Answer :

A + b = 0, 9, 18(9,0)(8,1)(7,2)(6,3)(5,4)(4,5)(3,6)(2,7)(1,8)(0,9)(0,0)(9,9)-------------------------------------------To be divisible by 9, the sum 6 + 3 + 1 + 8 + 7 + 2 + A + B = 27+ A + B must be divisible by 9→ A + B must be a multiple of 9.→ (A, B) must be (0, 0), (0, 9), (1, 8), (2, 7), (3, 6), (4, 5),(5, 4), (6, 3), (7, 2), (8, 1), (9, 0)Note that (0, 0) must not be forgotten as 27 + 0 + 0 = 27 = 3 ×9.
