Step 1: Identify the given values. The problem states the following: • Simple Interest (SI) = 648 रुपये • Rate of Interest (R) = 12% per annum • Time (T) = 3 years Step 2: Use the formula for Simple Interest. The formula for simple interest is: SI = (P × R × T)/(100) Where P is the Principal amount. Step 3: Rearrange the formula to solve for the Principal (P). To find the principal amount, we can rearrange the formula: P = (SI × 100)/(R × T) Step 4: Substitute the given values into the formula and calculate P. P = (648 × 100)/(12 × 3) P = (64800)/(36) P = 1800 The principal amount is 1800 रुपये. Comparing this with the given options: 1) 2100 2) 1100 3) 1800 4) 2200 The calculated principal matches option 3. The final answer is 3) 1800.
