If the selling price of an article is $$\frac{3}{4}$$ times its cost price, the profit/loss percent is:

If the selling price of an article is $$\frac{3}{4}$$ times its cost price.

Let's assume the cost price of the article is 4y.

the selling price of article = $$\frac{3}{4}\times4y$$ = 3y

As we know that the cost price of the article is more than its selling price. So there will be a loss.

loss percent = $$\frac{\left(\cos t\ price\ -\ selling\ price\right)}{\cos t\ price}\times100$$

= $$\frac{\left(4y\ -\ 3y\right)}{4y}\times100$$

= $$\frac{y}{4y}\times100$$

= 25%
