Payables T/O

CFA Level I
#1

Isnt the Payables T/O Ratio = Purchases/Avg Payables ??? I have come across 2 Qbank questions that are using CoGS in the numerator… Which is proper?

#2

used to be COGS before - CFAI changed it around to Purchases / Payables Schweser hasn’t gotten around to changing it around yet.
