Find the value of $$[(32\div8) × \{\frac{15}{5}+\frac{30}{5} × (7-2)\}]$$​​

Correct option is B

Given:

​$$\left[ \left( \frac{32}{8} \right) \times \left\{ \frac{15}{5} + \frac{30}{5} \times (7 - 2) \right\} \right]$$​​

Concept Used:

​$$\begin{array}{|c|c|} \hline \textbf{Operation preference wise} & \textbf{Symbol} \\ \hline Brackets &[],{}, () \\ \hline Orders, of & ² (power), √ (root) , of \\ \hline Division & ÷ \\ \hline Multiplication & × \\ \hline Addition & + \\ \hline Subtraction & - \\ \hline \end{array}$$ 

Solution:

=$$\left[ \left( \frac{32}{8} \right) \times \left\{ \frac{15}{5} + \frac{30}{5} \times (7 - 2) \right\} \right]$$ 

$$=\left[ \left( 4 \right) \times \left\{ 3 + \frac{30}{5} \times (5) \right\} \right]$$ 

​$$=\left[ \left( 4 \right) \times \left\{ 3 + {30} \right\} \right]$$ 

​$$=\left[ 4\times \ 33 \right]$$ 

= 132
