    Question

    Which of the following options is the closest approximate value which will come in place of question mark(?) in the following equation?
    (√360+12÷6×3-√170)÷2=?

    A.

    4

    B.

    6

    C.

    5

    D.

    8

    Correct option is B

    Given:

    (√360+12÷6×3-√170)÷2=?

    Concept used:

    Bodmas rule:

    Operation preference wiseSymbolBrackets[],,()Orders,of(power),(root),ofDivision÷Multiplication×Addition+Subtraction\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}

    Solution:

    (√360+12÷6×3-√170)÷2=?

    (360 +126×3170)÷2\left(\sqrt{360\ }+\frac{12}{6}\times3-\sqrt{170}\right)\div2

    = (18.97 + 6 -13.04) ÷2\div2

    = (24.97 - 13.04) ÷2\div2

    = 11.93 ÷2\div2

    = 5.97

    The closest approximate value is 6.​
