Question : 12 of 100

Marks: +1, -0

If the cost price of an article is 3/2 of its selling price, then the profit or loss percent is

33 $1/3$ %profit
33 $1/3$ %loss
33 $1/8$ %loss
33 $1/8$ %profit

Solution:

Let the cost price of the article be x.
Cost price of the article = 3/2 × (selling price of the article)
x = 3/2 × (selling price of the article)
Selling price of the article = 2x/3
Loss = cost price of the article - selling price of the article
= x – 2x/3 = x/3
Loss percentage = {Loss/ (cost price of the article)} × 100
= {(x/3)/x} × 100 = 100/3
∴Loss=33

1/3
