Question 635716: A can do half as much work as B in the same time and B can do one third as much work as C. If they can finish the work in 12 days, find in how many days can each finish the work.
Solution:
Let C does 1 work in x days, then
C = 1/x, B = 1/3x, A = 1/16x
Total work = 1
or, 12(1/x + 1/3x + 1/6x) = 1
Or, x = 1/18
So, C = 18 days, B = 54 days, C = 108 days. Am I right ? I am not sure.
