Hedged foreign assets interest, currency, expected, 2010

AnalystForum

Question 54 on the 2010 CFA mock, I missed it. I did the R(u)= R(asset)+ r(FC) then R(H)=R(u)-h(R(forward))

For expected currency return I used interest rates to solve for future spots.

In this case they just did R(H)=R(asset)+ r(forward)

Can someone simplify when to do each scenario?
