10620 ÷ [(3/4) (72 + 66) - 20(3/4)] = ?
Formula Used:
Division of fractions: a ÷ (b/c) = a × (c/b)
Order of operations (BODMAS): Brackets → Orders (powers, roots) → Division → Multiplication → Addition → Subtraction

10620 ÷ [(3/4) (72 + 66) - 20(3/4)] = ?
⇒ 10620 ÷ [(3/4) (138) - 60/4)] = ?
⇒ 10620 ÷ [414/4 - 60/4] = ?
⇒ 10620 ÷ 354/4 = ?
⇒ 10620 × 4/354 = ?
⇒ 120
∴ Option 3 is the correct answer.
