$$\begin{gathered} \begin{array}{l}\text{Here,}\\ \text{?\% of 762 + 44\% of 568 = 52424}\\ \\ \text{ it can also be written as}\\ \\ \text{Now},\\ \Rightarrow x\%\text{\hspace{0.17em}of }762+44\times 5.68=\text{52424 }\\ \end{array} \\ [ put ? =x] \\ \begin{array}{l}\Rightarrow \frac{x}{100}\times 762+44\times 5.68=\text{52424}\\ \\ \Rightarrow \text{7.62}x\text{ = 52424}-\text{249.92}\\ \\ \Rightarrow \text{7 .62}x\text{ = 274.32}\\ \\ \Rightarrow x=\frac{274.32}{7.62}=36\\ \\ \Rightarrow x=36\end{array} \end{gathered}$$

Hence, Option B is correct.
