Find the value of $$[66 \div \{ 12 + 5 \times (6-4)\}]$$​​

Correct option is A

Given

​$$[66 \div \{ 12 + 5 \times (6-4)\}]$$​​

Formula 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:

​$$[66 \div \{ 12 + 5 \times (6-4)\}]$$​​

= $$[66 \div \{ 12 + 5 \times (2)\}]$$​​

= $$[66 \div \{ 12 + 10\}]$$​​

= $$[66 \div { 22}]$$​​

= $$\frac{66}{22} = 3$$​​
