A discount of 15\% on one article is the same as a discount of 20\% on another article. The costs of the two articles can be
(a)₹ 40, ₹ 20
(b)₹ 60, ₹ 40
(c)₹ 80, ₹ 60
(d)₹ 60, ₹ 40
Answer
Answer (as printed): C
Explanation
Let the costs of the two articles be $x$ and $y$. Then, $15 \%$ of $x=20 \%$ of $y \Rightarrow \frac{x}{y}=\frac{20}{15}=\frac{4}{3}$. So, $x$ and $y$ must be in the ratio of 4 : 3.
