Correct Answer - Option 3 : 3 years

**Given:**

P = Rs. 7500

R = 12%

A = Rs. 10,200

**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:**

Here, A = Rs. 10,200 P = Rs. 7500

⇒ I = 10200 – 7500

⇒ I = 2700

⇒ 2700 = 7500 × 12 × N/ 100

⇒ N = 2700 × 100/ (7500 × 12)

⇒ N = 3

**∴ After 3 years given sum of money will give Rs. 10,200 as amount**
