If A can do as much work in 4 hours as B can do in 8 hours, how long will it take C to complete a piece of work , one third of which has been done by A working 8 hours and B working 18 hours?

• incomplete question..!!!
  there must be some relation between the capacity of doing work either between A and C or between B and C

• c will complete in 6 hrs.becoz a+b completed the work in (32/12)hrs in 1st case nd in 2nd case they completed in (24/13)hrs.

• it depends on the efficiency of c .
  a's 1 day work = 2/b; b's 1 day work =1/b
  16/b +18/b =1/3 w
  w=34/102
  remaining work=68/102
  now it depends on c
