Which two signs need to be interchanged to make the following equation correct?
$9+3-15×5÷8=2$

–, ÷

+, –

×, +

×, ÷

Solution

Correct option is A

Given:

9+3-15×5÷8=2

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 ÷)

New equation: 9 + 3 ÷ 15 × 5 - 8 = 2

9 + 0.2

\times

5 - 8 = 2

9 + 1 - 8 = 2

10 - 8 = 2

2 = 2

Option (b): (+ and -)

New equation: 9 - 3 + 15 × 5 ÷ 8 = 2

9 - 3 + 15 × 5 ÷ 8

\neq

Option (c): (× and +)

New equation: 9 × 3 - 15 + 5 ÷ 8 = 2

9 × 3 - 15 + 5 ÷ 8

\neq

Option (d): (× and ÷)

New equation: 9 + 3 - 15 ÷ 5 × 8 = 2

9 + 3 - 3

\times

8 = 2

9 + 3 - 24 = 2

12 - 24 = 2

- 12

\neq

Thus, the correct option is (a).
