in 15 days ; A and C can do it in 20 days. In how many days will A, Band' C finish it, working all together?Also ,find the number of days taken by each to finish it working alone.
Read Solution (Total 1)
-
- (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. - 12 years agoHelpfull: Yes(0) No(0)
