$\begin{array}{l}Given that,\\ \Rightarrow \text{?\% of 762 + 44\% of 568 = 524.24}\\ \\ \text{It can also be written as}\\ \\ \Rightarrow x\text{\hspace{0.17em}\% of 762 +}\frac{44}{100}\times 568=524.24\\ \\ \text{[putting }x\text{ at the place of ?]}\\ \\ \Rightarrow \frac{x}{100}\times 762+44\times 5.68=524.24\\ \\ \Rightarrow x\times \text{7.62 = 524.24}-\text{44}\times \text{5.68}\\ \\ \Rightarrow \text{7.62}x\text{ = 524.24}-\text{249.92}\\ \\ \Rightarrow x=\frac{274.32}{7.62}=36\end{array}$

Hence, Option B is correct.
