What will come in the place of the question mark ‘(?)’ in the following equation, if ‘−’ and‘÷’ are interchanged and ‘×’ and ‘+’ are interchanged?

40 + 24 − 6 × 12 ÷ 3 = ?​​

Given: 40 + 24 − 6 × 12 ÷ 3 = ?

Given equation is solve by 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: 40 × 24 ÷ 6 + 12 - 3 = ?

40 × 4 + 12 - 3 = ?

160 + 12 - 3 = ?

172 - 3 = ?

? = 169

Thus, correct option is (a).
