    Let’s denote Anu’s current age as A and Sonu’s current age as S.

    Five years ago:

    Anu’s age: A – 5

    Sonu’s age: S – 5

    Given that Anu was thrice as old as Sonu five years ago:

    A−5=3⋅(S−5)

    after 10 years:

    Anu’s age: A + 10

    Sonu’s age: S + 10

    Given that Anu will be twice as old as Sonu after 10 years:

    A+10=2⋅(S+10)

    Solve these equations: and you get A=35 years, S=20 years
