like A can do in 6 day and B can do in 8 and C can do in 12 days
but b left after working for 6 days for how many no of day A and C
should work

• work done by b in 6 days =6/8=3/4
  remaining work=1/4
  in 1 day a amd c together do (1/6)+(1/12)=3/12 work i.e 1/4
  hence they will require 1 day

• Based on capacities
  A's capacity(6days) i.e 16.66%
  B's capacity(8days) i.e 12.5%
  C's capacity(12days) i.e 8.33%
  B's work in 6 days=12.5*6=75%
  remaining 25% work will be done by A and C their's capacity=16.66+8.33=25%
  so they can finish work in 1 day(Ans)

• A's 1day work=1/6
  B's 1day work=1/8
  c's 1day work=1/12
  B's 6days work=6(1/8)=3/4, remaining work=1-(3/4)=1/4
  work done by (A+c) for 1day =1/6+1/12=1/4
  (A+C) does their work in 4 days
  and b's remaining work in another 4days
  therefore,8Days(ans)
  
  (not sure abt the ans)
