Step-by-step explanation:
Correct option is
A
9
As the right hand digit of the sum of A+B+C=C,
it means that A+B=10 so A or B, none can be 0.
Also, the sum of A+B+C can not exceed 19.
So, 1 is carried to the second column.
Now, 1+A+B+C gives A as the right digit of the sum.
So, A=C+1.
Further, again 1 is carried over to the third column as A
cannot be 0 and the sum of 1+A+B+C can be at most 19.
On adding A+B+C+1 we get BA, thus here B=1.
Using A+B=10,A=10−1=9
Also, A=C+1
⇒C=A−1=9−1=8.
So, A=9,B=1 and C=8 satisfy all the conditions.
So, option A is correct.
I hope it helps
