    Xian = 64+20m

    Kai = 76+16m

    set them equal

    (m = months)

    64 + 20m = 76+16m

    subtract 16 m from each side

    64+4m = 76

    subtract 64 from each side

    4m = 12

    m=3

    in 3 months they will have the same number of stamps

    64+20m = 64 + 20 (3) = 64+60 = 124

    in 3 months they will have the same number of stamps, 124
