Short Note

In which of the following table x and y vary inversely:

 x 4 3 12 1 y 6 8 2 24

#### Solution

$\text{ Since x and y vary inversely, we have: }$
$y = \frac{k}{x}$
$\Rightarrow xy = k$
$\therefore \text{ The product of x and y is constant } .$
$\text{ In all cases, the product xy is constant } (i . e . , 24) .$
$\text{ Thus, in this case, x and y vary inversely .}$
