Let,
the numbers be "x" and "y"
According to the question,
x = 4y ......................................................equation (1)

...................................equation (2)
Taking equation (2)

Substituting the value of "x" from equation (1), we get,





Cross multiplying, we get,


<u />



Now,
Taking equation (1)
x = 4y
Substituting the value of "y", we get

So, the numbers are
and
