John is twice as old as his friend peter.peter is 5 years older than Alice.in 5 years John will be three times as old as Alice .how old is peter now?

Reiny
Alice  x
Peter  x+5
John  2x+10
5 years from now:
John  2x+15
Alice  x+5
2x+15 = 3(x+5)
x = 0
x = 0
This question is bogus, even though the answer meets the original conditions.
Unless Alice was just born, it makes little sense
i.e.
Alice  0 years
Peter 5 years
John  10 years
in 5 years:
Alice = 5
Peter = 10
John = 15 > John is indeed 3 times as old as Alice
Check your typing of it, or the question itself
