Mathematics

$PE=3.9cm, EQ=3cm, PF=3.6cm$ and $FR=2.4cm$. If $EF \parallel QR$ enter 1 else enter 0

SOLUTION
In the figure,
$\cfrac {PE}{EQ}=\cfrac{3.9}{3}=1.3$
$\cfrac {PF}{FR}=\cfrac{3.6}{2.4}=\cfrac{3}{2}=1.5$
$\Rightarrow$ $\cfrac {PE}{EQ}\ne \cfrac{PF}{FR}$
$\Rightarrow$ is not $\parallel$' $QR$ You're just one step away
