Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 27.
[40 - 48 ÷ 4 of 3] ÷ {(6 + 4) - 4 of 4 + 4 + (6 - 4) + (4 × 4) ÷ 4} × 3
⇒ [40 - 48 ÷ 4 × 3] ÷ {(6 + 4) - 4 of 4 + 4 + (6 - 4) + (4 × 4) ÷ 4} × 3
⇒ [40 - 48 ÷ 12] ÷ {10 - 16 + 4 + 2 + 16 ÷ 4} × 3
⇒ [40 - 48 ÷ 12] ÷ {10 - 16 + 4 + 2 + 4} × 3
⇒ [40 - 48 ÷ 12] ÷ {20 - 16} × 3
⇒ [40 - 4] ÷ 4 × 3
⇒ 36 ÷ 4 × 3
⇒ 9 × 3 = 27
