- 11 articles for 10$ means 0.9090$ per article(cost price).
10 articles for 11$ means 1.1$ per article(selling price).
let x be the no of articles
therefore,63=x*sp-x*cp
x=63/(1.1-0.9090)
x=330. - 12 years agoHelpfull: Yes(2) No(0)
- Given that he purchases 11 articles for $10.

Given that he sells 10 articles for $11.
Hence, he sells 110 articles for $121.
Thus, by selling 110 articles he gains $21.
