Simple & Compound Interest question 11
Kavya invests ₹12,000, part at 8% and the rest at 10% simple interest per annum. Her total interest after 1 year is ₹1,080. How much did she invest at 8%?
- ₹5,000
- ₹7,000
- ₹6,000
- ₹4,000
Answer and explanation
Answer: C. ₹6,000
Explanation: If all ₹12,000 earned 10%, interest would be ₹1,200. Each rupee moved to 8% reduces it by 0.02, so x × 0.02 = 120 and x = ₹6,000.
