Answer 2

Explanation:

I want to ask that in the Question A&B are doing the work together in 6 days or while doing solo BTW

solving if A&B are doing the work together in 6 days

part of work A&B will finish together in one day = 1/6

part of work C will finish it alone in one day = 1/12

part of work they will finish while working together in one day

= 1/6+1/12=2+1/12=3/12=1/4

so part of work they will finish while working together =1÷1/4=4

So they will take 4 days to finish the work together .

if they takes 6 days alone then you follow the steps and that's simple.
