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%

Explanation:

Let x be the cost price.

As per given,

Selling price =
`(7)/(20)x`

Loss =Cost price - Selling price

`=x-(7)/(20)x\\\\=(20-7)/(20)x\\\\=(13)/(20)x`

The loss percent =
`(loss)/(Cost\ price)*100`

`=((13)/(20)x)/(x)*100\\\\=(13)/(20)*100\\\\=13*5\%\\\\=65\%`

Hence, the loss percentage = 65%
