What will come in the place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
127 ÷ 5 + 707 × 7 − 38 = ?​

 Given; 127 ÷ 5 + 707 × 7 − 38 = ?

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

 New equation: 127 × 5 - 707 ÷ 7 + 38 = ?

127 × 5 - 101 + 38 = ?

635 - 101 + 38 = ?

673 - 101 = ?

Thus, correct option is (a).
