Three men A,B,C can complete a work separately in some
specified days(may be6,7,8).If they do the work together by
alternate days. Then how many days need to complete the
work?
Answer Posted / umesh7a
Three man's on day work = 1/6+1/7+1/8=73/168
three man's can complete the work in 1/73/168 days
= 168/73 days
Now if they works together fro the alternet days they will
complete the worksin 2*168/73 days
(If three mans working for the alternate days then work
completion time will be doubbled)
