if the simple interest on a sum of money for 2 years at 5 % per annum is rs . 58 , what is the compound interest on the same sum at the rate and for the same time ?
"explanation : sum = ( 58 * 100 ) / ( 2 * 5 ) = rs . 580 amount = [ 580 * ( 1 + 5 / 100 ) 2 ] = rs . 639.45 c . i . = ( 639.45 - 580 ) = rs . 59.45 answer : a"
subtract(add(add(divide(multiply(divide(58, multiply(divide(5, const_100), 2)), 5), const_100), divide(58, multiply(divide(5, const_100), 2))), divide(multiply(add(divide(multiply(divide(58, multiply(divide(5, const_100), 2)), 5), const_100), divide(58, multiply(divide(5, const_100), 2))), 5), const_100)), divide(58, multiply(divide(5, const_100), 2)))
