Performance Management

Good evening Sir. I know how to answer performance management questions quite well due to your lectures, I have a question though.
In BPP Revision kit, the performance management answers always seem to contradict the instructions given in the question. For example, a question can say give you answer to 2 decimal places and when you’re calculating for let’s say inventory days, you arrive at a number like 52.14. Isn’t that meant to be the answer, but in BPP the answer will be 52 instead of 52.14. Do decimal points matter in inventory, receivables and payable days?
Thank you.
