I think you need to show the detail context of the question. Return % here is two general. Is it real interest rate or nornimal interest rate. The former one is without inflation premium while the latter one does include.
Anyway,你引的书上给的算法没错,关键是inflation is implied in BOTH rates. 所以risk premium就是不涉及inflation。
直观理解,equity和bond的yield中都体现了inflation,即它俩相同的components。但risk premium体现的是它俩的差异。
