(1) Party A and Party B completed the whole journey of 1/3 in five days, so the work efficiency of both parties in 115;

(2) The remaining (2/3) 1/4 after two days' repair, that is, the whole process 1/6, so the working efficiency of Party B and Party C in 1 day is1/2;

③ Party A, Party B and Party C repaired the remaining roads within 4 days, that is, 1-1/3-1/6 =1/2, so the working efficiency of Party A, Party B and Party C in1day is/kloc-0.

③ Subtract ①, the work efficiency of a person 1 day is1/8-115 = 7/120;

③ Subtract ②, the work efficiency of a person 1 day is1/8-112 =1/24;

If you subtract the work efficiency of three people from the work efficiency of A and C, then the work efficiency of one person in B is1/8-7/120-1/24 =1/40.

Therefore, Party A's work efficiency is 1/24, working time is 5+4=9 days, and Party A's salary is (1/24) * 9 * 4560 =1710 yuan.

The work efficiency of Party B is 1/40, the working time is 5+2+4 =1/day, and the salary of Party B is (1/40) *1* 4560 =/kloc.

The work efficiency of Party C is 7/ 120, the working time is 2+4=6 days, and the salary of Party C is (7/120) * 6 * 4560 =1596 yuan.
