How to Find nth Salary and his id from a table in SQL server

I am writhing a query that will be helpful in finding nth salary and his id of that record.

so its very simple and very understandable.......

select ID ,salary from testing where salary in(select MIN(salary) from testing where
salary in (select top 4 salary from testing   order by salary desc))

and then can fetch id ,salary of the table from the sub query result as u seeing in query.
