So we can work the cost of the closing balance in this question using the table below

Date   Description         Qty   unit ($)                    Value

Sept 1     Bal b/f           20    ×    20        =                 400

       4     Sales           ( 10)  ×     20                           200

                                    10                                      200

        10   Purchase      30  ×    25        =                  750

                                   40                                       950

        17    Sales           ( 20)    Wk 1      =               ( 450)

                                     20                                      500

       30    Purchases     10  ×   30.      =                    300

Closing inventory       30                                       800
