Ordan received a statement from one of its suppliers, Alta, showing a balance due of $3,980. The amount due according to the payables ledger account of Alta in Ordan’s records was only $230. Comparison of the statement and the ledger account revealed the following differences: 1 A cheque sent by Ordan for $270 has not been allowed for in Alta’s statement. 2 Alta has not allowed for goods returned by Ordan $180. 3 Ordan made a contra entry, reducing the amount due to Alta by $3,200, for a balance due from Alta in Ordan’s receivables ledger. No such entry has been made in Alta’s records. What difference remains between the two companies’ records after adjusting for these items?
