Samantha, Wilbert and Zahir have ages in ratio of 7:8:9. Zahir is 8 years older than Samantha. What are their ages?

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
