Answer:
13720
Step-by-step explanation:
The difference between lines 5 and line 6 is 13720 (49980 - 36260)
Which means that after reconciliation in the accounting balance 13720 are missing.
Then we must find the item that adds 13720.
This may occur due to omission or bad registration of outstanding deposits or credits (which means a higher balance) or the amount in the accounts of outstanding checks or debits may have been doubled or bad recorded (since these accounts subtract in the reconciliation)
