a trader bought a car at 5 % discount on its original price . he sold it at a 60 % increase on the price he bought it . what percent of profit did he make on the original price ?
original price = 100 cp = 95 s = 95 * ( 160 / 100 ) = 152 100 - 152 = 52 % answer : c
multiply(subtract(divide(divide(multiply(subtract(const_100, 5), add(const_100, 60)), const_100), const_100), const_1), const_100)
