Answer:
Step-by-step explanation:
A can do the work in 3 days. So in 1 day A does 1 amount of work
3
B takes double the time as A. So, B can do the work in 6 days. So, in 1 day B does 1 amount of work
6
C takes one more day in addition to the time taken by B. So, C can do the work in 7 days.
So, in 1 day C does 1 amount of work
7
When they work together, in 1 day they complete how much work?
In one day - A, B and C together complete = 1 + 1 + 1 = 9 amount of work
3 6 7 14
