Yilandwe June 2015 Q1

Hi John Can you please provide some help with the working capital calculation in the question above... I understand that in Year 1 WC = 2112 (9600*22%) In Year 2 WC= 2422 (2112*1.147) as inflation drops to 14.7% In Year 3 WC = 2659 (2422*1.098) as inflation drops to 9.8% WC increased with inflation at the start of each next 3 years hence why I calculated wc as above for Year 1 and Year 2 but it is incorrect as I'm not getting same answer as examiner... In question Tramont December 2011 Q1 WC is calculated as above... the only difference being that inflation % does not change year on year... I know I'm missing some small detail.. I'd really appreciate your guidance here.. Many Thanks Annie
