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?
9 B 4 D 18 A 9 C 12 = ?

Given: 9 B 4 D 18 A 9 C 12 = ?

Using BODMAS rule.

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

New equation: 9 × 4 - 18 ÷ 9 + 12 = ?

9 × 4 - 2 + 12 = ?

36 - 2 + 12 = ?

48 - 2 = ?

? = 46

Thus, correct option is (d).
