A. 6 years
B. 5 years✓ Correct Answer
C. 12 years
D. 10 years
💡 Solution & Explanation
Interest for one year = 12% of ₹17,000 = ₹2,040. The total interest is ₹10,200, so the time = 10,200 ÷ 2,040 = 5 years. Using the formula: time = interest × 100 ÷ (principal × rate) = 10,200 × 100 ÷ (17,000 × 12) = 5.
