What will come in the place of the question mark (?) in the following equation, if '+' and '×' are interchanged and '-' and '÷' are interchanged?
28 - 4 × 12 ÷ 5 + 3 = ?

Given: 28 - 4 × 12 ÷ 5 + 3 = ?

Logic: BODMAS

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

After interchanging the sign, Equation becomes: 28 ÷ 4 + 12 - 5 × 3 = ?

28 ÷ 4 + 12 - 5 × 3 = ?

7 + 12 - 5 × 3 = ?

7 + 12 - 15 = ?

19 - 15 = ?

Thus, the correct option is (a) 4.
