Full rent A: The number of vehicles is 27/8=3.375, so we have to rent 4 vehicles, and the transportation fee is 4*300= 1200 yuan;
Full rent B: Then the number of vehicles needed is 27/4=6.75, so we have to rent 7 vehicles, and the transportation fee is 7*200= 1400 yuan;
Both Party A and Party B rent: The analysis shows that Party A's freight is 300/8 and Party B's freight is 200/4, which means that Party A rents three cars and the other three can rent one car. Freight =3*300+200= 1 100 yuan.
2. There is a relationship between them: the number of people in workshop 1 minus one fifth is equal to the number of people in workshop 2 plus one fifth of workshop 1. This means that workshop 2 is three-fifths of workshop 1, so workshop 1 is 5: 3 compared with workshop 2.
3. 1200-740=460 (person)
If there are x chickens, there are 30-X rabbits.
Then it is: 2X-4(30-X)=80 and X=20.
