mikes age is 3 times johns age. in twelve years, mike will be twice as old as john. how old are mike and John now?

Question

help me with the answer

 

Answer 1

Say John is x years old now, and thus Mike is 3x years old. In 12 years, Mike would be (3x+12) and John would be (x+12) years old. Therefore, according to the condition given by the problem,

 

(3x+12) = 2 * (x+12)

 

Solving for x from this equation, we will get John's current age. Three times x would be Mike's current age.
