Some of the same rooms need wall painting. Three first-class technicians go to paint eight rooms a day. As a result, there are 50 square meters of future wall painting and painting. In the same time, five second-class technicians paint another 40 square meters of wall besides 10 rooms. Each first-class technician paints more than 10 square meters of wall in one day than the second-class technician, so the wall area of each room needs painting There are a group of pigeons and some pigeon cages. If 6 pigeons live in each pigeon cage, the remaining 3 pigeons have no pigeon cages to live in. If another 5 pigeons fly together with the original pigeons, each pigeon cage just lives in 8 pigeons. How many pigeons and pigeon cages are there?
One day's painting area of the first level technician is x, the second level technician is y, and the area of one wall is set as a
Series of equations
3X=8a-50
5Y=10a+40
X=Y+10
Solving equations
X=122
Y=112
a=52
The answer is 52 square meters
Set X pigeon cages
6x+3+5=8x
x=4
6X + 3 = 27
There are 4 pigeon cages and 27 pigeons
