MCQ
If $x = 15$ and $y = 1/30$, then $x$ and $y$ are:
- ✓Directly proportional
- BInversely proportional
- CNeither directly nor inversely proportional
- DCannot be determined
✓
Answer
Correct option: A.
Directly proportional
$x=15, y=1 / 30$
$1 / 30=1 /(2 \times 15)$
$y=1 / 2 x$
Hence, $y \propto 1 / x,$ where $1 / 2$ is the proportionality constant.
$1 / 30=1 /(2 \times 15)$
$y=1 / 2 x$
Hence, $y \propto 1 / x,$ where $1 / 2$ is the proportionality constant.
