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?
128 A 4 C 16 B 7 D 5 = ?

Given:-

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

Then equation will become
128 ÷ 4 + 16 × 7 - 5
​​= 32 + 16 × 7 – 5

= 32 + 112 – 5
= 144 – 5
= 139 ​​
