If '+' means '-', '-' means '$$\times$$', '$$\times$$' means '$$\div$$' and '$$\div$$' means '+' then, what is 8+ (3 - 2) $$\times$$​ 4 $$\div$$ 1 = ?​​

Given: 8 + (3 - 2) $$\times$$​​ 4 $$\div$$​ 1 = ?

Using 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 - (3 $$\times$$​ 2) $$\div$$​​​ 4 + 1 = ?

8 - 6 $$\div$$​​​​ 4 + 1 = ?

8 - 1.5 + 1 = ?

9 - 1.5 = ?

? = 7.5

Thus, correct option is (c).
