Answer :
We have condition as:
B+1=8.So, we got B=7
Also we have A+B=1
\(\Rightarrow\) A+7=11
A must be 4 to get unit's digit of A+7 as 1.So, A=4
And the last condition we have 2+A+1(carry)=B
Checking the values of A and B if it satisfies or not:
We have A=4 and B=7.Substituting, we have:
LHS: 2+A+1=2+4+1=7
RHS: B=7
Hence the values are verified.So we have A=4 and B=7
