What will come in the place of the question mark (?) in the following equation if '+' and '-' are interchanged and also '$$\times$$​' and '$$\div$$​' are interchanged?
12 - 104 $$\times$$​ 8 + 5 $$\div$$​ 4 = ?

Given:​ 12 - 104 $$\times$$ 8 + 5 $$\div$$ 4 = ?

'+' and '-' are interchanged, and also '$$\times$$​' and '$$\div$$​' are interchanged.

Logic: Interchange the given symbols in the given equation and then solve the equation using the BODMAS rule.

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

After interchanging the signs, we get, 12 + 104 $$\div$$ 8 - 5 $$\times$$ 4 = ?

12 + 13 - 5 $$\times$$ 4 = ?

12 + 13 - 20 = ?

25 - 20 = ?

(?) = 5​

Thus, 5 is the final answer.

So, the correct answer is (c).
