As A, B and C, each working alone complete a job in 6, 8 and 12 days, respectively, they do 16,18and 112 of the job in a day.
Hence they together do 16+18+112=424+324+224=924=38 of the job in one day or complete the job in 83=223 days.
Note that work done by them is in the ratio 16:18:112424:324:2244:3:2.
As the work done by them is in the ratio of 4:3:2 (their sum is 4+3+2=9).
C's share in earnings will be $2340×29=2602340×219=$520.
