a trader sold an item at a loss of 18 % . if he had increased the price by $ 25 he would have made a gain of 5 % . what is the cost price of the item ?
let c . p . be $ x then 105 % of x - 82 % of x = 100 23 % of x = 100 23 / 100 * x = 100 23 x = 10000 x = 434.78 answer is d
divide(multiply(25, const_100), multiply(subtract(add(const_1, divide(5, const_100)), subtract(const_1, divide(18, const_100))), const_100))
