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