Question

$x$ and $y$ are inversely related. If $x=5$ and their constant of proportionality is 6, then find the value of $y$.

• A. $\frac{6}{5}$
• B. $\frac{5}{6}$
• C. $\frac{3}{2}$
• D. $\frac{1}{5}$

Answer 1

The correct option is A $\frac{6}{5}$

Given,
$x\propto \frac{1}{y}$

$Hence,x\times y=\text{proportionality constant}$
$\Rightarrow 5\times y=6$
$\Rightarrow y=\frac{6}{5}$
