Welcome to the forums, @singhayushi0016.
It's not very clear what you're sayinghere.
If you publish the same article in more than one place, then that is duplicate content; one article is a duplicate of the other. Now, depending on how it's done, search engines may not penalise the second site for having duplicate content, but it's likely they will simply ignore one version when returning search results. After all, what use is it to the person searching to get multiple results pointing to the exact same article?
Please could you explain what you mean by this, as I don't understand it.
