Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
there is no carry from the hundreds column to the thousands column , so A is less than 4

three times D is a number with A in the ones place
___ three times 1 is 3
___ three times 4 is 12
___ three times 7 is 21

if A equaled 3 ; then D would equal 1 and N would equal 9
____ but this would result in a carry from the tens column to the hundreds column , and a carry to the thousands column

if A equaled 2 ; then D would equal 4 and N would be at least 6
___ this works with N equal to 7 , and B equal to 6

if A equaled 1 ; then D would equal 7 and N would be at least 3
___ N must equal 5 for the sum of the tens column and the carry and sum of the hundreds column to fit
___ BUT , this leaves B equal to 1 (the same as A)

so the second scenario is the one you want
