A cannot be 3 or larger because the sum would then be a three digit number.  Hence, A is either 2 or 0.  Let A represent 2, then 4 times B is either 2 or 12.  If 4 times B is 2, then B would have to be 1/2 which is not a digit 0-9, so if A is 2, 4 times B must be 12, which means B is 3.  Then 4 times 2 is 8 plus the carry is 9 and C is 9.
