Hi can someone please help me answer the questions (a and b) in the pictures attached. All information is provided within the pictures. Thank you

You are the bookkeeper of Timothy Stores, a gift shop. The entity uses the perpetual method for accounting for inventory. The Accounts Payable Account reflected a balance of R61 417 which includes three creditors as follows: The supplier Griffin Traders allows a 10\% settlement discount if payment is made within 30 days and Gama Traders allows a trade discount of 8% on all goods purchased. It is probable that Timothy Stores will pay in time to receive the discount. The balances on the statements received from the supplier reflected the following balances: The following discrepancies were noted between the ledgers and statements: - Griffin Traders: o An invoice for inventory purchased for R3 400 was omitted from the statement. o Inventory purchased on credit from Griffin Traders, R7 200, was incorrectly posted to the account of Gama Traders in the accounts payable ledger. o The balance owed to Griffin Traders at the end of May 2019 was R8 800. This had not yet been paid by Timothy Stores by the end of June 2019. Interest was charged on the statement but no entry was recorded in the journals of Timothy Stores. o During the month Griffin Traders' owner purchased goods from Timothy Stores for R800 and agreed to set-off the amount against their debt. The bookkeeper omitted this entry. o Goods of R1 350 returned to Griffin Traders were incorrectly treated as a credit purchase in the journal and posted accordingly. o The amount of R2 100 reflected as a refund in the Accounts Payable Account was in fact received from a debtor, T Barack, whose account had previously been written off as a bad debt. o An amount of R80 in the Purchase Returns journal for inventory returned was reflected as an invoice of R800 on the statement. The statement is incorrect. o The statement showed an invoice recorded at a gross amount of R2 300 . o A credit note was entered on the statement twice; the amount of the credit note was R400. o A sale to A Barack, a debtor, was incorrectly recorded as a purchase in the purchases journal and posted to the account of Griffin Traders. The sale amount was R4 800 and the cost of sales amounted to R2 400 . - Gama Traders o Inventory purchased on credit from A Barack, R7 200, was incorrectly posted to the account of Gama Traders in the accounts payable ledger. You are required to: a) Prepare the accounts payable ledgers of Griffin Traders and Gama Traders as it would appear in the accounts payable ledger of Timothy Stores. b) Prepare the remittance advice that would accompany the cheque to Griffin Traders at 30 June 2019
