Correct Answer - Option 3 : Rs. 1050

**Given:**

N = 4.5 yrs

R = 10%

I = Rs. 2250

**Formula used:**

I = P × R × N/ 100

A = P × (1 + (R/ 100))^{N}

A = P + I

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

**Calculation:**

2250 = P × 10 × 4.5/ 100

⇒ P = 2250 × 100/ 45

⇒ P = Rs. 5000

Now, finding compound interest

A = 5000 × (1 + (10/ 100))^{2}

⇒ A = 5000 × 11 × 11/ 100

⇒ A = Rs. 6050

⇒ I = 6050 – 5000

**∴ Compound interest = Rs. 1050**
