what will be the difference between simple interest and compound interest @ 10 % per annum on a sum of rs . 1000 after 4 years ?
solution s . i . = rs ( 1000 x 10 x 4 / 100 ) = rs . 400 . c . i . = rs . [ 1000 x ( 1 x 10 / 100 ) 4 - 1000 ] = rs . 464.10 ∴ difference = rs . ( 464.10 - 400 ) = rs . 64.10 answer d
subtract(subtract(multiply(power(add(divide(10, const_100), const_1), const_4), 1000), 1000), divide(multiply(4, multiply(10, 1000)), const_100))
