MCQ
If $\frac{\text{x}}{2}-\frac{\text{x}}{3}=5,$ then $x =$
A
$8$
B
$16$
C
$24$
✓
$30$
✓
Answer
Correct option: D.
$30$
As, $\frac{\text{x}}{2}-\frac{\text{x}}{3}=5$
$\Rightarrow\frac{3\text{x}}{6}-\frac{2\text{x}}{6}=5$
$\Rightarrow\frac{\text{3x}-2\text{x}}{6}=5$
$\Rightarrow\frac{\text{x}}{6}=5$
$\Rightarrow\text{x}=5\times6 ($By transposing $6$ to $R.H.S.)$
$\therefore\text{x}=30$
Hence, the correct alternative is option $(d).$
