Explanation:

To solve the expression, we need to replace the symbols with their actual mathematical operations as given:

- ‘+’ means ‘÷’

- ‘-’ means ‘+’

- ‘×’ means ‘-’

- ‘÷’ means ‘×’

Let's rewrite the expression with these operations:

1. Original Expression: 18 ÷ 6 - 27 + 3 × 12

2. Replacing symbols: 18 × 6 + 27 ÷ 3 - 12

Now, solve the expression following the order of operations (BODMAS/BIDMAS rule):

- Perform multiplication and division first:

- 18 × 6 = 108

- 27 ÷ 3 = 9

- Then perform addition and subtraction:

- 108 + 9 = 117

- 117 - 12 = 105

- Options:

- Option 1: 105

- Option 2: 92

- Option 3: 107

- Option 4: 95

- Correct Answer: Option 1: 105
