A and B can do a work in 12 days,B and C in 15 days and C and A in 20 days.They all work together for 6 days and then A left. In how many more days can B and C finish the remaining work?
a>5 days
b>6 days
c>8 days
d>9 days
Read Solution (Total 1)
-
- a>5 days
(A+B)+(B+C)+(A+C)=2(A+B+C)=1/12+/15+/20
(A+B+C)'s one day work=12/120=1/10
in 6 days 6/10 of work is completed, remaining is 4/10 i.e 2/5 of work. B and C will finish it in 6 days.
