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

so 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.

a+b=12 b+c=18 c+a=24 a+b+c=(12+18+24)/2 = 27
