Expert Answer:

Here, at unit's place A x 5 = _A

That is we need to search for a number, which when multiplied to 5 gives the same unit place.

Such a number is 5 or 0, as 5 x 5 = 25 or 0 x 5 = 0

Case (1) Taking 5 in place of A, we get

Here, B can take the value 2, which satisfy the condition, taking, B = 2, we get

Thus, A = 5, B = 2 and C = 1

Case (2) Taking 0 in place of A, we get

Here B can take the value 5, which satisfy the condition, taking B = 5, we get

Thus, A = 0, B = 5 and C =2.
