A's 8day work+B's 12 days work+C's 6days work=1
(A+B)'s 8 day work+(B+C)'s 4day work+C's 2day work=1
=>8/(14 2/5)+4/12+C's 2day work=1
=>C's 2 day work=1-4/12-40/72=1/9
=>C's 1day work=1/18
so C can finish in18days.
As B+C 's 4 day work is=4/12.sso B+C 's 1day work=1/12
so B can finish it in=1/(1/12-1/18)=36days.
so A can finish it in 24days.
