Hi s_ha_dum,
Thanks a lot for prompt help, my apologies for delay at my end due to net connectivity issue.
Url of the post is http://localhost/mytoursite/tourpackage/agra/
where tour package is custom post type name and agra is title of my post.
One thing which I noted while executing wordpress in debug mode that the post type returned by get_post_type function for this is post while in database post table it shows post type as tourpackage the one I defined in slug.
