LoL! I actually got it a few moments ago but I was flooded with answers before I got the chance to delete it xD
anyways Queen is right.. Lita is 12 and her sister is 6.. Here's the solution I used... for the benefit of those having trouble solving age problems... ^.~
Present age
Lita: x+6
sis: x
4 years before:
Lita: (x+6)-4
sis: x-4
solution:
(x+6)-4 = 4(x-4)
x+2 = 4x-16
-3x = -18
x = 6
Present age:
Lita is 12
sis is 6
4 years ago:
Lita was 8
sis was 2
okay that's all...
wth I still can't choose the best answer!! my gosh! I still have to wait 4 hours...

dadoopie, Lita is 12 and her sister is 6.
L = S + 6
go back and find the age four year ago?
L = 4S
Thats: S + 6 = 4(S)
That means S = 2. keep in mind that was four years ago.
Add 4 to the (S)ister's 2 and you get 6. Add six to that for Lita's age and you get 12.

the difference between their ages will always remain the same right??
so, 4 years ago she was also 6 years older than her sister. so this is the model
4 YEARS AGO
L (lila) |_|_|_|_|
S (sis) |_|
since the difference is 6 yrs, then the 3 units must be 6 yrs.
3u= 6yrs
1u=6yrs divided by 3 = 2yrs
4u= 2yrs X 4 = 8yrs
8yrs= 4 years ago
now= 8yrs+4yrs
= 12 yrs
i'm 12 too... -.-

L-4=4(S-4)
L=?
Solution:

You have to make a simple algebraic equation to do this, there should only be one answer.
Unfortunately I can't as was never any good at it!
