What will come in the place of ‘?’ in the following equation, if ‘+’ and ‘–’ are interchanged and also ‘×’ and ‘÷’ are interchanged?
9 ÷ 145 × 29 – 75 + 13 = ?

Given: 9 ÷ 145 × 29 – 75 + 13 = ?

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

After interchanging,
9 × 145 ÷ 29 + 75 – 13
? = 9 × 5 + 75 – 13
? = 45 + 75 – 13

? = 120 – 13

Thus, correct option  is (d).
