(A+B)'s one day work is 1/12
(B+C)'s one day work is 1/15
(C+A)'s one day work is 1/20
Thus.2(A+B+C)'s one day work=1/12+1/15+1/20=1/5
Thus, all of them together can complete the work in 10 days
Now, A's one day work is 1/10-1/15=1/30
B's one day work =1/10-1/20=1/20
C's one day work =1/10-1/121/60
Thus, A, B and C each can complete the work in 30,20 and 60 days respectively.
