We need B x 3 = $box enclose blank end enclose$ B
Since 5 x 3 = 15

∴ Possible value of B can be 5
Also 0 x 3 = 0, i.e. B = 0 can be another possible value

∵     A x 3 = A + 0 = A
∴ Possible value of A = 5
30, B must be
                                   5 0
                                 x 3
                  ______
