Answer:
33 ⅓%
Step-by-step explanation:
Percent means out of 100, so write a proportion:

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
<span>J = 8 yrs
John is 8 years old</span>
