Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.
20 * 96 * 66 * 11 * 10 * 56

Logic: interchange mathematical operators and solve as per BODMAS rule.

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

20 * 96 * 66 * 11 * 10 * 56

After interchanging,

20 + 96 - 66 ÷ 11 × 10 = 56

116 - 6 × 10 = 56

116 - 60 = 56

20 * 96 * 66 * 11 * 10 * 56

After interchanging,

20 + 96 - 66 ÷ 11 = 10 × 56

116 - 6 = 560

110≠560

So, its not correct option.

20 * 96 * 66 * 11 * 10 * 56

After interchanging,

20 - 96 × 66 ÷ 11 + 10 = 56

30 - 96 × 6 = 56

30 - 576 = 56

546≠56

So, its not correct option.

Check option D, – , + , ÷ ,×, =

20 * 96 * 66 * 11 * 10 * 56

After interchanging,

20 - 96 + 66 ÷ 11 × 10 = 56

20 - 96 + 6 × 10 = 56

20 - 96 + 60 = 56

-16≠56

So, its not correct option.

Thus, correct option is (a).
