Answer: It takes 1.56 days
Step-by-step explanation:
In one day
- A can do 1/3 rd of the work.
- B can do 1/6 th of the work.
- C can do 1/7 th of the work.
Totally in one day together they can do - 1/3 + 1/6 + 1/7
=14/42 + 7/42 + 6/42
=27/42 of the work
To complete the whole work it takes= 1/ (27/42)
=42/27 days
=1.55555....
which is approximately equal to 1.56.
Therfore it takes 1.56 days
