What is the value of 3.6 × 1.62 + 0.48 × 3.61.8 × 0.8 + 10.8 × 0.3 - 2.16?

Answer: Option D

$$\begin{array}{rl}& \frac{3.6\times 1.62+0.48\times 3.6}{1.8\times 0.8+10.8\times 0.3-2.16}\\ & =\frac{\frac{1}{1000}\left[36\times 162+48\times 36\right]}{\frac{1}{100}\left[18\times 8+108\times 3-216\right]}\\ & =\frac{1}{10}\left[\frac{36\left(162+48\right)}{18\left(8+18-12\right)}\right]\\ & =\frac{1}{10}\left[\frac{36\times 210}{18\times 14}\right]\\ & =3\end{array}$$
