We need to simplify the expression: 20 ÷ 5 of 4 × 8 + 6 ÷ 24 of 3 × 48 - 6 ÷ 18 × 9.
Concept:
We follow the BODMAS/BIDMAS rule which stands for Brackets, Orders (i.e. powers and square roots, etc.), Division and Multiplication, and Addition and Subtraction.
Calculation:
We have,
⇒ 20 ÷ 5 of 4 × 8 + 6 ÷ 24 of 3 × 48 - 6 ÷ 18 × 9
⇒ 20 ÷ 20 × 8 + 6 ÷ 72 × 48 - 6 ÷ 18 × 9
⇒ 1 × 8 + (1/12) × 48 - (1/3) × 9
⇒ 8 + 4 - 3
⇒ 12 - 3
⇒ 9
∴ The correct answer is 9.
