Correct Answer: C
Solution :
\[\frac{\begin{align} & {{(1.5)}^{3}}+{{(4.7)}^{3}}+{{(3.8)}^{3}} \\ & -3\times 1.5\times 4.7\times 3.8 \\ \end{align}}{\begin{align} & {{(1.5)}^{2}}{{(4.7)}^{2}}+{{(3.8)}^{2}}-1.5\times 4.7- \\ & 4.7\times 3.8-3.8\times 1.5 \\ \end{align}}\] \[\frac{\begin{align} & (1.5+4.7+3.8)\,[{{(1.5)}^{2}}+{{(3.8)}^{2}}+{{(4.7)}^{2}}-1.5 \\ & \times 4.7-4.7\times 3.8-3.8\times 1.5] \\ \end{align}}{\begin{align} & {{(1.5)}^{2}}+{{(4.7)}^{2}}+{{(3.8)}^{2}}-1.5\times 4.7-4.7 \\ & \times 3.8-3.8\times 1.5 \\ \end{align}}\] \[=1.5+4.7+3.8=\]
