Anonymous users2024-02-07I've thought it all about, and mine is definitely right. The third floor is just one step away; Everyone's efficiency came out, but he ignored the fact that everyone worked a different number of days.
A did 6+5=11 days, B did 6+4+5=15 days, and C did 4+5=9 days.
Suppose that the work efficiency of A, B and C is x, y, and z
Then (x+y)*6=1 3
y+z)*4=1/4
x+y+z)*5=5/12
The solution is x=1 48, y=5 144, z=1 36
So A did the engineering of 1 48 * 11 = 11 48
B did the work of 5 144 * 15 = 25 48
C did the project of 1 36 * 9 = 1 4
A's salary = 540 * 11 48 =
B's salary = 540 * 25 48 =
C's salary = 540 * 1 4 = 135

Anonymous users2024-02-06A and B first practiced together for 6 days: 1 3 2=1 6 The remaining wall was repaired together for 5 days: 1-1 4-1 3=5 12 5 12 3=5 36 A practiced a total of a fraction:
A deserves: 540 * 11 36 = 165 yuan.
A and B first practiced together for 6 days, and B repaired together: 1 3 2=1 6 B and C practiced together for 4 days, and B repaired in 4 days: 1 4 2=1 8 The remaining walls were repaired by 3 people for 5 days
A few fractions of what B has done: 1 6 + 1 8 + 5 36 = 31 72 B deserves: 540 * 31 72 = yuan.
B and C worked together for 4 days, and C repaired it for 4 days: 1 4 2 = 1 8 The remaining wall was repaired together for 3 days, and C repaired it for 5 days: 1-1 4-1 3=5 12 5 12 3=5 36
C has taken a few fractions: 1 8 + 5 36 = 19 72 C deserves: 540 * 19 72 = yuan.

Anonymous users2024-02-05The work efficiency of the joint study of A and B 1 3 divided by 6 = 1 18 The work efficiency of the joint study of B and C 1 4 divided by 4 = 1 16 The work efficiency of the joint study of A, B and C (1-1 3-1 4) divided by 5 = 1 12 The work efficiency of C = the work efficiency of the three people - the work of the two people A and B = 1 12-1 18 = 1 36
A's work efficiency = three-person practice - B, C's two-person practice = 1 12-1 16 = 1 48
B's work efficiency = 1 18 + 1 16-1 12 = 5 144 A's work efficiency: B: C = 1 48:5 144:1 36 = 3:5:4 So A's due money = 540*3 12 = 135
B = 540 * 5 12 = 225
C = 540 * 4 12 = 180
