The formula for compound interest is P 1 rn nt where P is the initial principal balance r is the interest rate n is the number of times interest is compounded per time period and t is the number of time periods. If the Interest is Compounded Annually then Formula to Calculate the Compound Interest is given by. There are other types of questions that can be answered using the compound interest formula.
The compound interest formula is given below.
Rate of Compound Interest for Successive Years is different ie. 160000 Annual rate of interest R 10 Rate of interest for a half year 10 2 5 Time n 2 years 4 half years Then the amount with the compound interest is given by A P 1 R 100 n 160000 1 5 100 4 160000 100 5 100 4 160000 105 100 4 160000 21 20 21 20 21 20 21 20 21 21 21 21 Rs 194481 Therefore compound interest amount - principal Rs 194481-160000 Rs 34481. Given details are Principal p Rs 160000. Click on a link below Serial Order Wise to study from the NCERT Book - like if you want a particular exercise question.
