If ‘A’ stands for ‘×’, ‘B’ stands for ‘−’, ‘C’ stands for ‘+’, and ‘D’ stands for ‘÷’, then the resultant of which of the following will be 9?

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

 Check options;

Option a) 8 B 3 A 10 C 2 D 5

= 8 - 3 × 10 + 2 ÷ 5

Option a) 8 B 3 C 10 A 2 D 5

= 8 − 3 + 10 × 2 ÷ 5

= 8 − 3 + 4

= 12 − 3 

= 9 (Correct)

Thus, correct option is (b).
