Show answer & explanation
Correct answer: D
Step 1: Use the rearranged simple interest formula to find the principal (P).
P = (SI × 100) / (R × T)
Step 2: Substitute the given values into the formula.
Given: Simple Interest (SI) = 1680, Rate (R) = 4%, Time (T) = 4 years.P = (1680 × 100) / (4 × 4)P = 168000 / 16
Step 3: Calculate the final sum.P = 10500.
Final Answer: Option 4
