    Question

    If 28 ×\times​ 8 ×\times​ 988 ÷2704\div \sqrt{2704} = y + 649, then find the value of y.​

    A.

    3617

    B.

    3609

    C.

    3607

    D.

    3608

    Correct option is C

    Given:

    28 × 8 × 988 ÷ 2704\sqrt{2704} = y + 649

    Concept Used:

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

    Solution: 

    28 × 8 × 988 ÷ 2704\sqrt{2704} = y + 649

    y = (28 × 8 × 988 ÷ 52) − 649

    y = (28 × 8 × 19) − 649

    y = 4256 − 649

    y = 3607

    Option (C) is right.
