12÷( 1- 1 4 ×2),

= 12÷ 1 2 ,

=24 (kg),

Now Xiaomei has the weight of beef jerky:

12+24×14 =18 (kg);

It turns out that Austrian zebras have the weight of beef jerky:

18÷( 1- 1 3 ),

= 18× 3 2 ,

=27 (kg);

It turns out that Ou Ou has the weight of beef jerky:

24-(27× 1 3 ),

=24-9,

= 15 (kg);

A: It turns out that Europe and Europe have 15 kg of beef jerky.
