What will come in the place of question mark (?) in the following equation, if ‘+’ and ‘−‘ are interchanged and ‘×’ and ‘÷’ are interchanged?

99 ÷ 9 − 999 × 9 + 99 = ?​​

Given: 99 ÷ 9 − 999 × 9 + 99 = ?

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

New expression:  99 ÷ 9 − 999 × 9 + 99 = ?

99 × 9 + 999 ÷ 9 −  99 = ?

99 × 9 + 999 ÷ 9 − 99 = ?

891 + 111 − 99 = ?

1102 − 99 = ?

Thus, correct option is (c).
