what will be the difference between simple and compound interest @ 25 % per annum on a sum of $ 3600 after 2 years ?
"s . i . = 3600 * 25 * 2 / 100 = $ 1800 c . i . = 3600 * ( 1 + 25 / 100 ) ^ 2 - 3600 = $ 2025 difference = 2025 - 1800 = $ 225 answer is c"
subtract(subtract(multiply(3600, power(add(divide(25, const_100), const_1), 2)), 3600), multiply(multiply(3600, divide(25, const_100)), 2))
