Question

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

x	4	3	12	1
y	6	8	2	24

Answer 1

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