What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
11 + 37 − 5 × 40 ÷ 24 = ?

Correct option is D

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; 11 - 37 + 5 ÷ 40 $$\times$$​ 24 = ?

? = 11 - 37 + $$\frac {5} {40}$$ $$\times$$ 24

? = 11 - 37 + $$\frac {24} {8}$$

? = 11 - 37 + 3

? = 14 - 37

? = - 23

Thus, correct option is (d).
