Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e 19.

 [18 - 3 × {3 - 3 × (3 ÷ 13\frac{1}{3}- 3) + 3 ÷ 13\frac{1}{3}+ 3} - 4 × 2]

⇒ [18 - 3 × {3 - 3 × (3 × 3 - 3) + 3 × 3 + 3} - 8]

⇒ [18 - 3 × {3 - 3 × (9 - 3) + 9 + 3} - 8]

⇒ [18 - 3 × {3 - 3 × 6 + 9 + 3} - 8]

⇒ [18 - 3 × {3 - 18 + 9 + 3} - 8]

⇒ [18 - 3 × {15 - 18} - 8]

⇒ [18 - 3 × - 3 - 8]

⇒ [18 + 9 - 8}]

⇒ 27 - 8 = 19
