    Solution:

    Concept- C.P. is referred to as the cost price of a product.
    S.P. stands for the selling price of a product.
    If S.P. is greater than C.P., then the difference of S.P. and C.P. is known as “Profit”.
    The margin of profit on C.P. is known as the “Gain Percentage” or “Profit Percentage”.
    Profit = S.P. – C.P. (in case, S.P. > C.P.)
    Gain Percentage = Given,
    By selling 20 articles, a person gains or makes a profit amount which is equal to the C.P. of 5 articles.
    Let us consider the C.P. of an Article to be “c”.
    And, the S.P. of an article to be “s”.
    Then, C.P. of 20 articles = 20c
    And, S.P. of 20 articles = 20s
    Therefore, Profit = (20s- 20c)
    But, Profit also = 5c
    Therefore, Profit Percentage = Profit Percentage = Profit Percentage = Profit Percentage = 25%
    Hence, the correct answer is 2) 25%.
