Correct Answer - Option 2 : Rs. 8600

**Given:**

I = Rs. 3870

N = 5

R = 9%

**Formula used:**

I = P × R × N/ 100

A = P + I

Where, P = Principal amount, R = Rate of interest, N = number of years and I = Simple interest

**Calculation:**

3870 = P × 9 × 5/ 100

⇒ P = 3870 × 100/ 45

⇒ P = 86 × 100

**∴ P = Rs. 8600**
