Which two signs should be interchanged to make the given equation correct?

24 ÷ 2 = 20 - 4 × 6 + 8​​

Given: 24 ÷ 2 = 20 - 4 × 6 + 8

Given equation is solve by BODMAS rule.

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

Now, we check each options.

Option (a): × and + (Not Follow)

New equation: 24 ÷ 2 = 20 - 4 + 6 × 8

12 = 20 - 4 + 6 × 8

12 = 20 - 4 + 48

12 $$\neq$$​ 64

Option (b): = and + (Follow)​

New equation: 24 ÷ 2 + 20 - 4 × 6 = 8

12 + 20 - 4 × 6 = 8

12 + 20 - 24 = 8

32 - 24 = 8

Option (c): - and + (Not Follow) ​

New equation: 24 ÷ 2 = 20 + 4 × 6 - 8

12 = 20 + 4 × 6 - 8

12 = 20 + 24 - 8

12 $$\neq$$ 36​

Option (d): ÷ and × (Not Follow)​

New equation: 24 × 2 = 20 - 4 ÷ 6 + 8

48 = 16 ÷ 6 + 8

48 = 24 ÷ 6

48 $$\neq$$​ 4

Thus, correct option is (b).
