Ahother steps:
A + B can do in 18 days ,
B + C can do it in 24 days ,
A + C can do it in 36 days.
A+B+C do/day = (1/18+1/24+1/36)/2 = (4+3+2)/72 = 1/16
B does/day = 1/16-1/36 = (9-4)/144 = 5/144
B can do in 144/5 = 28.8 days
A + B can do in 18 days ,
B + C can do it in 24 days ,
A + C can do it in 36 days.
A+B+C do/day = (1/18+1/24+1/36)/2 = (4+3+2)/72 = 1/16
B does/day = 1/16-1/36 = (9-4)/144 = 5/144
B can do in 144/5 = 28.8 days
