PLEASE HELP ME TO SOLVE

Answer 1

 declare @id int
 select @id=empid from inserted
 insert into audit values ('new employee is inserted with id=' + CAST(@id as nvarchar(5))+'is added at'+CAST(GETDATE() as nvarchar(20)))
This code will not properly handle a multi-row insert.  I suggest an approach like the example below instead of scalar variables.  Also, I suggest you just store the normalized data in the audit table (id, action, timestamp) instead of the
formatted string.  That will facilitate subsequent queries and reporting on the data.
ALTER TRIGGER tr_employee1_insert
ON dbo.Employee1 FOR INSERT
AS
INSERT INTO dbo.audit (empid, auditdata)
SELECT
id
, 'new employee is inserted with id=' + CAST(id as nvarchar(5)) + 'is added at ' + CAST(GETDATE() as nvarchar(20))
FROM inserted;
