Question:
Solve each of the following Cryptarithm:
Solution:
Two possibilities of A are :
(i) If $\mathrm{B}+7 \leq 9, \mathrm{~A}=6$
But clearly, if $\mathrm{A}=6, \mathrm{~B}+7 \geq 9$; it is impossible
(ii) If $\mathrm{B}+7 \geq 9, \mathrm{~A}=5$ and $\mathrm{B}+7=5$
Clearly, $\mathrm{B}=8$
$\therefore \mathrm{A}=5, \mathrm{~B}=8$
