The two expressions on either side of the equal sign will have the same value if two numbers on the left-hand side are interchanged and two signs on the right-hand side are interchanged. What are those two numbers (not digits) and the two signs?

4 × 3 ÷ 6 + 2 – 8 = 10 + 2 × 3 ÷ 5 – 18​​

Given: 4 × 3 ÷ 6 + 2 – 8 = 10 + 2 × 3 ÷ 5 – 18

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

Option A) 2 and 4; + and × 

Option B) 4 and 6; ÷ and ×

6 × 3 ÷ 4 + 2 – 8 = 10 + 2 ÷ 3 × 5 – 18

​(Not integer)

​Option C) 4 and 8; + and ÷

8 × 3 ÷ 6 + 2 – 4 = 10 ÷  2 × 3 + 5 – 18

8 × $$\frac{1}{2}$$​ + 2 – 4 = 5 × 3 + 5 – 18

4 + 2 – 4 = 15 + 5 – 18

6 – 4 = 20 – 18

2 = 2 (Correct)

Thus, correct option is (c).

​Note: The given condition states that two numbers on the LHS and two signs on the RHS need to be interchanged.​
