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. (6 of 4 ÷ 16 × 48) ÷ 8 × 4 + 2 × 3 ÷ 6 + 5 (6 - 2) ⇒ (24 ÷ 16 × 48) ÷ 8 × 4 + 2 × 3 ÷ 6 + 20 ⇒ (3/2 × 48) ÷ 8 × 4 + 2 × 1/2 + 20 ⇒ 72 ÷ 8 × 4 + 2 × 1/2 + 20 ⇒ 9 × 4 + 1 + 20 ⇒ 36 + 21 ⇒ 57 ∴ The value of the expression is 57.
