Solutions:

$\begin{align} HCV &= \frac{1}{100} [8080 C+34500(H- \frac{O}{8}) +2240 S] \\ &= \frac{1}{100} [8080 + 70+34500(10-23/8) +2240 \times 1.5] \\ &= \frac{1}{100} [565600 + 34500 (10-1) \times 3360] \\ &= \frac{1}{100} [642272.5] \\ &= 6422.725kcal/kg \\ \end{align}$

Answer:

$HCV/GCV=6422.725 \space kcal/kg$
