Try the below:
create table #temp (sdate datetime,location char(1),Item varchar(20))
insert into #temp values('1 jan 14','A','Apple')
insert into #temp values('2 jan 14','A','Apple')
insert into #temp values('3 jan 14','B','Apple')
insert into #temp values('4 jan 14','B','Apple')
insert into #temp values('1 jan 14','A','Orange')
insert into #temp values('2 jan 14','A','Orange')
insert into #temp values('3 jan 14','B','Orange')
insert into #temp values('4 jan 14','B','Orange')
;With cte as
Select * , Row_Number()Over(partition by location, item order by sdate desc) Rn
From #Temp
Select * From cte Where rn=1 Order by Item asc,location asc
drop table #temp
