A couple of questions in regards to the 2008 exam:
2.3.1 How do liabilities increase in the last transaction?
GST Clearing Liability is increased as a result of the sale of 5 beds.
2.3.2 I basically got most of this question wrong, cam someone explain how you do this.
The deposit (.2x10000=$2000) would have been recorded by the business as Prepaid Sales Revenue. The delivery of 15 beds (total selling price of $7500) results in the Prepaid Revenue being earned through the provision of stock (which was why the liability arose in the first place; the business had an obligation to provide stock). The General Journal is used to adjust the Prepaid Sales Revenue account.
Entry:
DR. Prepaid Sales Revenue 2000
CR. Sales Revenue 2000
The cost of sales relating to above adjustment can be recorded in the Sales Journal for convenience.
The debtor Great Southern Motors is yet to pay for the rest of the bed (2000/500=4, meaning they have paid for 4 beds, still owe for 11). The 11 beds must be treated as a normal credit sale.
Entry in Sales Journal:
Date, Debtor, Inv.No. as per normal
Cost of Sales = 4500 (4*300+11*300 OR 15*300)
Sales = 5500 (11*500, as 4 have already been paid for through the deposit)
GST = 750 (GST is calculated on the whole amount of $7500. Any form of deposit does NOT include GST - confirmed by Neville Box)
Total Debtors = 6250 (5500+750)
Q2.1.1
Yes, I'm pretty sure that assessment report is incorrect. As if 14300+650000=663300 LOL

Phew! Sorry for the long post, but I tried to explain it in depth.
