How to Remove word "content" from URL in Drupal 7

I got this simple problem when i enabled Clean url and installed path auto Module.

when i open my article i was getting the below url with word " Content" in it.
http://naiwik.com/content/best-drupal-7-modules-new-site

instead i wanted the url to look like below

http://naiwik.com/best-drupal-7-modules-new-site

All you have to do is Admin -> Configuration -> SEARCH AND METADATA -> URL aliases -> Patterns -> Content path
