Arya is 3 years older than Cindi, and Kim is double Cindi's age. Lenny is 5 years older than Kim. Lenny is 17 years old. How old is Arya?

 

Let   Cindi's age  = C

Kim's age =  2C

Lenny's age = 2C + 5   = 17

 

Solving the last equation we have

 

2C + 5  = 17       subtract 5 from both sides

2C  =  12             divide both sides by 2

C  =  6   = Cindi's age.....and Arya  is three years older  = 9

 

 

cool cool cool

If Lenny is 5 years older than Kim, and Lenny is 17, then Kim is 12, Cindi is 6, anf Arya is 9.
