the true discount on a bill due 9 months hence at 16 % per annum is rs . 189 . the amount of the bill is :
"solution 32.5 let p . w . be rs . x . then , s . i . on rs . x at 16 % for 9 months = rs . 189 . ∴ x 16 x 9 / 12 x 1 / 100 = 189 or x = 1575 . ∴ p . w . = rs . 1575 . ∴ sum due = p . w . + t . d . = rs . ( 1575 + 189 ) = rs . 1764 . answer b"
add(divide(189, divide(multiply(divide(9, multiply(const_4, const_3)), 16), const_100)), 189)
