:) (Though the question never says they're still alive, raising all sorts of deep philosophical question regarding whether one can continue to age after death.)

Double-check your work on this one. (I'm assuming the question means "Three years ago, A's age was 4 times that of B, and four years from now, A's age will be 3 times that of B.)

A-3=4(B-3) and A+4=3(B+4), B=17 and A=59. Hence, the correct answer is B.
