MCQ
If $\frac{\text{x}}{2}=3,$ then the value of $3x + 2$ is:
  • ✓
    $20$
  • B
    $11$
  • C
    $\frac{13}{2}$
  • D
    $8$
✓

Answer

Correct option: A.
$20$

Given, $\frac{\text{x}}{2}=3$
On muliplying both sides by 2, we get $\frac{\text{x}}{2}\times2=3\times2$
$\Rightarrow\text{x}=3\times2=6$
Put $x = 6$ in the equation $3x + 2,$ we get
$3(6) + 2 = 18 + 2 = 20$
