You will have to first take the count and pct in a subquery then use max+decode function to summarize both of them in the required fashion Check if the below query helps:

SELECT Max(Decode(i.place,'Kitchen',cnt)) AS "Kitchecn"
     , Max(Decode(i.place,'Kitchen',pct)) AS "Pct"
     , Max(Decode(i.place,'Washroom',cnt)) AS "Washroom"
     , Max(Decode(i.place,'Washroom',pct)) AS "Pct"
     , Max(Decode(i.place,'Rooftop',cnt)) AS "Rooftop"
     , Max(Decode(i.place,'Rooftop',pct)) AS "Pct"
     , Max(Decode(i.place,'Garden',cnt)) AS "Garden"
     , Max(Decode(i.place,'Garden',pct)) AS "Pct"
  FROM (SELECT i.place
             , Count(pim.injury_id) AS cnt
             , (Count(pim.injury_id)*100/(SELECT Count(*) FROM person_injuryPlace_map)) AS pct 
          FROM person_injuryPlace_map pim
         INNER JOIN injury_place i ON i.id = pim.injury_id
         GROUP BY i.place)
