Answer
Solution: D
Amount of loan = L
Initial expected yield rate = 10.00%
Annual payment = [math]L/a_{\overline{10}|10\%}[/math]
Accumulated value at time 10 = [math]L/a_{\overline{10}|10\%})(S_{\overline{4}|10\%}1.07^6 + s_{6|7\%})[/math]
[[math]]
\begin{aligned}
\textrm{Yield Rate} = \left(\frac{\textrm{Accum Value}}{L}\right)^{1/10}-1 \\
=\left(\frac{s_{\overline{4}|10\%}+ s_{\overline{6}|7\%}}{a_{\overline{10}|10\%}}\right)^{1/10} - 1
\\
=\left(\frac{4.6410(1.5007)+7.1533}{6.1446}\right)^{1/10}-1 \\
=8.67\% \\
\end{aligned}
