    Step-by-step explanation:

    Let the common ratio of their ages be x

    Let the Hari’s age be 5x and Harry’s age be 7x

    Five years later:-

    Hari’s age=5x+4

    Harry’s age=7x+4

    According to question….

    5x+5 = 3

    7x+5    4

    By cross-multiplication,We get,

    4(5x+5)=3(7x+5)

    20x+20=21x+15

    20-15=21x-20x

    5=x

    x=5

    Present age of Hari=5x=5×5=25 years

    Present age of Harry=7x=7×5=35 years
