MCQ
If $\text{x}=15$ and $\text{y}=\frac{1}{30},$ then $x$ and $y$ are:
- ✓Inversely proportional.
- BDirectly proportional.
- CNeither directly nor inversely proportional.
- DCannot be determined.
$\text{x}=15,\text{y}=\frac{1}{30}$
$\frac{1}{30}=\frac{1}{2\times15}$
$\text{y}=\frac{1}{2\text{x}}$
Hence, $\text{y}\propto\frac{1}{\text{x}},$
Where $\frac{1}{2}$ is the proportionality constant.
