    Question

    If + means −, − means ×, × means ÷ and ÷ means +, then what will come in place of the question mark (?) in the following equation?
    75 × 5 + 11 − 2 ÷ 18 = ?

    A.

    B.

    17

    C.

    26

    D.

    11

    Correct option is D

    Given:
    + → −, − → ×, × → ÷, ÷ → +
    Operation preference wiseSymbolBrackets[],,()Orders, of(power),(root),ofDivision÷Multiplication×Addition+Subtraction\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} ​​
    Expression:
    75 × 5 + 11 − 2 ÷ 18
    After replacing symbols:
    75 ÷ 5 − 11 × 2 + 18
    One continuous BODMAS process:
    75 ÷ 5 − 11 × 2 + 18
    = 15 − 11 × 2 + 18
    = 15 − 22 + 18
    = −7 + 18
    = 11
    Thus, correct option is (D).
