Answer:
D. 0%
Explanation:
The percentage of profit at which one of the products are sold = 30%
The percentage loss at which the other product are sold = 30%
Let x represent the prices of each of the products, we have;
The profit from the sale of the first product = 30% of x = 0.3·x
The loss from the sale of the second product = -30% of x = -0.3·x
The total gain or loss = Profit + Loss = 0.3·x + (- 0.3·x) = 0
Therefore, there is no net loss
The total loss incurred = 0%.
