800
- Rate of Interest (R) = 5% per annum
- Time (T) = 3 years

2. **Use the formula for Simple Interest:**
\[ \text{Simple Interest (S.I.)} = \frac{P \times R \times T}{100} \]

3. **Substitute the values into the formula:**
\[ \text{S.I.} = \frac{1800 \times 5 \times 3}{100} \]

4. **Calculate the multiplication in the numerator:**
- First, calculate \( 1800 \times 5 = 9000 \)
- Then, calculate \( 9000 \times 3 = 27000 \)

5. **Now divide by 100:**
\[ \text{S.I.} = \frac{27000}{100} = 270 \]

6. **Final Result:**
The Simple Interest is Rs. 270.
