Answer / krishna murari chaubey

create table Employee(empId int,age int)
create table Area(empId int,Region varchar(20))

Use Inner Join

select e.empid,e.age,a.region from Employee e inner join
area a on e.empid=a.empid and e.age in
(select max(age) from Employee)

OR


select empid,region from area where empid in
(select empid from Employee where age
in(select max(age) from Employee))
