Question
Find the value of 45 - 3 x (4 of 6 + 12 ÷ 3 × 6 – 4
× 5) + 6.Solution
45 - 3 × (4 of 6 + 12 ÷ 3 × 6 - 4 × 5) + 6 ⇒ 45 - 3 × (24 + 12 ÷ 3 × 6 - 4 × 5) + 6 ⇒ 45 - 3 × (24 + 4 × 6 - 4 × 5) + 6 ⇒ 45 - 3 × (24 + 24 - 20) + 6 ⇒ 45 - 3 × 28 + 6 ⇒ 45 - 84 + 6 ⇒ 51 - 84 ⇒ - 33 ∴ Required answer is - 33.
