Question

A discount of $15\%$ on one article is the same as a discount of $20\%$ on another article. Find the ratio of the cost price of the two articles.

• A. 15:17
• B. 13:15
• C. 16:17
• D. 12:17

Answer 1

The correct option is C

16:17

Let the costs of the two articles be x and y. Then, 85% of x = 80% of y

$\frac{x}{y}=\frac{80}{85}=\frac{16}{17}$.

So, x and y must be in the ratio of 16:17.
