Answer 2

The values of A, B, C is 8, 7, 6.

The clue to find the values of B is, since B is being multiplied with 9 in the units place which represents the expected output as 3, i.e., $B \times 9=3$ (Units place), which could be possible only for digit 7. So the value for B must be 7.

To find the value of A and C, let’s try the possible combinations.  The combinations are given in below attached image.

The value of A = 8 then there could be a chance of value $\bold{877 \times 999 = 876123}$. By comparing with the given question the value of A, B, C is 8, 7, 6.
