Correct Answer - Option 4 : Rs. 8505

**Given**

Principal = Rs. 9,000

**Calculation**

Simple interest = (9000 × 5 × 1)/100

⇒ 450

Amount paid at the end of 1st year = Rs. 1350

Amount outstanding for second year = 9000 + 450 - 1350

⇒ Rs. 8100

Interest for second year = (8100 × 5 × 1)/100

⇒ Rs 405

Amount should be pay at the end of second year = 8100 + 405

⇒ Rs. 8505

**∴ Amount due at the end of second year is Rs. 8505**
