john is twice jane's age. In 2 years time, john will be twice as old as Jill and she will be twice as old as Jane's age 2 years ago. How old are John, Jill and jane??
***
let x=jane's present age
2x=john's present age
in 2 yrs time:
x+2=jane's age
2x+2=john's age
(2x+2)/2=jill's age(half john's age)
2x=also jill's age(twice as old as jane 2 yrs ago)
2x=x+1
x=1
jane's present age=1
john's present age=2
jill's present age=2
