Answer

In 1st column $A + A = 0A = 0$ or $5$
For $A = 0$, the second & third column, sums are not satisfied
So, $A = 5$
Now, in second column
$B + B + 1 = 3$
For $B = 1$, third column sum is not satisfied.
So, $B = 6$
Again, in third column, $C + C + 1 = 1A$
$C + C = 15 − 1$
$2C = 14$
$C = 7$
Hence, $A = 5, B = 6$ and $C = 7$
