Solution
The ratio of the cost price (CP) to the selling price (SP) is given as 20:21. This means that if the cost price is 20 units, then the selling price is 21 units.
The gain is calculated as the difference between the selling price and the cost price. In this case, the gain would be 21 units (SP) - 20 units (CP) = 1 unit.
The gain percentage is calculated as (Gain/CP)*100. Substituting the given values, we get (1/20)*100 = 5%.
So, the gain percent on the article is 5%. Therefore, the correct answer from the given options is 5.
