the banker ' s gain of a certain sum due 2 years hence at 10 % per annum is rs . 24 . the present worth is
solution t . d = ( b . g x 100 / rate x time ) = rs . ( 24 x 100 / 10 x 2 ) = rs . 120 . p . w = ( 100 x t . d / rate x time ) = rs . ( 100 x 120 / 10 x 2 ) = rs . 600 . answer c
divide(multiply(const_100, divide(multiply(24, const_100), multiply(2, 10))), multiply(2, 10))
