What will come in the place of the question mark ‘(?)’ in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged?
43 ÷ 9 − 988 × 2 + 11 = ?​

Given: 43 ÷ 9 − 988 × 2 + 11 = ?

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: 43 × 9 + 988 ÷ 2 - 11 = ?

43 × 9 + 494 - 11 = ?

387 + 494 - 11 = ?

881 - 11 = ?

? = 870

Thus, correct option is (c).
