Let Rita and (I think it's wrong by autocorrect) Fita be 5x and 7x respectively.
After 4 years, their ages will be 3x=5x+4 and 4x=7x+4
ATQ,
5x+4/7x+4=3x/4x
5x+4/7x+4=3/4
Cross multiplication
20x+16=21x+12
20x-21x=-16+12
-x=-4
x=4
Therefore Rita's and Fitas ages are 4(5)=20 and 4(7)=28 respectively.
