Ah! Yes, it means the investment return isn't relevant in the solution.
(1) You are doing the right calculation
(11856/10000)^(1/5) -1 = 3.4%
So, 5% - 3.4% = 1.6%
(or 1.536% if I'd have kept some more decimal places!)
Note that the same calculation for Fund A gives 1.58%, so the question is simply giving a "round" number.
(2) If you compare fund values over time for an investment of £30,000
t Fund A Fund B
1 £30,405 £30,167
2 £31,606 £31,517
3 £32,855 £32,928
4 £34,153 £34,401
5 £35,502 £35,940
So, fund A is better, unless you are investing for at least 3 years, when B is better.
