Formula Explanation
SI = (P × R × T) / 100
Where:
P = Principal Amount
R = Annual Interest Rate (%)
T = Time (Years)
Total Amount = Principal Amount + Simple Interest
Example:
If Principal = ₹100,000, Rate = 6%, and Time = 5 Years:
Simple Interest = (100000 × 6 × 5) / 100 = ₹30,000
Total Amount = ₹130,000
