what is the compound interest paid on a sum of rs . 700 for the period of 2 years at 10 % per annum .
"solution = interest % for 1 st year = 10 interest % for 2 nd year = 10 + 10 % of 10 = 10 + 10 * 10 / 100 = 11 total % of interest = 10 + 11 = 21 total interest = 21 % 700 = 700 * ( 21 / 100 ) = 147 answer c"
subtract(multiply(700, power(add(const_1, divide(10, const_100)), 2)), 700)
