In my application, i have uploaded PPT,PPTX files using paperclip gem. I have url like this
" Presentation.last.avatar.url" = "/system/presentations/avatars/000/000/006/original/example.ppt?1411994371"
Now i want to display those PPT, and PPtx files in my localhost web browser. please give me suggestions.. thanks

Assuming you mean that you want them to be embedded in the browser, I've solved this by uploading the them to Scribd in the background and then displaying the embedded widget. This is a great solution because turning a PPT file into clean HTML is hard (so let someone else work it out), and you do not have to pay for hosting or bandwidth for those files.
It's a lot nicer to do it this way than to force the user to have an Office plugin installed for their browser, which depending on their platform they may not have.
The Scribd_fu gem will work with Paperclip, or you could use the official RScribd gem and roll your own.
