Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. -24

[ 3 × 6 - 3 {2 (2 ÷ 12\frac{1}{2} - 2) + 2 ÷ 12\frac{1}{2} } - 18]

= [ 3 × 6 - 3 {2 (4 - 2) + 2 ÷ 12\frac{1}{2} } - 18]

= [ 3 × 6 - 3 {4 + 2 ÷ 12\frac{1}{2} } - 18]

= [ 3 × 6 - 3 {4 + 4} - 18]

= [ 3 × 6 - 24 - 18]

= [18 - 24 - 18]

= -24

Therefore, the value of the expression is -24.
