Hello
It's always usefull to provide some test data and create table scripts etc, but does this do what you're after?
create table dt_test_t1
(item_code                     varchar2(3),
item_desc                    varchar2(10),
item_province               varchar2(20),
item_selling_price          number(3)
) tablespace av_datas;
INSERT INTO dt_test_t1 VALUES('ABC','Item1','Province1',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item1','Province2',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item1','Province2',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item2','Province1',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item2','Province1',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item2','Province1',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item3','Province2',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item3','Province2',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item3','Province2',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item4','Province1',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item4','Province1',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item4','Province2',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item5','Province2',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item5','Province1',10);
INSERT INTO dt_test_t1 VALUES('ABC','Item5','Province2',10);
