Find the value of 7 + {4 + 3 of 4 – (5 + 3 – 6 ÷ 2)}.

Correct option is C

Given:

​7 + {4 + 3 of 4 – (5 + 3 – 6 ÷ 2)}.

Concept Used:

BODMAS Rule : 

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

Solution:

= 7 + {4 + 3 $$\times$$​ 4 – (5 + 3 – 6 ÷ 2)}.

= 7 + {4 + 3 $$\times$$​ 4 – (8 – 3)}

= 7 + {4 + 3 $$\times$$4 – 5}

= 7 + {4 + 12 – 5}

= 7 + 11

= 18
