A tiger has three wolves as his subordinates. The tiger asked three wolves to give him two prey every day, and the wolves could feed themselves the rest of the time. Every day, the three wolves are so busy paying tribute that they have nothing to do to find their own prey. They are all thin. Tigers are anxious about this situation, but they can't lose this sense of belonging. They still have to find their own food. The tiger consulted the learned fox and put forward a performance plan:

1. Give two prey weighing more than 20 kg every day, and the wolf will get 5 kg/prey.

2. If you pay tribute to two prey weighing more than 50kg every day, the wolf will get10kg/prey.

3. If you pay more than 2 100 kg of prey every day, the wolf will get 25 kg/prey.

4. Tribute 2 prey weighing more than 150 kg every day. In addition to the reward of 65,438+000 Jin, half of the excess weight over 65,438+000 Jin belongs to the wolf.

Seeing this goal, the wolf's enthusiasm was greatly improved and he stopped worrying about his food. On the contrary, he improved his hunting skills, developed new hunting grounds and had enough time for exercise.
