Question

Fill in the missing terms in the following tables, if $x$ and $y$ vary directly-

$x$	$10$	__	$30$	$46$
$y$	$5$	$10$	__	__

Answer 1

From $2^{nd}$ column,

$x=2y\Rightarrow y=\frac{x}{2}$

Therefore,

For $y=10\Rightarrow x=2\times 10=20$

For $x=30\Rightarrow y=\frac{30}{2}=15$

For $x=46\Rightarrow y=\frac{46}{2}=23$
