MCQ
What is the solution set for $0<−\frac{\text{x}}{2} < 3$
  • A
    $(−6, 6)$
  • $(−6, 0)$
  • C
    $(0, 6)$
  • D
    $(-\infty, -6)$

Answer

Correct option: B.
$(−6, 0)$
Given: $0<−\frac{\text{x}}{2} < 3$
Multiply by 2 in above inequality (Here 2 is a positive number so the direction of the inequality does not change)
$\Rightarrow0 <-\text{x}<6$
$\Rightarrow−6 <\text{x}<0$
$\therefore\text{x}$ lies in $(−6, 0)$
