<result>D</result>
the difference between the compound interest compounded annually and simple interest for 2 years at 20 % per annum is rs. 288. find the principal?
divide(288, subtract(power(add(divide(20, const_100), const_1), 2), add(multiply(divide(20, const_100), 2), const_1)))
"p = 288 ( 100 / 5 ) ^ 2 = > p = 7200 answer : d"
