Solved each of the following Cryptarithms:
Solving for unit’s place,
7 + B = A
Solving for ten’s place,
3 + A = 9
∴ A = 6 and B = -1 which is not possible.
Hence, there is one carry in ten’s place, which means 7 + B >9
∴ now solving for ten’s place with one carry,
3 +A +1 = 9
∴ A = 5
For unit’s place subtracting 10 as one carry is given to ten’s place ,
7 + B - 10= 5
∴ B = 8
Hence, A = 5 and B = 8
