find the compound interest on $ 50000 in 2 years at 4 % per annum , the interest being compounded half - yearly ?
principle = $ 50000 rate = 2 % half yearly = 4 half years amount = 50000 * ( 1 + 2 / 100 ) ^ 4 = 50000 * 51 / 50 * 51 / 50 * 51 / 50 * 51 / 50 = $ 54121.60 c . i . = 54121.60 - 50000 = $ 4121.60 answer is b
subtract(multiply(power(add(divide(divide(4, const_100), 2), const_1), 4), 50000), 50000)
