Kim is 1/3 older than Marlon. Marlon is 1/3 older than Aaron. Their total age is 222. How old is Kim, Marlon and Aaron?

Question

Need help please. I forgot my algebra book.

Answer 1

K = 4/3*M 

M = 4/3*A

 

K + M + A = 222

 

Substituting in: K = 4/3*M = 16/9*A

 

So we have A(16/9 + 4/3 + 1) = 222

 

A(16+12+9)/9 = 222

 

 

A = 54

 

Therefore M = 4/3 A = 72

 

And finally K = 4/3 M = 96
