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.
