Follow BODMAS rule to solve this question, as per the order is given below: Step-1: Parts of an equation enclosed in 'Brackets' must be solved first and in the bracket, Step-2: Any mathematical 'Of' or 'Exponent' must be solved next, Step-3: Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated, Step-4: Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated. (3 × 4 of 12 ÷ 2) ÷ 9 × 4 + 4 ÷ 8 + 3 × 2 ⇒ (3 × 48 ÷ 2) ÷ 9 × 4 + 4 ÷ 8 + 3 × 2 ⇒ (3 × 24) ÷ 9 × 4 + 4 ÷ 8 + 3 × 2 ⇒ 72 ÷ 9 × 4 + 4 ÷ 8 + 3 × 2 ⇒ 8 × 4 + 1/2 + 3 × 2 ⇒ 32 + 1/2 + 6 ⇒ 77/2
