Bank Recon

Dear sir, if the question mentions that the bank balance is o/d, it should be a negative figure correct?

Question :

The cash book shows a bank balance of $5,675 overdrawn at 31 August 20X5. It is subsequently
discovered that a standing order for $125 has been entered twice, and that a dishonoured cheque for
$450 has been debited in the cash book instead of credited.
What is the correct bank balance?
A $5,100 overdrawn
B $6,000 overdrawn
C $6,250 overdrawn
D $6,450 overdrawn

Answer :

Balance b/d 5,675 o/d —— why isnt this (5,675)?
Less: standing order (125)
Add: dishonoured cheque (450 ? 2) 900
6,450 o/d

thank you sir and sorry for the disturbance 🙁
