If A denotes '+', B denotes '$$\times$$​', C denotes '-', and D denotes '$$\div$$​', then what will be the value of the following equation?

15 A 10 B 24 D 12 C 5 = ?

Given: 15 A 10 B 24 D 12 C 5 = ?​​

Given equation is solve by BODMAS rule.

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

New equation: 15 + 10 $$\times$$​ 24 $$\div$$ 12 - 5 = ?

15 + 10 $$\times$$​ 2 - 5 = ?

15 + 20 - 5 = ?

35 - 5 = ?

? = 30

Thus, correct option is (d).
