try this

select *
  from
  (
    select
        sal
          ,dense_rank() over (order by sal desc) ranking
    from   table
  )
  where ranking = 4 -- Replace 4 with any value of N

Answer 5

select * FROM (
select EmployeeID, Salary
, dense_rank() over (order by Salary DESC) ranking
from Employee

WHERE ranking = N;

dense_rank() is used for the salary has to be same.So it give the proper output instead of using rank().

                FROM emp
            )
    WHERE NRANK = 4
