1. a bad debt that was previouly written off is now re-instated -> increase bad debt recovered by 50 -> cr 50 in bad debt recov
2. if bad debt is recovered then ur debtors increase, hence dr wlee 50
3. error that they debited bad debt -> so undo it -> credit bad debt 50
4. they recieved 50 -> assets go up -> cash dr 50
5. if debtor pays, u credit his a/c -> cr wlee 50 BUT This is alredi done!
