(a) Because it gives junior staff training in comparing records.

(b) Because there are usually many thousands of cash receipts in a year.

(c) Because you can’t test for existence unless you compare in both directions.

(d) Because the first provides evidence about the completeness of entries in the cash receipts transaction file and the second provides evidence about the existence of cash receipts transaction file entries.
