${\sf{\green{\underline{\large{To\:find}}}}}$

• Numbers

${\sf{\pink{\underline{\Large{Explanation}}}}}$

Let the nos be. x and y

then

Ratios will be

=>2x=3y

=>x=3y/2

According to the questio

• And their differences is 21

x-y =21____(2)

=>3y/2 -y =21

=>y/2 =21

=>y=42

Putting values for x

X-y =21

=>x-42=21

=>x=63
