Let the cost price = 100.

A loss of 4% = 100 - (4% of 100) = 100-4 = 96.

Let x = the selling price.
Since the $4 loss occurs if the product is sold at 3/4 of the selling price, we get:
96 = (3/4)x
32 = (1/4)x
x = 128.

Profit at the selling price = (selling price) - (cost price) = 128-100 = 28.
Profit percentage = profit/cost = 28/100 = 28%.

The correct answer is B.

Let, three-fourths (3/4) of its selling price = 96
i.e. Selling Price = 96*(4/3) = 128

Also 96 = Cost price - 4% of cost price

i.e. 0.96*Cost price = 96

i.e. Cost price = 100

Profit or loss at actual SP = (SP - CP)*100/CP = [128-(100)]*100/(100) = 28% Profit

Answer: option B
