Question

If the loss incurred on selling an article is 7/20 of the cost price, then find the loss percentage.​

Answer 1

Answer: The loss percentage = 65%

Step-by-step explanation:

Let x be the cost price.

As per given,

Selling price = $\dfrac{7}{20}x$

Loss =Cost price - Selling price

$=x-\dfrac{7}{20}x\\\\=\dfrac{20-7}{20}x\\\\=\dfrac{13}{20}x$

The loss percent = $\dfrac{loss}{Cost\ price}\times100$

$=\dfrac{\dfrac{13}{20}x}{x}\times100\\\\=\dfrac{13}{20}\times100\\\\=13\times5\%\\\\=65\%$

Hence, the loss percentage = 65%
