If M denotes 'addition', N denotes 'multiplication', O denotes 'subtraction', and Р denotes 'division', then what will be the value of the following equation?

55 N 2 М 27 О 16 P 4 = ?

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

55 N 2 М 27 О 16 P 4 = ?

? = 55 × 2 + 27 − 4

? = 110 + 27 - 4

? = 137 - 4

​Thus, correct option is (a) 133.​​​
