Question
Suresh placed Rs. 6,000 into an investment plan that
accrues compound interest at an annual rate of 15%, compounded yearly. Calculate 80% of the compound interest earned after two years.Solution
Compound interest received by Suresh = 6000 × {1 + (15/100)}2 – 6000 = 6000 × 1.152 – 6000 = 7935 – 6000 = Rs. 1,935 So, 80% of the compound interest received = 1935 × 0.8 = Rs. 1,548
