Karlo is now four times as old as Kevin. In 12 years, Karlo will be twice as old as Kevin. How old are Karlo and Kevin?
**
let x=Kevin's present age
4x=Karlo's present age
12 yrs hence:
(x+12)=Kevin's age
(4x+12)=Karlo's age
4x+12=2(x+12)
4x+12=2x+24
2x=12
x=6
4x=24
Kevin's present age=6
Karlo's present age=24
