if the simple interest on a sum of money for 4 years at 8 % per annum is rs . 560 , what is the compound interest on the same sum at the rate and for the same time ?
"sum = ( 50 * 100 ) / ( 2 * 5 ) = rs . 1 , 750.00 c . i . on rs . 1 , 750.00 for 4 years at 8 % = rs . 2 , 380.86 . = rs . 2 , 380.86 - 1 , 750.00 = rs . 630.86 answer : d"
subtract(add(add(divide(multiply(divide(560, multiply(divide(8, const_100), const_2.0)), 8), const_100), divide(560, multiply(divide(8, const_100), 4))), divide(multiply(add(divide(multiply(divide(560, multiply(divide(8, const_100), 4)), 8), const_100), divide(560, multiply(divide(8, const_100), 4))), 8), const_100)), divide(560, multiply(divide(8, const_100), 4)))
