What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘×’ are interchanged and ‘−’ and ‘÷’ are interchanged?
38 ÷ 7 + 5 × 20 − 4 = ?

Correct option is C

Given: 38 ÷ 7 + 5 × 20 − 4 = ?

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:  38 - 7 × 5 + 20 ​÷ 4 = ?
38 - 7 × 5 + 5 = ?
38 - 35 + 5 = ?
43 - 35 = ?
? = 8
Thus, the correct option is (C) 8
