Answer:
C. $11,498.73.
Explanation:
Solving this question, we will have to make use of this formula:
The Adjusted Bank Balance = Unadjusted Balance as per Bank Statement as at Oct 31, 2015 - Checks Outstanding
= $12,956.73 - $2,112.19 = $10,844.54
Now,
Before the adjustment on the 31st of October, 2015,
The Cash account Balance = Adjusted Bank Balance + insufficient funds checks
= $10,844.54 - $654.19 = $11,498.73
Hence third option in the question is the correct answer.
