If A is 55, Z is 11, H is 5 and D is 5, then find the value of A ÷ Z × H – D.

Given: A = 55, Z = 11, H = 5, D = 5, A ÷ Z × H – D.

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

= 25 - 5 

= 20

Thus, the correct option is (A) 20.
