You:: 12 years
Sister = (1/3)12 = 4 years
-------------------------
Next year::
You:: 12+1 = 13 yrs
Sister:: 4+1 = 5
--------
Ans: 13 is not three times 5

------
1 time older = 2x as old.
2 times older = 3x as old.
3 times older = 4x as old.
----------
Sister's age = S
You are 4*S = 12
S = 3

No.
You're 3 & 12.
Next year you'll be 4 & 13.
