what will be the difference between simple interest and compound interest @ 10 % per annum on a sum of rs . 1000 after 3 years ?
"explanation : s . i . = rs . [ ( 1000 x 10 x 3 ) / 100 ] = rs . 300 c . i . = rs . [ 1000 x ( 1 + ( 10 / 100 ) ) 3 - 1000 ] = rs . 331 difference = rs . ( 331 - 300 ) = rs . 31 answer : e"
subtract(subtract(multiply(power(add(divide(10, const_100), const_1), 3), 1000), 1000), divide(multiply(3, multiply(10, 1000)), const_100))
