Step 1: Formula for Simple Interest.
The formula for calculating simple interest is:
\[
\text{Simple Interest} = \frac{P \times R \times T}{100}
\]
Where:
\( P \) is the principal amount,
\( R \) is the rate of interest per annum, and
\( T \) is the time in years.
Step 2: Apply the given values.
Here,
\( P = 15,000 \),
\( R = 8\% \),
\( T = 2 \, \text{years} \).
Now substitute the values into the formula:
\[
\text{Simple Interest} = \frac{15,000 \times 8 \times 2}{100} = \frac{240,000}{100} = 2400
\]
Step 3: Conclusion.
Therefore, the simple interest is ₹ 2400.
Final Answer: ₹ 2400.
