Answer
Solution: E
[[math]]
\begin{aligned}
& 90.17=4 a_{6 j}+X v^6 \\
& 132.47=4 a_{6 j}+1.6 X v^6
\end{aligned}
[[/math]]
Multiply the first equation by 1.6 :
[[math]]
144.272=6.4 a_{6 j j}+1.6 X v^6
[[/math]]
Subtract the second equation:
[[math]]
11.802=2.4 a_{6 / j}
[[/math]]
Use annuity calculation on BA II Plus
[[math]]
j=6 \%=\frac{i^{(2)}}{2}, i^{(2)}=12 \%
[[/math]]
