Need help with first example in chap 3

Hi This was asked a few days ago bu someone else. the significance of the 25,000 is that there is 25,000 sitting in the revaluation reserve relating to the impaired asset. the remaining 10,000 should be debited to Profit or Loss but I appear to have missed it. It's in my mind to change /correct the error when I next review the notes over the Winter quiet period
