How to find the balance of suspense account

[Syndy]

The answer to the question Ive attached is Nil but I dont know why?

Your trial balance (before adjustment) is not balance as the total amount on the debit side is higher than that of credit side by $1,100. As a result, a supense account is opened (which is on credit side) in order to balance the "trial balance"

After taking all the adjustment entries, the suspense account will be eliminated (i.e. all the errors are corrected).
