An article is marked 35% above cost. If a profit of 20% is earned by selling the article, then the discount percent offered on the marked price of the article is:

Solution (By Examveda Team)

Let cost price = 100
\[\begin{array}{*{20}{c}} {{\text{Cost price}}}&{}&{{\text{Selling price}}}&{}&{{\text{Marked price}}} \\ {100}&:&{120}&:&{135} \end{array}\]
Discount % = $$\frac{{15}}{{135}}$$ × 100 = $$11\frac{1}{9}\% $$
