There are 336 workers in workshop a and workshop B, 5 / 7 of workshop a and 3 / 7 of workshop B. There are 188 workers in total. How many people are there in workshop a and workshop B?

There are 336 workers in workshop a and workshop B, 5 / 7 of workshop a and 3 / 7 of workshop B. There are 188 workers in total. How many people are there in workshop a and workshop B?

There are 336-x workers in workshop a and 336-x workers in workshop B
5 / 7X plus 3 / 7 (336-x) = 188
I'll write it later

Party A and Party B work together to build a road in two days. Originally, party a planned to build 3 / 4 of Party B's road. When the task was completed, party a built 600 meters more. At this time, Party B is 2 / 3 of Party A's road,
How many meters should be repaired in the original plan?

The total length of the original plan a repair: 3 (3 + 4) = 3 / 7
The total length of the actual repair: 3 (2 + 3) = 3 / 5
Total length: 600 ÷ (3 / 5-3 / 7) = 3500 m
3500 × 3 / 7 = 1500m
A: the original plan is to build 1500 meters

It is planned that the task of building a road will be assigned to two engineering teams, team a and team B. the two teams will start from both ends at the same time. When the two teams finish building the road, team a and team B will complete the task
The ratio of workload is 5:4. When the actual construction starts at the same time, the efficiency is increased by 20% because team a has updated the equipment. When the two teams finish the road, team B will build 80 meters less than planned. How many meters is the total length of the road?

Obviously, the work done by the engineering team is proportional to the efficiency
∵ the ratio of the workload completed by team a and team B is 5 ∶ 4. The original workload of team a and team B can be set as 5A and 4A respectively, and the original efficiency of team a and team B and team C can be set as 5x and 4x respectively
According to the meaning of the title, there are: (5a + 80) / [5x (1 + 20%)] = (4a-80) / (4x),
∴（5a＋80）/6＝（4a－80）/4＝a－20,∴5a＋80＝6a－120,∴a＝200,
∴5a＝1000、4a＝800.
The total length of the road is 1800 meters
