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

32 × 5 + 12 ÷ 4 - 18 = 29​

​​

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

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

Check option A,​​÷ and ×​

32 × 5 + 12 ÷ 4 - 18 = 29

After interchanging,

32 ÷ 5 + 12 × 4 - 18 = 29

Here, 32 is perectly not divisible by 5.

So, its not correct option.

Check option B, ​​- and ×​​

32 × 5 + 12 ÷ 4 - 18 = 29

After interchanging,

32 - 5 + 12 ÷ 4 × 18 = 29

27 + 3 × 18 = 29

27 + 54 = 29

81≠29

So, its not correct option.

Check option C,​​- and +​

32 × 5 + 12 ÷ 4 - 18 = 29

After interchanging,

32 × 5 - 12 ÷ 4 + 18 = 29

160 - 3 + 18 = 29

175≠29

So, its not correct option.

Check option D, ​+  and ×​​

32 × 5 + 12 ÷ 4 - 18 = 29

After interchanging,

32 + 5 × 12 ÷ 4 - 18 = 29

32 + 5 × 3 - 18 = 29

32 + 15 - 18 = 29
