What will come in the place of the question mark ‘(?)’ in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
175 ÷ 5 + 213 × 3 − 75 = ?​

Given: 175 ÷ 5 + 213 × 3 − 75 = ?

Given equation is solve by BODMAS rule.

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

New equation: ​​175 × 5 - 213 ÷ 3 + 75 = ?

175 × 5 - 71 + 75 = ?

875 - 71 + 75 = ?

950 - 71 = ?

? = 879

Thus, correct option is (b).
