If ‘A’ stands for ‘÷’, ‘B’ stands for ‘×’, ‘C’ stands for ‘+’ and ‘D’ stands for ‘−’, then what will come in place of the question mark (?) in the following equation?
9 B 5 D 12 A 2 C 11 = ?

Correct option is A

Given: 9 B 5 D 12 A 2 C 11 = ?

Logic: BODMAS
​$$\begin{array}{|c|c|} \hline\textbf{Operation preference wise} & \textbf{Symbol} \\\hline\text{Brackets} &[],{}, () \\ \hline \text{Orders, of} & (power), √ (root) , of \\ \hline \text{Division}& ÷ \\ \hline \text{Multiplication} & × \\ \hline \text{Addition} & + \\ \hline \text{Subtraction} & - \\\hline\end{array}$$​​
New equation:  9 × 5 - 12 ÷ 2 + 11 = ?
9 × 5 - 6 + 11 = ?
45 - 6 + 11 = ?
56 - 6 = ?
?  = 50
Thus, the correct option is (A) 50.
