Hi Mankrish:
Unless until you delete the table using 'DROP TABLE SECTION PURGE' , the dropped table will go and resides in the recycle bin with system generated name. When you issue 'select table_name from user_tables' that table will also list in the resultset.
Issue 'PURGE RECYCLEBIN' from your SQL prompt then issue the same command 'select table_name from user_tables' then you will find the difference.
Thank you,
