Show that the Crptarithm does not have any solution.

If B is multiplied by 4 then only 0 satisfies the above condition.


Hence, for unit place to satisfy the above condition, we have, B = 0.


Similarly for ten’s place, only 0 satisfies.


But, AB cannot be 00 as 00 is not a two digit number.


So, A and B cannot be equal to 0


Hence, there is no solution satisfying the condition .
