Hello Once Again,

Kim is 1/3 the age of her older siste Sue. In 13 years, Sue will be one year younger then twice Kim's age. How old is Sue?

Thank you,

Im sure someone will give you the "real" way to do this.

But in an instance like this, where you dont know where to begin, just do trial and error. It should take about 2 min., but at least you can come to the correct answer.

What is the answer? I came up with 36. Let me if its the right answer, and I will tell you how to solve it.

 

[Rezdawg]

36 is correct.
