Hope you are using Sql Server 2008(other wise the insert statement in my query won’t work). Try this one.
From the required out put, i guess you need all the values from table2 and there corresponding Single(Column name in table 1) value.

DECLARE @tempTable1 TABLE (ID1 INT,Name VARCHAR(10),ID2 INT,Single INT)
DECLARE @tempTable2 TABLE (ID1 INT,Name VARCHAR(10),ID2 INT,Monthly INT)

    INSERT INTO @tempTable1 VALUES
    (1            ,'ABC'         ,1            ,100),
    (2            ,'DEF'         ,1            ,200)

INSERT INTO @tempTable2 VALUES
(3            ,'PQR'         ,2            ,500  ),
(4            ,'LMN'         ,2            ,600  ),
(1            ,'ABC'         ,2            ,700  ),
(2            ,'DEF'         ,2            ,800 );
SELECT
                T2.ID1
                ,T2.Name
                ,T2.ID2
                ,T1.Single
                ,T2.Monthly

FROM            @tempTable2 T2
LEFT OUTER JOIN @tempTable1 T1
ON              T2.ID1 = T1.ID1
ORDER BY        T2.ID1
