Question

if the ratio of cost price and selling price of an article 5:4,what is the percentage of loss?

Answer 1

let the cost price be 5x
let the selling price be 4x
loss = l/cp *100

loss = x/5x *100

let loss be  l

l *5x/x = 100

Answer 2

Answer:

Loss Percentage = 20%

Step-by-step explanation:

The ratio of cost of price and selling price of an article is 5 : 4

Let the cost price of an article be 5x and the selling price of an article be 4x

We need to find the loss percentage of the article.

Now, Loss = Cost price - Selling price

⇒ Loss = 5x - 4x

⇒ Loss = x

Now, Loss percentage = x/5x × 100

                                       = 1/5 × 100

                                       = 20%

Thus, Loss Percentage = 20%
