Allowance on receivables

At 1 July 2005 a company’s allowance for receivables was $48,000.
At 30 June 2006, trade receivables amounted to $838,000. It was decided to
write off $72,000 of these debts and adjust the allowance for receivables to
$60,000.
What are the final amounts for inclusion in the company’s balance sheet at
30 June 2006?
Trade Allowance for Net
receivables receivables balance
$ $ $
A 838,000 60,000 778,000
B 766,000 60,000 706,000
C 766,000 108,000 658,000
D 838,000 108,000 730,000

I am certain the receivables is $766,000..
However, for the allowance for receivables, I am not too certain.. is it 60,000?
Thx..
