A alone can do the work in=12 days
So in 1 day he do=1/12 part of work
Similarly, B can do part of work in 1 day=1/18
Let the part of work completed by C =1/x
Now A, B and C together can do work
in=4days
So in 1 day they together do 1/4 part of work
So 1/12+1/18+1/x=1/4
1/x=1/4-1/12-1/18
1/x =9-3-2/36
1/x=4/36
1/x=1/9
x=9
So C alone can do the work in 9 days
So in 1 day he do=1/12 part of work
Similarly, B can do part of work in 1 day=1/18
Let the part of work completed by C =1/x
Now A, B and C together can do work
in=4days
So in 1 day they together do 1/4 part of work
So 1/12+1/18+1/x=1/4
1/x=1/4-1/12-1/18
1/x =9-3-2/36
1/x=4/36
1/x=1/9
x=9
So C alone can do the work in 9 days
