If 'A' stands for '÷', 'B' stands for '-', 'C' stands for '×' and 'D' stands for '+', what will come in place of the question mark (?) in the following equation?
36 B8 A 56 C 49 D 53 = ?

Given: ​36 B8 A 56 C 49 D 53

​$$\begin{array}{|c|c|} \hline\textbf{Operation preference wise} & \textbf{Symbol} \\\hline\text{Brackets} &[],{}, () \\ \hline \text{Orders, of} & (power), √ (root) , of \\ \hline \text{Division}& ÷ \\ \hline \text{Multiplication} & × \\ \hline \text{Addition} & + \\ \hline \text{Subtraction} & - \\\hline\end{array}$$ 

Now equation: 36 - 8 ÷ 56 × 49 + 53
? = $$36 - \frac{8}{ 56} × 49 + 53$$​​

? = 36 - $$\frac{1}{7}\times49$$​ + 53
? = 36 - 7 + 53 

? = 89 - 7 

Thus, correct option is (b).
