Step-by-step Solution
To calculate the simple interest (SI) and the total amount (A) for a principal amount (P) of ₹ 8250 at an interest rate (r) of 6% per annum for a time period (t) of \( 3 \frac{1}{2} \) years, we can use the following formulas:
1. **Simple Interest (SI)**:
\[
SI = \frac{P \times r \times t}{100}
\]
2. **Total Amount (A)**:
\[
A = P + SI
\]
### Step 1: Convert the time period
First, convert \( 3 \frac{1}{2} \) years into a decimal:
\[
3 \frac{1}{2} = 3 + \frac{1}{2} = 3.5 \text{ years}
\]
### Step 2: Calculate Simple Interest
Now, substitute the values into the SI formula:
- \( P = 8250 \)
- \( r = 6 \)
- \( t = 3.5 \)
\[
SI = \frac{8250 \times 6 \times 3.5}{100}
\]
Calculating the above:
\[
SI = \frac{8250 \times 6 \times 3.5}{100} = \frac{173250}{100} = 1732.50
\]
### Step 3: Calculate Total Amount
Now, calculate the total amount using the formula:
\[
A = P + SI
\]
\[
A = 8250 + 1732.50 = 9982.50
\]
### Final Results
- **Simple Interest (SI)**: ₹ 1732.50
- **Total Amount (A)**: ₹ 9982.50
Quick Answer
Simple Interest: ₹ 1732.50, Total Amount: ₹ 9982.50
