The sales Ledger Control Account balance did not agree with the total from the schedule of receivables. Subsequent investigations revealed the following errors: i) Cash received of GHȼ600 had been credited to Kwaku Ansah’s account as GHȼ60. ii) The discount allowed column in the cash book had been overstated by GHȼ960. iii) A sales return of GHȼ3,200 from Adam Musah was correctly recorded in Adam Musah’s account but had been omitted from the total in the Sales Returns Journal. iv) A credit sale of GHȼ4,000 to Kofi Amosah was correctly recorded in the Sales Journal but no entry had been made in Kofi Amosah’s account. v) A cheque received from Naa Shikaa for GHȼ2,430 correctly processed through the books had subsequently been dishonored. No entries have yet been made to record this dishonored cheque. vi) A credit sale of GHȼ5,200 had been made to Kwaku Ansah but no entries have yet been made to record this transaction. vii) Cash received of GHȼ300 had been debited to Kofi Amosah’s account. viii) No contra entry had been made in Akua Afari’s account in the Sales Ledger in respect of purchases by Gyidi Ltd from Akua Afari for goods with a list price of GHȼ750 less an 8% trade discount.
