Sales Quantity Contribution Variance

Please - do not simply ask full questions and expect a full answer. The ACCA publishes answers to the exams and therefore you should ask which part of the answer you do not understand. There is no point in me simply typing out the examiners answer :-) There are free lectures working through the whole of the June 2015 exam and explaining the answers, on this website. You can find them by going to the main Paper F5 page and following the link to "Revision Kit Live".

I am pleased that you are now clear about how to answer it :-)
