    Zahir is 36 years old

    Samantha is 28 years old

    (Wilbert is 32 years old)

    9*4=36

    7*4=28

    36-28=8

    Samantha: 28, Wilbert: 32, Zahir: 36.

    Step-by-step explanation:

    The difference of 2 ratio units corresponds to a difference of 8 years, so each ratio unit stands for 4 years.

    The ratio of ages in years is ...

    ... 4*7 : 4*8 : 4*9 = 28 : 32 : 36
