What will come in place of the question mark (?) in the following equation, if ‘×’ is replaced by ‘÷’, ‘÷’ is replaced by ‘+’, ‘+’ is replaced by ‘×’ and ‘−’ remains unchanged?

42 × 3 ÷ 4 + 9 − 17 = ?​​

Given: 42 × 3 ÷ 4 + 9 − 17 = ?  

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

 New Equation: ​42 ÷ 3 + 4 × 9 − 17 = ?  

? = 14 + 4×9 − 17

? = 14+36 - 17   

? =  50 - 17

Thus, correct option is (b).
