Answer 1

h4. # Database should be 10g. If version is below 10g query need to be modified as per string format.
h4. # Split string into two parts by '/'. First part contain brand + packet(1), Second part contain packet(2) + amount + total
h4. # Your brand name can be of any length.
String Format* : <Brand Name><space><packet(1)>/<packet(2)><space><amount><space><total>
SELECT name,
       REGEXP_SUBSTR(first_part,'.+[[:space:]]',1,1) brand,
       REGEXP_SUBSTR(first_part,'[^[:space:]]+/',1,1) || REGEXP_SUBSTR(second_part,'[^[:space:]]+[[:space:]]',1,1) packet,
       REGEXP_SUBSTR(second_part,'[^[:space:]]+[[:space:]]',1,2) amount,
       REGEXP_SUBSTR(second_part,'[^[:space:]]+$',1) total
FROM
  (SELECT trim(name) name,
          trim(substr(name,1, instr(name,'/'))) first_part,
          trim(substr(name,instr(name,'/')+1)) second_part
   FROM test )
