What will come in the place of the question mark (?) in the following equation, if ‘+’ and '-' are interchanged and ‘×’ and ‘÷’ are interchanged?
24 ÷ 10 + 68×2 – 16 = ?

Given: ​24 ÷ 10 + 68×2 – 16

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

After interchanging:

=24 × 10 - 68÷2 + 16
= 24 × 10 - 34 + 16 

= 240 - 34 + 16 

= 256 - 34 

Thus, correct option is (b).
