Liam had 75% more magnets than John at first. Liam gave away 200% as many magnets as John. John was left with 25% of the magnets he had at first. What fraction of Liam's magnets did he have in the end?

Let John start  with   x  magnets  and Liam start  with (7/4) x  magnets

 

Note  that 200% as  many  must  be  twice as many  (100% as many  would  be  the  same number given away)

 

Then  John ended up with  v/4  magnets  and  gave away  (3/4)x

 

Liam   gave  away  2 ( 3/4)x = 6/4x  magnets  and  was  left  with  x/4  magnets

 

Notice  that  they  end up with  the  same number....so  John  has 100%  of Liam's  magnets
