subtract(multiply(divide(subtract(const_100, 15), const_100), multiply(add(const_100, 20), divide(add(const_100, 25), const_100))), const_100)
assume the total price = 100 x price after 20 % markup = 120 x price after 25 % further markup = 1.25 * 120 x = 150 x price after the discount = 0.85 * 150 x = 127.5 x hence total profit = 27.5 % option a
