Hi ,
Maybe you have mistaken in the concept.
COGAS (Cost of Goods available for Sale) is not same as COGS (Cost of Goods Sold).
COGAS is Beginning Inventory + Purchases + Direct labour + Overheads = Cost of Goods available for sale during the year.
From COGAS we deduct the ending Inventory to arrive at COGS ; COGAS - Closing Inventory = COGS.
In the question , it is given ; COGAS as $ 136,000/- not COGS . Hence as per the above concept to arrive at COGS we need to deduct / subtract Closing Inventory from COGAS ; $ 136,000 - $ 13,000 = $ 123,000/- as COGS.
As mentioned in the question the manufacturing overhead is underapplied by $ 5,000/- and it is to be allocated on prorata basis.
So, 123,000 + (5,000 / 156,000 x 123,000) = 123,000 + 3,942 = $ 126,942
Hope it is clear.
