Double entry bookkeeping

Dear Sir,
I had a question about question 4.1 and 4.2 of BPP F3 revision kit.
May 1, Sold $160 of goods to P Dixon on Credit
May 1. WIthdrew $50 from the business
May 2. Purchased goods from A Clarke on Credit for $380 less 15% trade discount
May 2. Repaid a dept of $120 owing to R Hill, taking advantage of a 10% settlement discount. The payment was by cheque
May 3. Sold $45 of goods for cash
May 4. Sold $80 of gods to M Maguire on credit, offering a 12.5% discount If payment made within 7 days. Marshall expects Maguire to take up the discount
May 4, Paid a phone bill of $210
May 4. Received a cheques from H Larkin for $180
May 5. Sold $304 of goods to M Donald on credit.
May 6 Recieve a Cheque from D Randle for $482
May 6 Purchased $100 of goods from G Perkins

4.1. What is the total of the transactions recorded in the receivables ledger?
The answer given in the book is 534$. But I don’t understand why they didn’t account for the transaction on May 6. I think that receipt a cheque of 482$ will result in a credit entry in the receivables ledger?

4.2. What is the total of the transactions recorded in the payables ledger?
The answer given in the book is823$. But I don’t understand why they didn’t account for the transaction on May 2. I think that a payment of 120$ will result in the debit entry in the payables account?

I look forward to your explanation.
Hope you have a great day!!
