I’m happy to share with you I got my Wordpress posts and pages from softaculous backup file.
After Reading the mentioned advice from @KangJL I understand that the importants of DATABASE files.
So I searched and got the SQL file from EXTRACTED SOFTACULOUS subfolder file named SOFTSQL.
But which was containing all the tables in single file but i need only Export the following tables (postmeta, post, termmeta, terms, term-relationships and term_taxonomy) and commentmeta and comments (without this tweak not worked for me )
I make the new exported sql file containing (postmeta, post, termmeta, terms, term-relationships ,term_taxonomy ,commentmeta and comments)
then i added prefix and import.
Finally Its Done !!!
I got my pages and Posts !!! 
THANKS FOR GIVING IDEA ABOUT THE TWEAK!!! 
THankyou aslo for the reply!!!
Love You!!
