Arrange the numerals "123456789" to form a 9-digit number (referred to as "ABCDEFGHI") whose 2-digit subsets meet the following criteria:

1) AB is divisible by 2
2) BC is divisible by 3
3) CD is divisible by 4
4) DE is divisible by 5
5) EF is divisible by 6
6) FG is divisible by 7
7) GH is divisible by 8

There are two solutions.

 

[bla!!]

oops, didn't see above

121254245

12/2=4, 21/3=7, 12/4=3, 25/5=5, 54/6=9, 42/7=6, 24/8=3, 45/9=5


A-1
B-2
C-1
D-2
E-5
F-4
G-2
H-4
I-5

 

[Roshi229]

wow, on a roll

there's another solution

is it possible to only use each # once

 

[bla!!]

ohh, so you mutiply the 2 numbers together?

I thought you just took the number formed by each set of letters.
example: EF = 54, AB = 12

 

[Roshi229]

lol come to think of it, i'm not too sure... i got that last one online
i would assume that you are correct a*b=x where x/2= a whole number

 

[bla!!]

Yeah, otherwise that answer was waaay too easy.

My brain is gettin fried at the moment, I'll give that one a try later.
