Several simple practical questions 1. Make a batch of small farm tools. The first workshop can process 50 pieces a day. If the second workshop does it for 10 days, it can complete the task. Now the two workshops cooperate. When this batch of tasks are completed, the second workshop has completed 80% of the total number of small farm tools 2. Party A and Party B respectively accept the same number of freight transportation tasks. After 14 days of joint transportation, team a has 64 tons left and team B has 484 tons left. It is known that the working efficiency of team B is 60% of that of team A. how many tons does team a transport every day? 3. The grain store transported 260 bags of rice and flour. After selling one twelfth of the rice, the remaining rice was 7 bags less than flour. How many bags of rice were transported in?

1. Make a batch of small farm tools. The first workshop can process 50 pieces a day. If the second workshop does it for 10 days, it can complete the task. Now the two workshops cooperate. When this batch of tasks are completed, the second workshop has completed 80% of the total number of small farm tools
What are the days of cooperation
80% △ 1 / 10 = 8 days
First workshop 8 days processing
50 × 8 = 400
What is the total number of these small farm implements
400 (1-80%) = 2000
2. Party A and Party B respectively accept the same number of freight transportation tasks. After 14 days of joint transportation, team a has 64 tons left and team B has 484 tons left. It is known that the working efficiency of team B is 60% of that of team A. how many tons does team a transport every day?
Team B 14 days less than team a 14 days
484-64 = 420 tons
Team B carries less than team a every day
420 △ 14 = 30 tons
Team a transports every day
30 (1-60%) = 75 tons
3. The grain store transported 260 bags of rice and flour. After selling one twelfth of the rice, the remaining rice was 7 bags less than flour. How many bags of rice were transported in?
After selling one twelfth of the rice, the remaining rice is 7 bags less than flour,
It can be understood as
Flour is 1-1 / 12 of rice, more than 7 bags
Bring in the rice
(260-7) / (1 + 11 / 12) = 132 bags
