If ‘A’ denotes ‘+’, ‘B’ denotes ‘×’, ‘C’ denotes ‘−’ and ‘D’ denotes ‘÷’, then what will come in place of ‘?’ in the following equation?

(35 A 7 B 2) D 7 C (14 D 2 C 6) A 6 = ?

Given: ‘‘A’ denotes ‘+’, ‘B’ denotes ‘×’, ‘C’ denotes ‘−’ and ‘D’ denotes ‘÷’

Logic: interchange alphabetical letters by mathematical operators and solve as per BODMAS rule.

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

(35 A 7 B 2) D 7 C (14 D 2 C 6) A 6

After interchanging,

(35 + 7 × 2) ÷ 7 - (14 ÷ 2 - 6) + 6

=(35 + 14) ÷ 7 - (7 - 6) + 6

=49 ÷ 7 - 1 + 6

=7+5
