Answer:
50,000 overstated.
Step-by-step explanation:
As the ending inventory is overstated by 50,000 we can conclude the implications using the inventory identity:
Beginning + Purchase = COGS + Ending
As the left side will be the correct display they will have no error.
Therefore the COGS will compensate the mistake in the ending ivnentory
0 = COGS + 50,000
COGS = -50,000
The COGS are 50,000 lower than it should be therefore the gross profit is overstated as
Sales - COGS = Gross Profit
0 - (-50,000) = Gross Profit
+ 50,000 = Gross Profit
This also makes the operating income which, derives from gross profit to be overstated as well.
