Nihar,
You can write a pl/sql block to achieve this
CREATE TABLE new_table (table_name VARCHAR2 (30), COUNT     NUMBER);
DECLARE
   CURSOR mcur
   IS
      SELECT   table_name
        FROM   user_tables
       WHERE   table_name IN ('A', 'B', 'C');
   v_sql   VARCHAR2 (100);
   v_count number;
BEGIN
   FOR x IN mcur
   LOOP
      v_sql := 'select count(*) from ' || x.table_name;
      EXECUTE IMMEDIATE v_sql INTO   v_count;
      INSERT INTO new_table
        VALUES   (x.table_name, v_count);
   END LOOP;
   COMMIT;
END;
select * from new_table;Regards
