this one is really simple, i think divide it as half (6-6)9 Z+ A" H3 Z5 ^# p# s- ^1 c
weigh 3-3 , if one side is heavier, weigh 1-1 -> you will know which one is heavier7 i' ]! t9 B7 a" e7 d& T/ t4 V
If the above doesnt work
+ D2 I$ h0 g5 O4 b& p5 u- Vweigh 3-3 of the other group (2nd chance)
& n- i0 c! N$ Y* `! g+ ythen weigh 1-1 from heavier group (3rd chance)-> you will know which is heavier |
