Correct Answer: $20\%$


Solution : Given that the ratio of the cost price and selling price of an article is 5 : 6.
Let the selling price be 6k and the cost price be 5k.
Profit = 6k – 5k = k
$\therefore$ Profit percentage $=\frac{\text{Selling price – Cost price}}{\text{Cost price}}×100=\frac{k}{5k}×100=20\%$
Hence, the correct answer is $20\%$.
