Let the work to be done is W
A and B can do the the work in 24 days
The Work A and B do together in one day is W/24 ⇒ A + B = W/24
A , B , C can do the work in 8 days
The Work A , B , C do together in one day is W/8 ⇒ A + B + C = W/8
substituting A + B = W/24 ⇒ we get C = W/12
the work C do's in one day is W/12 ⇒ C completes the work alone in 12 days
