If ‘+’ means ‘–’, ‘–’ means ‘×’, ‘×’ means ‘÷’, ‘÷’ means ‘+’, what will come in place of the question mark (?) in the following equation?

44 ÷ 120 × 5 – 2 + 10 × 2 = ?

Correct option is C

Given: ‘+’ means ‘–’, ‘–’ means ‘×’, ‘×’ means ‘÷’, ‘÷’ means ‘+’
Logic: interchange mathematical operators and solve as per BODMAS rule.

$$\begin{array}{|c|c|} \hline \textbf{Operation preference wise} & \textbf{Symbol} \\\hline Brackets &[],{}, () \\ \hline Orders, of & (power), √ (root) , of \\ \hline Division& ÷ \\ \hline Multiplication & × \\ \hline Addition & + \\ \hline Subtraction & - \\\hline \end{array}$$​
Given:
44 ÷ 120 × 5 – 2 + 10 × 2
After interchanging,
44 + 120 ÷ 5 × 2 - 10 ÷ 2
= 44 + 24 × 2 - 5
= 44 + 48 – 5
= 87
Thus, correct option (c).
