Which of the following equations will be correct if numbers 2 and 8 and symbols – and ÷ are interchanged?

Option 2 : 2 – 4 ÷ 8 × 0.5 = 1

Let’s check each option,

1) 3 × 2 - 8 ÷ 5 = -3

Equation will become 3 × 8 ÷ 2 - 5 

Now, according to BODMAS rule we have:

3 × 8 ÷ 2 - 5 

= 3 × 4 - 5

= 12 - 5

= 7 ≠ -3

2) 2 – 4 ÷ 8 × 0.5 = 1

Equation will become 8 ÷ 4 – 2 × 0.5

Now, according to BODMAS rule we have:

8 ÷ 4 – 2 × 0.5

= 2 - 2 × 0.5

= 2 - 1

= 1

3) 16 - 2 ÷ 0 × 8 = 0

Equation will become 16 ÷ 8 – 0 × 2

Now, according to BODMAS rule we have:

16 ÷ 8 – 0 × 2

= 2 - 0 × 2

= 2 – 0

= 2 ≠ 0

4) 2 ÷ 8 + 9 – 0.18 = 10

Equation will become 8 – 2 + 9 ÷ 0.18

Now, according to BODMAS rule we have:

8 – 2 + 9 ÷ 0.18

8 – 2 + 50

56 ≠ 10

Hence, the correct equation is “2 – 4 ÷ 8 × 0.5 = 1”.
