Solve each of the following Cryptarithms: (iii) `A1+1B B0`

Explanation

Firstly let us solve for unit’s place,
`1+B=0`
Which means that `B=-1` which is not possible.
So, there should be one carry in ten’s place,
`A + 1 +1 = B` ---- (1)
For unit’s place, we need to subtract `10` as one carry is given in ten’s place,
`1+B-10=0`
`B=101=9`
Substituting `B=9` in (1),
`A+1+1=9`
`A =9-1-1=7`
Therefore, `A=7` and `B=9`
