Answer 1

You can do:
SELECT *
FROM (SELECT name, Max(Price) -- to get the max price
FROM Items
GROUP BY name -- the column "item" is in the select
-- that's why it's put in GROUP BY
ORDER BY 2 DESC) -- Order by Maximum to Minimum
WHERE ROWNUM <= 10 -- ROWNUM is a virtual column, that count
-- the return records. So, only it musts
-- to get records when rownum has values
-- between 1 to 10.
