Question

The constant of proportionality is 27. If $x\text{and}y$ are inversely related and $y$ = 9,
then find $x$.

• A. 5
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is C 3

Given, $x\text{and}y$ are inversely related
$\text{and}y=9$

$\because \text{Proportionality constant}=x\times y$
$\Rightarrow 27=x\times 9$
$\Rightarrow x=\frac{27}{9}=3$
