- Given: The cost price of y articles equals the selling price of z articles.

- The ratio y:z is 5:4.

- This means: CP of 5 articles = SP of 4 articles.

- Let's assume CP of one article = $1.

- Then, CP of 5 articles = $5.

- Hence, SP of 4 articles = $5.

- So, SP of 1 article = $5/4 = $1.25.

- Profit per article = SP - CP = $1.25 - $1 = $0.25.

- Profit percentage = (Profit per article / CP) x 100 = ($0.25 / $1) x 100 = 25%.

- Correct Answer: 25%
