The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is
A
18
B
16
C
15
D
25
Correct Option:
B
Explanation
Let the cost price of one article be C. With a 25% profit, the selling price per article is 1.25C. Given 20C = x(1.25C). Cancelling C gives 20 = 1.25x, so x = 20/1.25 = 16. Therefore the selling price of 16 articles equals the cost price of 20 articles.
