Corey is 104 years old. Zoe is 24 years old. How many years until Corey's age is 3 times Zoe's age?

Question

age problem

Answer 1

After adding x years to both Corey and Zoe's ages, Corey will be three times Zoe's age.

(104 + x) = 3 * (24 + x)

 

104 + x = 72 + 3x

 

32 = 2x

 

x = 16

 

Sixteen years from now, Corey will be 120 and Zoe will be 40.
