What will be the value of the following expression if the ‘÷’ and the ‘+’ signs are interchanged?

8 − 4 × 2 ÷ 7 − 1 ÷ 5 − 8 + 4 × 1

Given: 8 − 4 × 2 ÷ 7 − 1 ÷ 5 − 8 + 4 × 1

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: 8 − 4 × 2 + 7 − 1 + 5 − 8 ÷ 4 × 1 = ?

8 − 4 × 2 + 7 − 1 + 5 − 2 × 1 = ?

8 − 8 + 7 − 1 + 5 − 2 = ?

20 − 11 = ?

? = 9

Thus, correct option is (c).
