Question

$x \: and \: y \: are \: two \: variable \: such \: that \: x \alpha y. \: obtain \: a \: relation \: between \: x \: and \: y \: if \: x = 20. \: y = 4.$
​

Answer 1

$It \:is \:given \:that , x \alpha y .x ,y \:are \\in \:direct \: variation .$

$\frac{x}{y} = constant$

$If \: x = 20, \:and \:y = 4 \: then \\constant (k) = \frac{20}{4}$

$\implies k = 5$

Therefore.,

$\red { \frac{x}{y} } \green { = 5 }$
