In how many years will ₹25,000 earn a simple interest of ₹18,000 at 12% per year?
A. 9 years
B. 12 years
C. 6 years✓ Correct Answer
D. 7 years
💡 Solution & Explanation
Interest for one year = 12% of ₹25,000 = ₹3,000. The total interest is ₹18,000, so the time = 18,000 ÷ 3,000 = 6 years. Using the formula: time = interest × 100 ÷ (principal × rate) = 18,000 × 100 ÷ (25,000 × 12) = 6.
