Ratio translation difference (for receivables turnover) under temporal method

The CFA Institute text in Reading 18, EOC #19’s answer states that revenues and receivables (monetary asset) would be the same if translated under either accounting method.

I thought that revenues were multiplied by the average rate and receivables by the current rate. Wouldn’t this change the receivables turnover ratio since they are being translated by different exchange rates?

Both of the methods are using average rate for translation of revenues and current rate for translation of accounts receivable. Hence, both methods result to the same receivables turnover.
