Hint: making use of the formula of compound interest. In the given question we are provided Note: For per annum compound interest is calculated for the whole year. But if in a question it was asked for half-yearly too we have to take a time period of 6 months. The calculation should be done properly. Compound interest is the total annual interest earned over a set period of time on a loaned principal. The amount of money remaining at the end is called the amount. The entire compound interest earned is the sum of the initial principal and the total compound interest earned. It is given that Principal (P) = ₹ 8000 Rate of interest (r) = 10% p.a. Period (n) = 4 years We know that Amount = \mathrm{P}(1+\mathrm{r} / 100)^{\mathrm{n}} Substituting the values = 8000(1+10 / 100)^{4} By further calculation = 8000 × 11/10 × 11/10 × 11/10 × 11/10 = ₹ 11712.80 Here CI = A – P Substituting the values = 11712.80 – 8000 = ₹ 3712.80 Find the amount and the compound interest on Rs 8000 for \[1\frac{1}{2}\] years at 10% per annum, compounded half-yearly.
