Consolidations

Why are you attempting a question for which you do not have an answer? You should be using a Revision Kit from one of the ACCA Approved Publishers - they have answers and workings :-) The consolidated retained earnings are all of Dickson's retained earnings, plus 80% of the post-acquisition retained earnings of Sherry. (The revaluations do no affect the retained earnings but affect the revaluation reserve.) This is all explained in my free lectures on consolidations. The lectures are a complete free course for Paper FA and cover everything needed to be able to pass the exam well.
