B Correct answer
Explanation

Selling price = 380, Loss = 20. Cost price = 380 + 20 = 400. Loss percent = (Loss / CP) * 100 = (20 / 400) * 100.

AI explanation

Using the formula for loss percentage, the calculation is (loss divided by cost price) multiplied by 100. The loss is given as Rs. 20 and the selling price is Rs. 380, so the cost price equals selling price plus loss, which is 380 + 20 = Rs. 400. Therefore, the correct expression to find the loss percent is $\displaystyle\frac{20}{400}\times 100$.
