Given: 30 – 2 ÷ 6 + 18 × 6 = ?

BODMAS

Decoding the given information:

Symbol	+	-	×	÷
Means	-	×	÷	+

Now replacing the sign from left to right using BODMAS Rule, we get:

Original: 30 – 2 ÷ 6 + 18 × 6

Decoded: 30 × 2 + 6 - 18 ÷ 6

⇒ 30 × 2 + 6 - 18 ÷ 6

⇒ 30 × 2 + 6 - 3

⇒ 60 + 6 - 3 = 63

Hence, the correct answer is "Option 2".
