why isn’t the expected portfolio return of 4% added as a cash inflow for the first year?

FYI, 2006 #1 has a similar concept, but this time the portfolio return is counted as a cash inflow

The consensus is to let go the return calculation. :-p Return calculation for a induvidual comes for a total of 8 (2= Formulate and 6=Calculate). Those 6 marks are nothing compared to the other 360-6 marks at stake. PS: I have done good amount of exams and never got a single return calculation correct. There is that one curve ball that you forget to account and the retuns is off!
