Answer 1

BODMAS

According to the question, after interchanging of numbers and mathematical signs:

So, Given equations : 

I. 6 + 4 - 9 × 3 ÷ 1 ⇒ 6 + 4 - 9 ÷ 1 × 3

⇒ 6 + 4 - 9 × 3

⇒ 6 + 4 - 27

⇒ 10 - 27

⇒ -17

II. 4 × 3 - 1 + 8 ÷ 2 ⇒ 4 ÷ 1 - 3 + 8 × 2

⇒ 4 - 3 + 8 × 2

⇒ 4 + 16 - 3

⇒ 20 - 3

⇒ 17

Thus, according to the question values for equation I and II are (-17) and 17 respectively.

Hence, "Option - (2)" is the correct answer.
