Question

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

Answer 1

Zahir is 36 years old
Samantha is 28 years old
(Wilbert is 32 years old)

9×4=36
7×4=28
36-28=8

Answer 2

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

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
