$\begin{array}{l}\text{From the above question,}\\ \text{we can simplify as}\\ \\ \Rightarrow \frac{73}{100}\times 8523+\frac{32}{100}\times 6245=?\\ \\ \Rightarrow \text{73}\times \text{8523 + 32}\times \text{62.45 =?}\\ \\ \Rightarrow \text{\hspace{0.17em}? = 6221.79 + 1998.4}=\text{? }\\ \\ \Rightarrow ?\text{\hspace{0.17em}= 8220.19}\end{array}$

Hence, Option D is correct.
