If ‘P’ stands for ‘÷’, ‘Q’ stands for ‘×’, ‘R’ stands for ‘+’ and ‘S’ stands for ‘−’, what will come in place of the question mark ‘?’ in the following equation?
(121 S 46) R 19 Q 5 R 126 P 6 S 38=?

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

(121 S 46) R 19 Q 5 R 126 P 6 S 38 =?

? = 75 + 19 × 5 + 126 ÷ 6 − 38

? = 75 + 19 × 5 + 21 - 38

? = 75 + 95 + 21 - 38

? = 191 - 38

Thus, the correct option is: (c)
