Answer:
14
Step-by-step explanation:
We are given with two 
numbers whose first 
are same.
It is given that their sum is 
adding the last two corresponding digits gives,
Now adding the rest,
to get 
should not give anything to carry as that will make A in decimal to satisfy the addition.
Therefore,
Thus 
And finally,
Thus 
Now simplifying
Thus 
is the answer.
