John's father is 5 times older than John

F = 5J

John is twice as old as his sister Alice.

J = 2A or A =.5J

In two years time, the sum of their ages will be

58. F+2 + J+2 + A+2 = 58F + J + A + 6 = 58

F + J + A = 58 - 6

F + J + A = 52:

How old is John now?:Substitute for F & A

5J + J +.5J = 52

6.5J = 52

J = 52/6.5

J = 8 yrs

John is 8 years old
