Correct Answer: INR 490


Solution : Amount for 3 years = INR 610
Amount for 4 years = INR 650
Simple interest = Amount – Principal
Simple interest for third year = 650 – 610 = INR 40
Total simple interest for 3 years = 40 × 3 = INR 120
Principal sum = 610 – 120 = INR 490
Hence, the correct answer is INR 490.
