A and B can complete a work in 12 days. B and C can complete the same work in 18 days. C and A can complete in 24 days. How many days will take for A, B and C combined together to complete the same amount of work?
1/a+1/b = 1/12
1/b+1/c = 1/18
1/c+1/a = 1/24
2(1/a+1/b+1/c) = (6+4+3)/72
or 1/a+1/b+1/c = 13/(2*72)
or A , B and C together can finish in 144/13 or 11.1 days.
