This question builds on part (ii) where the solution to the prospective surrender value at 31 Dec 2020 is:
SV = SA*Abar + expenses*adue - premium*adue
SV = 100000*0.839868 +. 100*8.166749 - 6292*8.166749
SV = 33,418
However, Q4 (iii) then says expenses over 2021 were 30% higher what the surrender value at 31 Dec 2021?
To me this seemed like there wasn't enough information to solve this, give we are now considering a different year, "Abar" and "adue" will be different! Given "adue" is 8.166749 in December 2020, one might assume the policy matures in 2029, so at December 2021, "adue" will be 7.2 ish. and Abar will be around 0.86 (give 2% interest rate quoted in the question)
ACTED's miniASET and examiners report just show reusing the same "Abar" & "adue" values from part (ii)
SV = SA*Abar + expenses*130%*adue - premium*adue
SV = 100000*0.839868 + 130*8.166749 - 6292*8.166749
Is this genuinely correct, or was there an error in the question?
Seems to me, given the solution that Q4(ii) should asked for SV at the end of 2021.
