Answer 2

Step-by-step explanation:

A can do a work in 3 days, B in 6 days and C can do it in 9days

Part of work done by A in one day =1/3

Part of work done by B in one day=1/6

part of work done by C in one day=1/9

How many days will take together to complete the work?

If they work together then part of work finished by A , B and C together

= 1/3 +1/6 + 1/9

= (6+3+2)/18

= 11/18

so, they can do it in 11/18 days
