Q. The amount after 2 years at simple interest is Rs. 1210 and the rate is 5% per annum. What was the principal?
✅ Correct Answer: (A)
Rs. 1100
Explanation: With R=5% and T=2, total percent = 1 + (5×2)/100 = 1 + 0.10 = 1.1. So P = Amount/1.1 = 1210/1.1 = 1100. Other options give wrong division results.
